Introduction

The DHT20 temperature & humidity sensor is the newly upgraded version of the DHT11. Data accuracy, stability, response speed, measurement range are greatly improved up.

DHT20 is a brand new ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor element and a standard on-chip temperature element. All sensors are factory calibrated and characterized by low power, high precision & stability, fast response, and strong anti-interference. Moreover, the DHT20 performance parameters of accuracy, power supply voltage, measurement range and response time have been enhanced greatly over the previous generation, making it more cost-effective.

Besides that, the DHT20 temperature & humidity sensor employs I2C digital output protocol, which is very suitable for HVAC, automobiles, data loggers, weather stations, home appliances, and other related temperature and humidity detection and controlled areas.
