Description of product: Sensor of temperature and humidity DHT22 (AM2302) - module + cables
The module includes a popular sensor for measuring temperature and humidity. On the board are also, required for proper operation of the system: a resistor and a capacitor to filter the supply voltage. The sensor can be controlled using a microcontroller or any commissioning set, for example, Arduino. Before using, you need to see the documentation.

The product is compatible with Arduino Library and connection diagram with Arduino can be found on this address. User manual can be found onour website. |
Pins are popular goldpin connectors (2.54 mm pitch) for connecting the sensor via wires or to directly attach to the breadboard. The set includes three colorful wires.
Connection example
The system contains passive components necessary for the proper operation of the sensor. The module is sufficient to connect via wires, to any microcontroller in the following way:
- VCC ( + ) - supply voltage from the range: 3 V to 5.5 V
- GND ( - ) - the ground of the system
- OUT- digital output connected to the input of the microcontroller
