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.
Components Required
Following are the components required for making IoT based Fall Detection System.
- NodeMCU ESP8266 WiFi development board
- MPU6050 Accelerometer and Gyroscope sensor
- Jumper Wires

Today in this project we are going to make IoT Based Flood Monitoring System Using NodeMCU, Ultrasonic HC-SR04 Sensor & Thingspeak IoT Platform. As we all know that Flood is one of the major well Known Natural disasters. It causes a huge amount of loss to our environment and living beings as well. So in these cases, it is very important to get emergency alerts of the water level situation in different conditions in the river bed.
IoT Based Flood Monitoring System Using NodeMCU & Thingspeak
The purpose of this project is to sense the water level in river beds and check if they are in normal condition. If they reach beyond the limit, then it alerts people through LED signals with buzzer sound as well as internet applications. Here we are using the Ultrasonic HC-SR04 sensor to sense the river level and NodeMCU ESP8266 Microcontroller for data processing. The processed data will be uploaded to the ThingSpeak IoT Cloud Platform. Using which river levels can be monitored graphically from anywhere in the world. theiotprojects.com/iot-based-flood-monitoring-system-usin...
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.

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.

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.
