7Semi Human Presence and Motion Sensor FOV 80deg STHS34PF80 - 4 Meters
The 7Semi Human Presence and Motion Sensor is a compact and intelligent infrared sensing module built around the advanced STHS34PF80 sensor for accurate human presence, motion, and ambient temperature detection. Using precision black-body infrared sensing technology, the module detects both stationary and moving human targets up to 4 metres away without requiring additional optics or lenses.
Designed for smart automation, occupancy sensing, and low-power IoT applications, the module features an 80° field of view and an integrated smart processing engine capable of distinguishing between static and dynamic objects. Its floating thermal transistor architecture minimizes self-heating effects, ensuring stable and reliable detection across varying indoor conditions.
The board includes a 6-pin JST XH 2.5mm connector, onboard I2C/SPI interface support, standard PTH breakout pins, mounting holes, and a power status LED for easy integration into embedded systems, smart lighting, security devices, automation systems, and intelligent occupancy monitoring solutions.
