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])

Initialize the i2c bus and set the sensor address

• busNumber : The i2c bus number to use
• address : The address of the sensor (default 0x39)

free()

Free the i2c bus

enable()

Enable the sensor

All measures of the sensor are at 0 is not enabled

disable()

Disable the sensor

All measures will be at 0 after disabling the sensor

isEnabled()

Check if the sensor is enabled returning true if the sensor is enabled

getLux()
