Fundación Cibervoluntarios organiza en Madrid el segundo encuentro para intercambio de buenas prácticas del proyecto Europeo "IoT for everyone", proyecto Erasmus + que realizamos con socios de Italia, Túnez y Polonia. Uno de los grandes desafíos en la 4ª revolución industrial es la infinidad de aplicaciones y plataformas tecnológicas que se van incorporando a nuestro día a día, como, por ejemplo, la interconexión digital de objetos cotidianos con internet, lo que se conoce como Internet of Things o Internet de las Cosas. Este proyecto se basa en una idea clave: el desafío para acercar a todas las personas las oportunidades y distintos usos de la tecnología IoT, especialmente aquellas personas más alejadas del sector tecnológico sin conocimiento especializado de programación, gracias a la facilidad de usabilidad de TUNIOT, una herramienta desarrollada por uno de los socios.
Qué es el Internet de las Cosas, qué supondrá en un futuro muy próximo y qué hacer para aumentar la seguridad y protección de datos. El Internet de las Cosas es un concepto que cada vez toma más relevancia, pero aún no termina de cuajar en los hogares. La idea que intenta representar queda bastante bien ilustrada por su nombre, cosas cotidianas, app que se conectan al Internet, pero en realidad se trata de mucho más que eso. Si tuviéramos que dar una definición del Internet de las cosas probablemente lo mejor sería decir que se trata de una red que interconecta objetos físicos valiéndose del Internet.
El proyecto, de dos años de duración, persigue una serie de objetivos:
• El uso y conocimiento de la herramienta innovadora TUNIOT, desarrollada por Adel Kassah, que facilita el proceso de programar ya que permite la creación de un código sin previo conocimiento de lenguaje de programación a través de bloques predeterminados que se ensamblan del mismo modo que lo hacen las piezas de un puzzle.
• Acercar la tecnología y despertar interés de personas que, o no estén familiarizadas con el lenguaje de programación y sus usos, o tengan menos recursos y oportunidades, para que puedan utilizar esta tecnología y sus diferentes aplicaciones a nivel personal y/o profesional. Y de esta manera, trasladar este interés para fomentar su empleabilidad, espíritu emprendedor y competencias digitales más especializadas.
• Facilitar el uso de Arduino gracias a la herramienta TUNIOT utilizando la placa ESP8266 conectada a distintos tipos de sensores (movimiento, luz, humedad, vibración, etc.).
• Conectar los objetos automatizados creados con la placa ESP8266 a nuestros dispositivos móviles para así poder controlarlos a distancia, convirtiendo estos objetos en tecnología IoT.

Today we will learn to interface MPU6050 Sensor with NodeMCU to Monitor MPU6050 Tilt Angle on Blynk IoT Application.

Introduction
In this post, we will learn how to Monitor MPU6050 Tilt Angle on Blynk using NodeMCU. This can be done by simply interfacing the MPU6050 6-axis Gyro/Accelerometer Sensor with NodeMCU. The Accelerometer sends X, Y, and Z acceleration forces. We need to convert those forces into X, Y, Z 3D angle to determine the 3D Orientation of the sensor. Then the measured tilt angle is sent to the Blynk Application using the Blynk cloud. So the tilt position can be monitored in IoT.
The gyroscope measures the position of rotation velocity or angle along with the X, Y, and Z-axis. It uses MEMS technology and the Coriolis effect for measurement. The outputs of the gyroscope are degrees per second, so to get the angular position, we just need to integrate the angular velocity.
You can refer to the previous post where we measured tilt angle using MPU6050 and send an SMS notification as fall detected when the defined threshold value is reached: IoT Based Fall Detection system using MPU6050 & NodeMCU ESP8266

Given I will have the EEPROM for data backup I may remove some of the historical data. It is cluttering. Most recent update is at the bottom of the list and server is designed to supply the last 60 updates on a rolling basis. This gives data for the last 10 hours or so on screen.
Sender unit is currently sitting on top of a column at a fixed height so doesn't change but temperature, super cap voltage and time between updates are real data.
Overview
The RFID based attendance system is developed using PHP, CSS, and Javascript. An RFID Based Attendance System Using NodeMCU is a modern attendance system. Hence, is a very interesting project. It can be useful in different places like schools, Colleges, industry and private organizations to register the attendance of students, teachers, employees, etc. to tabulate monthly/daily working hours automatically. When the person with the correct RFID card swipes his/her RFID tag, His/Her arrival time will be stored in system Log. Usually, when the same person swipes his/her RFID tag again, the system will save it as his/her leaving time.
RFID Based Attendance System Using NodeMCU with PHP Web App
The RFID attendance system is developed with the IoT platform. We have used NodeMCU ESP8266 development board with MF-RC522 Module to send the card UID to the PHP Web app and store data into the website database. Basically, the admin plays an important role in the management of this system. theiotprojects.com/rfid-based-attendance-system-using-nod...
As we all know the fall detection system is very handy for older people in day to day life. Because it can notify the person or family member when it detects a fall and reduces the risk of delay in medical attention. So, it leads to the development of different types of automatic fall detection systems. Nowadays, we can find fall detectors even in smartwatches, fitness trackers, and other types of wearables. IoT-based fall detector devices can save a life in an emergency. So in today's tutorial, we are going to build IoT based fall detection device using NodeMCU and MPU6050 sensor module.
The MPU6050 sensor module has built-in a gyroscope and an accelerometer sensor. The gyroscope is used to determine the orientation and the accelerometer provides information about the angular parameter such as the X, Y, and Z-axis data. For detecting fall, we will compare the acceleration magnitude with the threshold value. If the fall is detected, the device will send an SMS to the concerned person. NodeMCU ESP8266 is used here as a microcontroller and Wi-Fi module to connect with IFTTT to send SMS.

