DHT22 AM2302 temperature and humidity sensor with wires, Arduino module
0
Description
DHT22 AM2302 temperature and humidity sensor for ESP8266, ESP32, Arduino, Raspberry Pi
DHT22 (AM2302) temperature and humidity sensor is a highly sensitive device designed for precise measurements in various conditions. The module offers high reliability and stable readings.
The sensor measures temperature over a wide range from -40°C to +125°C with an accuracy of ±0.2°C. This ensures trustworthy, precise results in demanding projects.
Humidity measurement covers the full range from 0 to 100% RH with an accuracy of ±5% RH. Humidity measurement resolution is 8 bits with precision down to 0.1% RH, enabling detailed tracking of air parameter changes.
The module is powered from 3.3V to 6V. Standby current consumption is at most 60 µA, which is highly advantageous for battery-powered applications or energy-saving operation. During active measurement, current draw rises to at most 1.6 mA. A measurement takes only 2 seconds.
The kit includes 3 female-to-female jumper wires for quick integration of the sensor with various devices and prototyping systems.
