sht31-node

A simple Node.js library to read temperature and humidity values from the SHT31/SHT35 sensors.

This library relies on this datasheet.

Requirements

• A Raspberry Pi
• I2C must be enabled
• SHT31 or SHT35 sensor Adafruit
• Node.js v7.6 or newer

Installation

# Run this in your favourite terminal
npm i sht31-node

Usage

Simply require and instantiate the package as a class. The readSensorData method returns a promise.

const { SHT31 } = require('sht31-node')

// Parameters are unecessary when using a B+, A+, Zero, Zero W, Pi 2, or Pi 3
const sht31 = new SHT31()

sht31.readSensorData().then(data => {
    // Temperature in Fahrenheit
    const temperature = Math.round(data.temperature * 1.8 + 32)
    const humidity = Math.round(data.humidity)
    
  console.log(`The temperature is: ${temperature}°F`)
  console.log(`The Humidity is: ${humidity}%`)
}).catch(console.log)
