The Waveshare MLX90614 module integrates the Melexis MLX90614 infrared thermopile sensor in a compact breakout board. It performs non-contact temperature measurement by detecting the infrared radiation emitted from an object’s surface. The sensor combines an IR-sensitive thermopile detector, a low-noise amplifier, a 17-bit ADC, and a powerful DSP unit within a single TO-39 package, enabling high-resolution readings with a resolution of 0.02°C.
The module is factory-calibrated for a broad object temperature range and includes built-in signal conditioning. It provides digital output via both I2C (SMBus) and configurable PWM, allowing for seamless integration with 3.3V or 5V logic microcontrollers without external level shifters. Its 35° field of view makes it suitable for measuring the average temperature over an area, not just a single point.
