Template: TVOC Sensor Arduino Use

Working with Arduino

• The IO level of the Arduino development board must be 3.3V. If a 5V IO level is used, level conversion is required, otherwise the sensor will be damaged
• To use waveshare R3/R4, you need to set the following jumper cap to 3.3V before you can use it

• 

  Arduino UNO R3

• 

  Arduino UNO R4

• 

  Arduino UNO R4 WIFI

• For Arduino environment setup and basic usage, please refer to this R4 link, R3 is installed by default.
• After setting up the environment, you can connect the sensor and download the Demo

Arduino Demos

Hardware Connection

• Refer to the following diagram for connection:

• 

  Arduino UNO R3

• 

  Arduino UNO R4

Run Demo

• Go to TVOC_Sensor_Demo\Arduino\TVOC_UART_Demo and double-click on the TVOC_UART_Demo.ino file
• Select development board:

• 

  Arduino UNO R3

• 

  Arduino UNO R4

• Select the port of the development board, and then compile and upload it
• After the upload is completed, open the serial port monitor, and the relevant information will be output
