SENS-57 No Contact Digital IR Thermometer Sensor Module MLX90614ESF.
This little breakout board allows users to interface the famous MLX90614ESF IR thermometer component to any Arduino microcontroller without the need for adding resistors and capacitors onto a breadboard. You will have a four pin header that is supplied with the device that can be soldered onto the breakout board. Connect only four wires and plug straight into a Arduino microcontroller and start reading temperatures without having to physically touch them. All digital readings will be sent to your serial monitor on the Arduino software. It makes for a neat and useful little sensor to have around. This device can operate at 5v or 3.3v.
