Welcome to our shop, where your satisfaction is our priority. 10pcs AHT10 AHT20 AHT21 High Precision Digital Temperature Humidity Sensor Measurement Module I2C Communication Replace DHT11 SHT20 (AHT21) Product Gallery Product Details Description: AHT21 a new generation of temperature and humidity sensors, sets a new standard in size and intelligence: it is embedded in a dual-row flat leadless SMD package for reflow soldering with a 4 x 5mm bottom and a height of 1.6mm. The sensor outputs a calibrated digital signal in standard I2C format. The AHT21 is equipped with a newly designed ASIC-specific chip, an improved MEMS semiconductor capacitive humidity sensing element and a standard on-chip temperature sensing element. Its performance has been greatly improved beyond the reliability level of previous generation sensors. The first generation of temperature and humidity sensors have been improved to make them more stable in harsh environments.Note: Please make sure put it in the environment of humidity greater 80% for 12 hours to ensure the accuracy is restored before using.Characteristics: 1.
