Far infrared (FIR) imaging is becoming an important aspect of many market segments including:
- automotive – pedestrian detection, close range blind spot detection and occupancy classification
- smart buildings -thermal measurement and occupancy functions
- homes - smarter microwave and conventional ovens
- energy efficiency – to detect heat losses and illustrate the need for improvements
- industrial – smart process controls and thermal testing
To address these applications, Melexis has introduced the MLX90620 FIRray sensing device. The thermopile sensor array produces a map of heat values for the target area in real time. The 16 x 4 element covers a temperature range of -20°C to 300°C.
Limiting the imaging to 64 pixels in 2D helps the sensor to address high volume, low cost applications. Integration of an amplifier and ADC in every pixel allows the array to offer an adjustable frame rate from 0.5 Hz to 64 Hz. Operation in the 0°C to 50°Crange delivers accuracy levels of ±1.5°C.
