Usage

The module contains the class Tsl2561 and all the asynchroneous methods are native promise based

const Tsl2561 = require("ada-tsl2561");

let sensor = new Tsl2561();

await sensor.init(1);

let enabled = await sensor.isEnabled();
if (!enabled) await sensor.enable();

let broadband = await sensor.getBroadband();
let infrared = await sensor.getInfrared();
let lux = await sensor.getLux();

console.log(
    `Measure : Broadband ${broadband}, Infrared ${infrared}, Lux ${lux}`
);

API

Tsl2561 Class

The main class of the module representing a sensor

init(busNumber,[address])
