Overview of this DHT22 Temprature and Humidity Sensor
Introducing the DHT22 Temperature and Humidity Sensor Module at the best price in India with Roboway. This DHT22 temperature and humidity sensor measures temperature and humidity in the air with good accuracy. This sensor can measure temperature from -40°C to +80°C and humidity from 0% to 100% RH, making it suitable for both indoor and outdoor environments. It is mostly use for battery-powered and energy-saving applications, as it only takes readings every 2 seconds.
The sensor gives data in a digital format and making it easy to use with microcontrollers like Arduino, ESP32, Raspberry Pi, etc. It is Built-in capacitive humidity sensor and thermistor ensure consistent performance over time. It can be placed easily in small spaces for portable or embedded systems.
Features
