Overview

The MLX90614ESF-BAA-000-TU is an automotive-grade infrared thermometer designed for non-contact temperature measurement. It integrates an IR sensitive thermopile detector chip and a signal conditioning ASIC into a single TO-39 metal can package, providing high-accuracy digital output over an SMBus or PWM interface.

Why Choose This Part

This sensor features a high-resolution 17-bit ADC and comes factory calibrated for high precision across a wide temperature range. It includes a low-power sleep mode consuming only 2uA and is housed in a robust TO-39 package for harsh environment reliability.

Applications

Non-Contact Temperature Sensing
Ideal for measuring surface temperatures of moving parts or high-voltage components where physical contact is impossible.
HVAC Thermal Comfort
Used in mobile air conditioning and building automation to monitor zone temperatures and adjust climate control systems.
Industrial Process Control
Monitoring temperature-sensitive manufacturing processes without contaminating the product or damaging the sensor.
Intrusion Detection
High-sensitivity IR detection for security and movement monitoring systems.

Getting Started

Integrate this sensor using the SMBus interface, which is compatible with most I2C peripherals found on MCUs like the STM32 or AVR. Engineers should ensure the supply voltage remains between 2.6V and 3.6V and utilize the available PWM output for simple thermal threshold monitoring without a complex software stack.
