High precision AHT10 I2C Temperature and humidity sensor module better than SHT20
 
Introduction:
AHT10, a new generation of temperature and humidity sensor has established a new standard in terms of size and intelligence: it is embedded in a dual-row flat no-lead SMD package suitable for reflow soldering, with a bottom surface of 4 x 5mm and a height of 1.6mm. The sensor outputs a calibrated digital signal in a standard I 2C format. AHT10 is equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor element and a standard on-chip temperature sensor element. Its performance has been greatly improved or even exceeded the reliability level of the previous generation of sensors. A generation of temperature and humidity sensors have been improved to make their performance more stable in harsh environments.
