Introduction
This is a calibrated digital temperature and humidity sensor for detecting ambient temperature and humidity, using DHT22 (AM2302), standard single bus interface.
Compared with DHT11, it has higher precision and larger range.
Can be used with the ESP-01/ESP-01S WIFI module and can replace the SHT11 SHT15.
