Grove AHT20 I2C Industrial Grade Temperature and Humidity Sensor are packaged in a dual-row flat lead-free chip package, suitable for reflow soldering. The AHT20 is equipped with a newly designed ASIC chip: an improved MEMS semiconductor capacitive humidity sensor and a standard on-chip temperature sensor.
Compared with previous generation temperature and humidity sensors such as Grove-Temperature & Humidity Sensor Pro (AM2302/DHT22), AHT20 has a more stable performance in harsh environments. In fact, AHT20 is suitable for most industrial scenarios.
