Please receive this module and leave it in the environment with humidity 80% for 12 hours to accuracy is restored. The AHT10, a 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 4x5mm base and a height of 1.6mm. The sensor outputs a calibrated digital signal in standard ICH 2C format. The AHT10 is equipped with a newly designed ASIC-specific chip, an improved MEMS semiconductor capacitive moisture sensing elementsand a standard on-chip temperature sensing element. Its performance has greatly improved over 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.
