veml6070-sensor

 

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
}
