Description
The module includes a popular sensor for measuring temperature and humidity. On the board are also: a resistor and a capacitor to filter the supply voltage - they are required for proper operation of the system. The sensor can be controlled using a microcontroller or any development kit, for example,Arduino. Before using, you need to check out thedocumentation.
The product is compatible with Arduino The manufacturer provides a sample program forArduino. User manual can be found onour website. |
The kit includes the connection cable with the Grove contact.
Connection example
The system contains every passive component necessary for the proper operation of the sensor. The module has to be connected using the wires, to any microcontroller in the following way:
- VCC ( + )supply voltage in the range: from 3.3 V to 5.5 V
- GND ( - ) the ground of the system
- NC- not connected.
- SIG- digital output connected to the input of the microcontroller
Connection example
- VCC ( + ): supply voltage in the range: from 3.3 V to 5.5 V
- GND ( - ): the ground of the system
