  Grove - AHT20 I2C Industrial Grade Temperature and Humidity Sensor is 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.
   
  The output is I2C protocol with Grove interface. We have developed more than 400 Grove modules covering a wide range of applications that can meet various needs. Plug and play, easy to get started!
