Description
The module includes a popular sensor for measuring temperature and air 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 implementation set, for example,Arduino. Before using, you need to see thedocumentation.
|
The product is compatible with Arduino The manufacturer provides a sample program forArduino. User manual can be founnd onour website. |
Leads are the populargoldpin connectors(2.54 mm pitch) for connecting the sensor viawiresor to connect directly to breadboard. The kit includes a connecting cable with female ends.
Connection example
The system contains everypassive component necessary for the proper operation of the sensor. The module has to be only connected via wires to any microcontroller in the following way:
- VCC ( + ) -supply voltage in range from 3.3 V to 5.5 V
- GND ( - ) - the mass of the system
- DOUT- digital output connected to the input of the microcontroller
