Product Descriptions

DHT20 is a new upgraded product of DHT11, equipped with a dedicated ASIC sensor chip, ahigh-performance semiconductor silicon-based 

capacitive humidity sensor and a standardon- chip temperature sensor, and uses a standard I2C data output signal format. Its 

performancehasbeen greatly improved and has exceeded the reliability level of the previous generationsensor(DHT11).The new generation of 

upgraded products have been improved to make their performance more stable in high temperature and high humidity environments; at the 

same time, the accuracy, response time, and measurement range of the product have been greatly improved. Each sensor is rigorously 

calibrated and tested before leaving the factory to ensure and satisfycustomer’s large-scale applications.

Product Applications

The DHT20 is a kind of sensor of humidity and temperature with digital I²C output. It canbeapplied to HVAC, dehumidifier, testing and 

inspection equipment, consumer products, automobiles, automatic control, data loggers, weather stations, home appliances, humidity control, 

medical and other application fields which need to detect and control temperature and humidity.
