Far Infrared Sensor PAF9701 From PIXART
Detects Far-Infrared Heat Radiation
PIXART's FIR (Far Infrared) sensing technology mainly detects far-infrared heat radiation with a wavelength in the range of 5~15µm. By converting energy into temperature through its algorithm, the FIR sensor is able to measure the temperature of objects contactless, making it suitable for a wide variety of day-to-day temperature sensing applications.
The PAF9701C1 is an 8x8 pixel low-power infrared (IR) thermal array sensor with integrated temperature computation function.
It measures a target object’s temperature (To) without direct contact the object. The object temperature converted from the voltage of the thermal array sensor and ambient temperature Sensor (Ta). Both temperatures will be calibrate with built-in calibration coefficients, which stored in the internal memory.

The chip supports one-shot operation and four continuous operation modes with different report rate. It offers three alert modes based on low power and application requirements. The low power consumption advantage makes this thermal array sensor is ideal for battery-operated cordless applications.
It measures the temperature of an object (To) without being in direct contact with it. The object temperature is calculated from the voltage of the thermal array sensor and the ambient temperature of the sensor (Ta). Both temperatures are determined with calibration coefficients stored in the integrated memory. The chip supports one-shot operation and four continuous operation modes with different report rates. It has three different alarm modes and can meet most application requirements due to its low power consumption. This thermal array sensor is ideally suited for battery-powered wireless applications.
Example Applications:
- Non-Contact Object temperature sensing
- Smart Appliance-Non-contact temperature monitor
- Temperature feedback control application
- Human detection
