sensor-htu21d

Synopsis

Library to read out a HTU21d humidity/temperature sensor connected via I2C. It depends on the "i2c-bus" library and is tested on a Raspberry Pi 3.

Code Example

let Htu21d = require('./htu21d.js');
let htu = new Htu21d(1, 1000);
htu.start();
 
htu.on('readout-complete', (data) => {
  console.log(data);    // e.g. { temperature: 26.39, humidity: 16.45 }
});
 
htu.on('error', (error) => {
  console.log(error);
});

Motivation

The HTU21d is capable of measuring humidity with a resolution of 0.04 %rel and temperature with a resolution of 0.01 °C.

Installation

npm install sensor-htu21d
