Data Sheet AHT21B
Humidity and Temperature Module
• Relative humidity and temperature output • Superior sensor performance, typical accuracy RH: ±3%, T: ±0.5℃ • Fully calibrated and processed digital output, I²C protocol • Wide voltage support 2.2 to 5.5V DC • Excellent long-term stability • Fast-response and anti-interference capability
Product Summary AHT21B is equipped with a newly designed ASIC dedicated chip, an improved MEMS semiconductor capacitive humidity sensor component and a standard on-chip temperature sensor component. Its performance has been greatly improved and even beyond the reliability level of the previous generation of sensor, which make it more stable in the harsh conditions. Each sensor had been rigorously calibrated and tested.
