The 7Semi Human Presence and Motion Sensor is designed around the STHS34PF80 infrared sensing device for reliable presence and motion detection within an 80 degree field of view. It supports up to 4 meter sensing distance, making it suitable for smart lighting, security, and occupancy monitoring systems.
This compact board uses a 6 pin 2.5 mm SMD JST XH side entry header for simple integration with microcontrollers. It provides stable operation under varied lighting conditions due to its 5 to 20 micrometer optical band pass filter, factory calibration, and built in algorithms capable of identifying both stationary and moving objects.

• High sensitivity detection Human presence and motion detection up to 4 meters
• Wide field of view 80 degree coverage
• Stable performance Integrated silicon IR filter for consistent readings
• Smart algorithms Able to differentiate stationary and moving targets
• Low power design Suitable for battery powered IoT devices
• Easy integration 6 pin header with 3V3 GND SCL SDA CS INT
• Factory calibrated Ensures accurate thermal and infrared measurements
Applications
• Presence and proximity sensing
