## Description

Digital module for precise temperature and humidity measurement, ideal for Arduino projects and other development boards. It operates at 3.3V or 5V, uses original sensor for high stability and accuracy, offers reading on a single digital pin and includes mounting hole for quick integration into cases and panels.
AM2302 temperature and humidity sensor module, the module version of the DHT22 sensor. The product is compatible with Arduino and other development boards. It can be used with both 3.3V and 5V.
This model uses original sensors, not clones, and offers high measurement accuracy.
It uses a capacitive sensor to measure humidity and a thermistor type sensor to measure temperature. The module is digital, which is why it does not use analog pins. It only needs the DHT22 library, power supply and connecting the digital output to one of the digital inputs of the development board.
The presence of the mounting hole on the plate is also very useful.
