Mounted on a breakout board with two types of pinsġ0k Pull up resistors for the I2C interface with optional solder jumpersįactory calibrated in wide temperature range: They can be disabled, as usual, by using the solder jumpers on the back of the board.
We’ve included in our design pull-up resistors on the I2C lines as customary. This breakout board makes it easy to connect this sensor to your microcontroller board or single-board computer such as Arduino, ESP8266, ESP32, BeagleBone or Raspberry Pi! The four pins correspond to power ( VCC, GND) and I2C communication ( SDA, SCL). That’s 128 times more precise than the ADC on the ATmega328 microcontroller onboard an Arduino UNO, and implies that the MLX90614 infrared temperature sensor can distinguish temperatures between 25✬ and 25.02✬ without even coming in contact with the object! Want to read temperature without touching the object you’re measuring? Then the MLX90614 IR Thermometer is the sensor for you! By detecting the InfraRed (IR) light emitted by an object, The MLX90614 can read temperatures between –95 and 720✯ (–70 and 382.2☌) with a whopping 17-bit resolution. This breakout board provides a convenient way to start using the fantastic MLX90614 module, a high precision, small size, single-zone IR thermometer ( temperature sensor)! MLX90614 includes a low noise amplifier, a 17-bit ADC, and a powerful DSP module in a TO-39 through-hole package.Connect the two-wire interface (I2C) to your Arduino, ESP8266, ESP32, Raspberry Pi, etc.

The MLX90614 Infrared Temperature sensor is quite different from the rest of the sensors, as it needs to physical contact with the object to measure the temperature.Īs I am using this sensor for the first time, so I will cover the extreme basics including the MLX90614 Library downloading, MLX90614 basic connection with Arduino, and then how to write a very basic program to display the temperature on the Serial Monitor.Īfter cover the very basic things, then I will display the temperature on a display. I have been using different temperature sensor “ DHT11, DS18B20, LM35, Thermistors, MAX6675 Thermocouple, etc” with Arduino, ESP32, and Nodemcu ESP8266 for quite a long time. MLX90614 Non-Contact Infrared Temperature Sensor with Arduino– In this article, you will learn how to use the MLX90614 Non-Contact Infrared Temperature Sensor with Arduino.

They each have a 64 bit unique address (which you need to "discover"). The nice thing about 1-Wire and this component is you can put a bunch of these all on just one pin. For whatever reason, I was unable to get the AVR internal pull up to work with it. I threw a 10k in there, but I have seen lower values used. A pull up resistor is required between the white data line and red power line. The description seems to indicate that "no external components are needed" and you just need to wire it up and go. This was my first actual experience with 1-Wire. I would much rather suggest this library as it also supports multiple sensors (and does not try to use some LCD display): Īlso, the standard One Wire library in the Arduino Library Manger is required.

The example code SparkFun supplies is not the best, but with a bit of tweaking it could work okay.
