To connect the WHADDA WPSE345 CM2302-DHT22 Temperature and Humidity Sensor Module to an Arduino UNO board, follow these steps:
1. Connect the VCC pin of the sensor module to the 5V pin on the Arduino UNO.
2. Connect the GND pin of the sensor module to the GND pin on the Arduino UNO.
3. Connect the DAT pin of the sensor module to any digital pin on the Arduino UNO (e.g., pin 2).
Please refer to the "Connection" section in the user manual for a visual representation of the connections.
Note: Make sure to download and add the DHT library to the Arduino IDE before using the sensor module. You can find the library on the manufacturer's website.
Once the connections are made, you can use the provided sample sketch in the user manual to read temperature and humidity data from the sensor module. The sample sketch includes instructions on how to read and print the data to the serial monitor.
If you encounter any issues or need further assistance, please refer to the complete user manual for more detailed instructions and troubleshooting tips.
