In this tutorial, I’ll first go into a little background about humidity, then I’ll explain how the DHT11 measures humidity. After that, I’ll show you how to connect the DHT11 to anArduinoand give you some example code so you can use the DHT11 in your own projects. BONUS: I ma...
We have another tutorial on the DHT11 for theArduinothat goes into detail on relative humidity and how the DHT11 measures it. So instead of repeating all of that here, check outHow to Set Up the DHT11 Humidity Sensor on an Arduino, then come back for the specifics on setting it up o...
DHT11 Sensor: Connect this to NodeMCUsD4pin. MQ-135 Sensor: Connect this to NodeMCUsA0pin. PIR Sensor: Connect this to NodeMCUsD3pin. 5V Buzzer: Connect this to NodeMCUsD0pin. Kitchen appliances: Whatever electrical kitchen appliances you have, you must connect them to the NodeMCU using the...
Introduction: How to Make RGB Lighting Clock🌈 Neon Color Changing Wall Clock Using Ws2812 LEDs, DS3231, DHT11 and Arduino UNO 1 Step 1: Hi guys, today this project we using Arduino UNO, and get the real time via DS3231 clock module, get temperature via DHT11 sensor. And then, let...
Wiring – Connecting HC-SR04 to Arduino UNO The wiring diagram below shows you how to connect the HC-SR04 sensor to the Arduino. HC-SR04 with Arduino wiring diagram The code examples below use digital pin 2 and 3 for the trigger and echo pin respectively, but of course you can change th...

If you are interesting to make data recorder or data Logger of a sensors and to record its data in a file. here are the following links: 1-Temperature and light intensity data logging https://youtu.be/gd-a8Y5GF3A 2-DHT11 data recorder with Arduino & micro SD Card ...
RPi.GPIO library can only be used with Raspberry Pi, whereas PinPong enables Python-based control of Arduino, micro:bit, and other microcontrollers. PinPong operates by flashing a specific firmware onto open-source hardware, allowing it to communicate with a computer via serial communication and ...
Connect the Vcc and ground pin of the DHT11 sensor to the 5V and ground of the Arduino nano. Connect the output pin of the DHT11 sensor to the Pin2 and the IN pin of the relay module to the Pin3 of the Arduino. Power up the relay module through Arduino and connect the positive...
