MLX90614 non-contact temperature sensor
Joy-IT SEN-IR-TEMP is a module with an MLX90614 infrared sensor that measures object temperature without contact from -70 °C to 380 °C and sends the result over I2C. The sensor also measures ambient temperature from -40 °C to 125 °C, and in the range from 0 °C to 50 °C it has an accuracy of 0.5 °C. You power the module with a voltage from 3.3 V to 5 V and it draws at most 2.5 mA.
- Reading of object and ambient temperature from one sensor
- I2C interface with a library for Arduino
- Small module measuring 24 x 12 x 8 mm

Good choice for you?
Good choice if:
- you want to measure temperature without touching the object, for example a hot surface
- you are building a thermometer or a circuit that controls the temperature of a component
- you work with an Arduino or Raspberry Pi over the I2C bus
Consider another option if:
- you need a ready-made meter with a display, because this is a module to connect to a microcontroller
- you measure temperatures above 380 °C, because that is the upper limit of this sensor
Fun fact
Two measurements from one sensor
The MLX90614 measures at the same time the temperature of the object it is pointed at and the ambient temperature. In the Joy-IT examples, the program for the Raspberry Pi reads both values over the I2C bus.

Frequently asked questions
How do I connect it to an Arduino?
You connect the module to the Arduino through the SDA and SCL pins of the I2C bus, and you connect the VIN supply to 5 V. The manufacturer uses the Adafruit MLX90614 library and the mlxtest example.
What range does it measure?
The sensor measures object temperature from -70 °C to 380 °C and ambient temperature from -40 °C to 125 °C. It reaches an accuracy of 0.5 °C in the range from 0 °C to 50 °C.
Does it work with a Raspberry Pi?
Yes, in that case you power the module with 3.3 V and connect it over I2C. The manufacturer provides a Python example with the smbus library.
