The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02☌. The sensor uses IR sensitive thermopile detector chip and the signal conditioning ASIC integrated into a single chip. The MLX90614 is an infrared thermometer for non-contact temperature measurements capable of measuring temperature between -70 to 380☌. MLX90614 Contactless Infrared Temperature Sensor The components purchase link is given as well.

The MLX90614 Sensor requires some calibration in Arduino Code which we will learn in this post.Īll the components that you need for this project can be ordered online from the Amazon. Due to COVID-19, the demand for this sensor has increased within the last few months. MLX90614 can also be used as an infrared thermometer for measuring the body temperature. You can even use this sensor for laboratory purposes, i.e. You can use MLX90614 to measure the temperature of a hot object like machines, flames, hot iron, device CPU.

The refresh rate and sensitivity of MLX90614 are very high that it can give the reading within a fraction of a second.

In this project we will interface MLX90614 with Arduino Board and use the laser diode to point the sensor to a particular object. The MLX90614 sensor uses contactless temperature sensing to measure the temperature data without any physical contact to particular surface. For this, you can use the MLX90614 infrared thermometer from Melexis for this project. We need some sensors that can measure the temperature without any contact & sensing the temperature through IR is the best method. But if you wish to measure the temperature of a very hot body like a flame or hot iron, you can’t rely on these sensors. However, these temperature sensors only sense the temperature when the heat is applied to them directly on their surface. Earlier we used temperature Sensors like DS18B20, LM35 & MAX6675. You can display the temperature reading on SSD1306 0.96″ OLED Display.

Now your 1602 LCD will show the temperature of the object which is in front of MLX90614 sensor. Step 3) Download your sample sketch from In IDE top menu->Sketch ->Include Library ->Manager Libraries, then in search keywords “Adafruit_MLX90614”, you will find Adafruit_MLX90614 library, click “Install” to load this library into your IDE. Zip library, add above file into IDE library. Then in IDE top menu->Sketch ->Include Library -> Add. Step 1) Download LiquidCrystal I2C library from In UNO, A4 is also SDA pin and A5 also is SCL pin. In UNO and MEGA2560 board, SCL is leftmost pin in the digital pin rows (the fourth pin left of D13), and SDA is just beside SCL pin (third pin left of D13). MLX90614 Infrared temperature sensor and I2C 16×2 LCD all exchange data with Arduino through I2C bus.
