#include <Wire.h>
#include "Adafruit_MCP9808.h"

// Create the MCP9808 temperature sensor object
Adafruit_MCP9808 tempsensor = Adafruit_MCP9808();

void setup() {
  Serial.println("MCP9808 demo by Robojax");
  // Make sure the sensor is found, you can also pass in a different i2c
  // address with tempsensor.begin(0x19) for example
  if (!tempsensor.begin()) {
    Serial.println("Couldn't find MCP9808!");
    while (1);

void loop() {
  //Serial.println("wake up MCP9808.... "); // wake up MCP9808 - power consumption ~200 mikro Ampere
  //tempsensor.wake();   // wake up, ready to read!

  // Read and print out the temperature, then convert to *F
  float c = tempsensor.readTempC();
  float f = c * 9.0 / 5.0 + 32;
  Serial.print("Temp: "); Serial.print(c); Serial.print("*C	"); 
  Serial.print(f); Serial.println("*F");
  //Serial.println("Shutdown MCP9808.... ");
  //tempsensor.shutdown(); // shutdown MCP9808 - power consumption ~0.1 micro Ampere
}// loop end
