Product Details


Product Introduction

The DHT22 digital temperature and humidity sensor is a combined temperature and humidity sensor with a calibrated digital signal output. It utilizes dedicated digital module acquisition and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability. The sensor consists of a capacitive humidity sensor and an NTC temperature sensor, connected to a high-performance 8-bit microcontroller. This product offers fast response, strong anti-interference capabilities, and a very cost-effective price. Each DHT22 sensor is calibrated in a humidity calibration laboratory.
Calibration coefficients are stored as a program in 0TP memory and are used internally by the sensor during signal processing. A single-wire serial interface facilitates quick and easy system integration. Its compact size, low power consumption, and signal transmission distance of up to 20 meters make it an ideal choice for a wide range of applications, even in the most demanding environments.
The product is packaged in a 4-pin, single-row package for easy connection, and special packaging options are available upon request.
