MLX90601 family IR thermometer modules provide remote temperature measurement, fully linearized signals, analog voltage output, digital PWM output and SPI interface. They are used in automotive climate control, toasters, microwave ovens and other applications that require temperature control, residential, commercial climate control and occupancy detection, industrial temperature transducer and monitoring applications.
The MLX90601 family consists of IR thermometer modules that offer analog voltage, PWM coded digital and SPI interfaces. All modules are factory calibrated, include an open‑drain relay driver and are built on either rigid PCB or flexible polyamide substrates depending on the variant.
The document contains functional diagrams, electrical specifications, pin‑out tables, calibration details and application notes for automotive, industrial and consumer uses, as well as guidance for SPI interfacing and reliability information.
