Infrared Thermometer Gun
The infrared thermometer gun uses an MLX90615 non-contact infrared sensor and an OLED display. Students assemble it and write the code themselves to build a thermometer that shows body or object temperature.

Product features
The Arduino infrared thermometer gun uses an MLX90615 non-contact infrared temperature sensor. The sensor temperature range is -40 to 85 °C and the object temperature range is -40 to 115 °C, with 0.5 °C accuracy within those ranges.
It includes a buzzer for alerts and a 0.96-inch OLED display.
A rechargeable power board with a switch: connect a Micro USB cable to charge the battery without removing the battery or the case.
Clear acrylic case: once assembled, you can see the circuits and components inside, giving it a distinctive maker-style look.
