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 the sensor, which makes it more stable in harsh conditions. Each sensor had been rigorously calibrated and tested. Due to the improvement and miniaturization of the sensors, it is more cost-effective.
1. Product Overview
AHT21B is geared up with a recently designed ASIC dedicated chip, an enhanced MEMS semiconductor capacitive humidity sensor port, and an actual on-chip temperature sensing unit element. Its performance has been considerably improved and even beyond the reliability level of the previous generation of the sensor, which makes it more steady in severe conditions. Each sensing unit had been carefully calibrated and evaluated. Due to the improvement and miniaturization of the sensors, it is more cost-effective.
2. Application Scenarios
The AHT21B is a kind of sensor of humidity and temperature with digital I²C output. It can be applied to HVAC, dehumidifier, testing and inspection equipment, consumer products,
automobiles, automatic control, data loggers, weather stations, home appliances, humidity control, medical, and other application fields which need to detect and control the temperature
and humidity.
