Infrared motion sensor detects people at a range of up to 4 m

The STMicroelectronics STHS34PF80 infrared motion and heat-detection sensor is sensitive enough to detect the presence of a person at a distance of up to 4 metres without the need for a lens.

The uncooled STHS34PF80 is factory-calibrated to provide accurate sensor measurements. Raw optical sensor outputs are digitally processed by the STHS34PF80’s embedded ASIC, which can be programmed to monitor for motion, presence, or over-temperature. The sensor is capable of detecting stationary objects, and of distinguishing between stationary and moving objects.

The output data rate is configurable in a range between 0.25 Hz and 30 Hz. The STHS34PF80 is housed in a 10-lead LGA package measuring 3.2 mm x 4.2 mm x 1.5 mm. The package is compatible with surface-mount assembly processes.