Overview: IoT Pulse Oximeter
In this project, you will learn to make IoT based Pulse Oximeter using NodeMCU ESP8266, MAX30100, and Blynk Application. In our previous project, we have made a compact Arduino-based Pulse oximeter in which Pulse rate and Sp02 level are shown in OLED Display. But in today's project, we can monitor those values from anywhere in the world using the Blynk IoT cloud platform.
Components Required
To make this IoT based Pulse oximeter you will need the NodeMCU ESP8266 Development board. A 0.96" SSD1306 OLED Display, MAX30100 Pulse oximeter sensor, few jumper cables, and breadboard. You can buy all these components from the Amazon link provided below.
Working of MAX30100 Pulse Oximeter Sensor
The sensor has two LEDs, one emitting red light, the other emitting infrared light. Infrared light is required for pulse rate. But, Both red light and infrared light are required for measuring Sp02 levels in the blood.
When the heart pumps the blood, the oxygen level is increased because there is more blood. But, when the heart rests, there is a decrease in oxygenated blood. Hence, the pulse rate is determined by getting the time between the rise and fall of oxygenated blood.
The oxygenated blood absorbs more infrared light and passes more red light. But, deoxygenated blood absorbs red light and passes more infrared light.

In this tutorial, you will learn how to make a LoRa based IoT Smart Agriculture Monitoring and Automatic Irrigation System using ESP8266 NodeMCU, Arduino Nano, and the new Blynk IoT 2.0 platform.
Overview: LoRa based IoT Smart Irrigation & Monitoring System
Here on the sensor node, we will use the Arduino Nano board and SX1278 LoRa-02 Transceiver module. Then we will interface multiple sensors like capacitive soil moisture sensor v1.2 to measure the quantity of water present in the soil. DS18B20 waterproof temperature sensor to measure the temperature of the soil. Similarly, In the cold season plants die due to fog and low temperature. Thus, DHT11/DHT22 Temperature & Humidity sensor is used to measure the temperature and humidity of surroundings. A 5V Single channel relay module and water Pump are used for an automatic irrigation system.
Previously, I had made an IoT Smart Agriculture Monitoring & Irrigation System. But, the area where I was working do not have WiFi Signals. My home is around 700/800 Meters away from the agricultural field. So, I couldn't receive any WiFi signals there. Hence, I cannot monitor and control this device over the internet.
As said, "when there's a will there's a way". I found these SX1278 LoRa transceiver modules laying around. So, I decided to use Arduino Nano, Capacitive soil moisture sensor, DHT22 sensor, DS18B20 sensor, 5 Volt relay, DC Water Pump, and SX1278 LoRa-02 module on the transmitter side.

This tutorial is all about DHT11 Temperature and Humidity Monitor with NodeMCU on the ThingSpeak server. It clarifies how we can use the ThingSpeak cloud service provider to log DHT11 Temperature and Humidity data using NodeMCU.
Here I am using Arduino IDE to program NodeMCU ESP8266. Actually, you will learn to configure NodeMCU ESP8266 board to monitor DHT11 sensor temperature and humidity values.
Also check these previous articles:
- Interfacing DHT11 Humidity & Temperature Sensor with Arduino & LCD
- IoT Weather Station using DHT11 Sensor
- NodeMCU ESP8266 Monitoring DHT11/DHT22 Temperature and Humidity with Local Web Server
Components Required
You just need a NodeMCU ESP-12E Wi-Fi Development board and a humidity sensor DHT11 or DHT22. Besides this, it requires a breadboard and connecting wires.
DHT11 Temperature & Humidity Sensor:
The DHT11 is a primary, ultra-low-cost digital temperature, and humidity sensor. To measure the surrounding air DHT11 uses a capacitive humidity sensor and a thermistor. And then spits out a digital signal on the data pin (no analog input pins needed).
It’s quite simple to use but requires precise timing to capture data. The entire real drawback of this sensor is you can only get new data from it once every 2 seconds. So when using the DHT library, sensor readings are up to 2 seconds old.
Circuit Diagram & Connection:
The wiring of DHT11 sensor with NodeMCU is very simple.

Overview: Temperature based Automatic IoT Fan
The main objective of this project is to build IoT based temperature control fan using NodeMCU ESP8266 & Blynk cloud for home automation. This device will be able to control your AC Home Appliances like AC, Fan, Heater, Cooler, or even light bulb, etc. Suppose you came from work, enter the room, and feel hot. After a while you want your cooler or fan to be “ON” automatically, and then “OFF” when the room temperature is back to normal. If you are searching for such a project, then you’re in the right place.
Nowadays, technology is advancing and houses are getting smarter. Modern houses are usually shifting from conventional switches to some kind of IoT-based centralized control system. In this project, we will use the ESP8266 NodeMCU development board, a DHT11/DHT22 Temperature, and Humidity Sensor, and a relay module to control your fan/cooler automatically based on your room temperature. We use the Blynk IoT app for monitoring the DHT11/DHT22 sensor temperature and humidity data and set temperature thresholds. When Temperature rises above the threshold temperature, the cooling fan connected to a relay will start automatically.
Working of Temperature-control Fan for Home Automation System
This temperature-based automatic fan control system comprises components like the ESP8266 board, Relay, and Temperature Sensor. The entire system depends on the Relay and DHT11/DHT22 sensor.
