HTU21D

A Library to add support of HTU21D temperature and humidity sensor to Particle core (Formerly Spark Core).

Usage

Before your setup function

#include "HTU21D.h"
HTU21D htu = HTU21D();

In your setup function

    // HT21D sensor setup
    while(! htu.begin()){
        Serial.println("Couldnt find HTU21D");
        delay(1000);
    }

In your loop you can now get values like that

    temperature = htu.readTemperature();
    humidity = htu.readHumidity();

Options

Resolution

The sensor offers 2 configurations: Maximum resolution : 12bits resolution for Relative humidity and 14bits for temperature or 11bit resolution for both temperature and relative humidity

    // Set maximum resolution
    htu.setResolution(HTU21D_RES_MAX);

    // Set 11bits resolution
    htu.setResolution(HTU21D_RES_11BITS);
