    Node.js versions NPM version

    Welcome to veml6070-sensor, a Node.js I2C module for the Vishay Semiconductors VEML6070 UVA Light Sensor. Adafruit sells a VEML6070 breakout board and here is the datasheet.

    This module uses i2c-bus which should provide access with Node.js on Linux boards like the Raspberry Pi Zero, 1, 2, or 3, BeagleBone, BeagleBone Black, or Intel Edison.

    Since veml6070-sensor needs to talk directly to the I2C bus and requires access to /dev/i2c, you will typically need run Node with elevated privileges or add your user account to the i2c group: $ sudo adduser $USER i2c

    Example Code

    const VEML6070 = require('veml6070-sensor');
    
    // VEML6070 constructor options object is optional, i2cBusNo defaults to 1
    //
    const veml6070 = new VEML6070( {i2cBusNo : 1} );
    
    const readSensorData = () => {
      veml6070.readSensorData()
        .then((data) => {
          console.log(`data = ${JSON.stringify(data, null, 2)}`);
          setTimeout(readSensorData, 1000);
        })
        .catch((err) => {
          console.log(`VEML6070 read error: ${err}`);
          setTimeout(readSensorData, 2000);
        });
    };
    
    // VEML6070 init options object is optional, integrationTime defaults to VEML6070.VEML6070_INTEGRATION_TIME_1_T()
    //
    veml6070.init({integrationTime : VEML6070.VEML6070_INTEGRATION_TIME_1_T()})
      .then((result) => readSensorData())
      .catch((err) => console.error(`VEML6070 init failed: ${err} `));
    

    Example Output

    > sudo node example.js
    data = {
      "uv": 3839
    }
    

    Example Wiring

    For an example of I2C setup on a Raspberry Pi, take a look at my pi-weather-station project.
