AHT21B humidity sensor on a breakout board.

• Relative humidity and temperature output
• Superior sensor performance, typical accuracy RH: ±3%, T: ±0.5°C
• Fully calibrated and processed digital output, I²C protocol, the address is 0x38
• Wide voltage support 2.2 to 5.5V DC
• Excellent long-term stability
• Fast-response and anti-interference capability

General Information: AHT21B uses a newly designed ASIC dedicated chip, and improved MEMS semiconductor capacitive humidity sensor component and a standard on-chip temperature sensor component. Its performance has been improved and the reliability is better then the previous generation of sensor, which makes it more stable in harsh conditions. Each sensor had been calibrated and tested.
