In this tutorial, you will learn about DHT22 Temperature and Humidity Sensor Module. We will interface this sensor module with Arduino Uno.

Humidity Sensor (DHT22) The DHT-11 (also named as AM2302) is a digital-output, relative humidity, and temperature sensor. It uses a capacitive humidity sensor and a thermistor to measure the ...

Moreover, you can get the information from any sensor and analyse it graphically or in any user-defined format from anywhere in the world. The IoT using Arduino microcontroller (MCU) is easy and fun ...

Here we report development of a zinc oxide (ZnO) nanorods based humidity sensor prototype using Arduino Uno microcontroller platform. A commercial humidity sensor (DHT11) was also connected with the ...

Circuit and Working Fig. 2 shows the circuit diagram of the humidifier. The system is built around an Arduino Uno (MOD1), a 5V SPDT relay module, a humidity sensor (DHT22), an ultrasonic humidifier, ...

In this article, we discussed how the DHT11 Temperature and humidity sensor works and how we can use it with Arduino.

Conclusion The DHT11 sensor, in combination with Arduino, provides a reliable and efficient way to measure temperature and humidity. The project demonstrates the sensor’s practicality in various ...
