SHT1x Humidity and Temperature Sensor SKU DFR0066

Introduction

This module uses the SHT1x sensor. The SHT1x chip is individually calibrated in a precision humidity chamber. The calibration coefficients are programmed into an OTP memory on the chip. These coefficients are used to internally calibrate the signals from the sensors. The 2-wire serial interface and internal voltage regulation allows for easy and fast system integration. The tiny size and low power consumption makes SHT1x the ultimate choice for even the most demanding applications.

//Version 1.0

#include <SHT1x.h>

// Specify data and clock connections and instantiate SHT1x object
#define dataPin  10
#define clockPin 11
SHT1x sht1x(dataPin, clockPin);

void setup()
{

   Serial.println("Starting up");
}

void loop()
{
  float temp_c;
  float temp_f;
  float humidity;

  // Read values from the sensor
  temp_c = sht1x.readTemperatureC();
  temp_f = sht1x.readTemperatureF();
  humidity = sht1x.readHumidity();

  // Print the values to the serial port
  Serial.print("Temperature: ");
  Serial.print(temp_c, DEC);
  Serial.print("C / ");
  Serial.print(temp_f, DEC);
  Serial.print("F. Humidity: ");
  Serial.print(humidity);
  Serial.println("%");
