Fetching or posting data over the Internet is one of the main core functions of the IoT device. Doing so over HTTP is better implemented in NodeMCU ESP8366 Arduino libraries, but makes things more difficult for HTTPS requests. In this post, I will talk about the most common approaches used by the community and will show you the method to make Secure HTTPS Requests to URL Using NodeMCU ESP8266. No special certificates or fingerprints are required to manually code the program using this method.
HTTPS Requests to URL Using ESP8266- What are CA certificates?
- HTTPS Requests to URL Using Fingerprints - secure but annoying
- HTTPS Requests to URL Using client.setInsecure() - easy but unsafe
- HTTPS Requests to URL with the IoT framework
- Generating a certificate store
- HTTPS Requests to URL Using ESP8266 Source Code
- Conclusion
HTTPS is a method of requesting HTTP over a TLS (formerly SSL) connection. By doing so, the data sent between and behind your computer and server is encrypted and secure. The good news is that this protocol can be used in conjunction with the ESP8266 WiFiClientSecure class. The bad news is those common methods have some major disadvantages.
First I will discuss the two most common methods, and next, I will describe the generic solutions to their problems.
What are CA certificates?
Before diving into the details I will briefly describe the basic principles of secure HTTPS requests in general terms.
Generally, there is a certificate for each website.

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.

In this project, we will make an Internet Clock Using NodeMCU ESP8266 and 16x2 LCD without RTC Module. This simple Internet Clock using NodeMCU ESP8266 gets the current Date and Time from NTP Client. Here, NTP stands for Network Time Protocol.
Overview
In this project, we will design an Internet Clock using NodeMCU ESP8266 Wifi Module. We will fetch the time and date from the internet using the ESP8266 controller. Actually, we all know that the internet time clock has a precision of 0.02 to 0.10 seconds. While being on lockdown due to coronavirus, I spent some time browsing the internet and found an Internet Clock that is made using RTC Modules like DS1307, DS3231 or PCF8563 to get the time. But, due to lockdown, there is no availability of any RTC Module.
So I tried making an Internet Clock Using NodeMCU ESP8266 and 16x2 LCD without RTC Module. Instead, I used the NTP client to get the current date and time through the Internet. Actually, while surfing the internet I found some disadvantages as well. The RTC has poor accuracy and requires manual adjustments from time to time to keep date and time-synchronized.
Hence, the solution I Founded here is to use the Network Time Protocol (NTP). If your NodeMCU ESP8266 project has access to the Internet, you can get date and time (with precision within a few milliseconds of UTC) for FREE. Basically, we don’t need any additional hardware to make this project. You

Overview: BME680 IAQ Monitoring on webserver & OLED Display
In this project, we will make the Indoor Air Quality Monitoring with BME680 & ESP8266 Webserver and 0.96" SSD1306 OLED Display. We will use the advanced BSEC library for BME680 and monitor its parameters including IAQ on OLED Display and ESP8266 web server simultaneously. So, that you can monitor the sensor values remotely from your local network.
In our previous projects, we have interfaced Arduino with an integrated BME680 Environmental Sensor. Further, we made an IoT-based Indoor Air Quality Monitoring system on the Blynk IoT Cloud. But the drawback of that project was, we could not calculate the IAQ value i.e. Index of Air Quality, C02 equivalent, and percentage of (VOC) Volatile Organic Compound. we could only measure the environmental parameters like temperature, humidity, pressure, altitude, dew point, and Gas Resistance.
So in this tutorial, we will use a highly advanced BME680 Library called BSEC library, Which is now supported by NodeMCU ESP8266 and ESP32 Development Board. With the help of this library, we can measure the Temperature, Humidity, Pressure, value of IAQ, equivalent carbon dioxide, and Total volatile compound. SSD1306 0.96” OLED Display is used to monitor environmental data. We can also use ESP8266 Webserver to remotely monitor those values. The ESP8266 connects to your WiFi network & uploads the data regularly to the webserver.

Overview: Power Supply board for NodeMCU
In this tutorial, we will make a Power Supply board for NodeMCU ESP8266. Here, we will use a battery boost converter circuit to operate the NodeMCU with a 3.7V battery. Obviously, the battery gets discharge after using it for a long time. So, we need to integrate a battery charging circuit that has a built-in battery management system. This will protect your battery from over-charging and over-discharging, so the battery lasts longer.
Most of the lithium-ion batteries found in the market come with 3.7V and 4.2V when fully charged. This is not enough to power up the NodeMCU Board. So we need to convert the voltage of the battery to 5V. For this reason, we are using a small boost converter module. Which is made using some inductors, IC & resistor. Similarly, the TP4056 Battery Charger Module is used to charge and manage the battery.
Besides this, if you don’t want to power the NodeMCU board using the battery, you can use the DC Power Adapter. we can power this board using a 9V/12V DC Adapter. The LM7805 Voltage regulator IC will limit the voltage up to 5V only.
Components Required
Following are the components required for making this Power Supply board for NodeMCU ESP8266. We can easily purchase all the components from Amazon. We provided the component purchase link below.
Power Required By NodeMCU

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
