Description
Digital temperature and humidity sensor module built around the Aosong DHT22 (AM2302) sensor. It measures relative humidity from 0 to 100% RH (±2% accuracy) and temperature from -40 to 80°C (±0.5°C accuracy), with a single-bus digital output that talks to any microcontroller over one data pin.
Works on 3-5.5V (5V commonly used), draws ultra-low power, and is factory calibrated with a fully digital output, no additional components needed. Compatible with Arduino. Size 28.2 x 13.1 x 5.5mm with a 155mm line. 4-pin interface: + (positive), – (ground), and Out (data to the microcontroller IO pin).
Use it for weather stations, greenhouse monitors, 3D printer enclosure temperature control, and any Arduino or ESP32 project that needs temperature and humidity. I check every order before it ships. Ships from NY, USA.
