The sensor is composed of a matrix of floating vacuum thermal transistors MOS split into two parts, one exposed to IR radiation and the other one shielded. The differential reading between the segments, allows the sensor to remove self-heating effects. The STHS34PF80 also incorporates algorithms to detect and discriminate between stationary and moving objects. These features enable the sensor to work as a human presence and motion sensor in different applications such as alarm systems, anti-intruder systems, smart lighting, and room occupancy.\u003c\/p\u003e\n\u003cp\u003eThe sensor can operate in multiple lighting conditions and is unaffected by visible light or other bands thanks to the 5 to 20µm optical band-pass filter. The STHS34PF80 has output data rates between 0.25 to 30 Hz and an available single-shot, which are accessed through its I²C\/SPI interface.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_Qwiic_Human_Presence_Sensor-STHS34PF80\/introduction\/\"\u003eGet Started with the Sparkfun Qwiic Human Presence and Motion Sensor\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eBreakout Board\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 1\" x 1\"\u003c\/li\u003e\n\u003cli\u003eTwo Qwiic Connectors\n\u003cul\u003e\n\u003cli\u003eI2C Address (7-bit): 0x5A (Default)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eFour Mounting Holes:\n\u003cul\u003e\n\u003cli\u003e4-40 screw compatible\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSix PTH Pins\n\u003cul\u003e\n\u003cli\u003e3V3, GND, SCL, SDA, CS, INT\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003ePower LED (Red)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSTHS34PF80 Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVoltage Range: 1.7 to 3.6V\n\u003cul\u003e\n\u003cli\u003eCurrent Draw: 10µA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eInterfaces: I²C or SPI\u003c\/li\u003e\n\u003cli\u003eOptical wavelength: 5 to 20µm\u003c\/li\u003e\n\u003cli\u003eRange: 4m (objects 70 x 25 cm² in size)\u003c\/li\u003e\n\u003cli\u003eBuilt-in Detection Algorithms:\n\u003cul\u003e\n\u003cli\u003eIdentify stationary objects\u003c\/li\u003e\n\u003cli\u003eDistinguish between stationary and moving objects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eField of View: 80°\u003c\/li\u003e\n\u003cli\u003eOutput Data Rate: 0.25 to 30Hz\u003c\/li\u003e\n\u003cli\u003eIR sensitivity: 2000 LSB\/°C\u003c\/li\u003e\n\u003cli\u003eRMS noise: 25 LSBrms\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40 to 85°C (default gain mode)\u003c\/li\u003e\n\u003cli\u003eSensor accuracy: ±0.3°C (local)\u003c\/li\u003e\n\u003cli\u003eOne-shot mode\u003c\/li\u003e\n\u003cli\u003eFactory Calibrated\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_Qwiic_Human_Presence_Sensor-STHS34PF80\/assets\/board_files\/schematic-1x1.pdf?_gl=1*1hc0556*_ga*MTc5Njk2NDM5My4xNzAyOTAyMTkw*_ga_T369JS7J9N*MTcwMjkwOTM0NC4yLjAuMTcwMjkwOTQzMy42MC4wLjA.\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_Qwiic_Human_Presence_Sensor-STHS34PF80\/assets\/board_files\/eagle_files-1x1.zip\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_Qwiic_Human_Presence_Sensor-STHS34PF80\/assets\/board_files\/dimensions-1x1.pdf\"\u003eBoard Dimensions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_Qwiic_Human_Presence_Sensor-STHS34PF80\"\u003eHookup Guide\u003c\/a\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_STHS34PF80_Arduino_Library\/tree\/main\"\u003eArduino Library\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eComponent Datasheets:\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/www.st.com\/en\/mems-and-sensors\/sths34pf80.html\"\u003eSTHS34PF805 Product Page\u003c\/a\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_Qwiic_Human_Presence_Sensor-STHS34PF80\/assets\/component_documentation\/sths34pf80.pdf\"\u003eSTHS34PF805 Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003eQwiic Ecosystem\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Qwiic_Human_Presence_Sensor-STHS34PF80\"\u003eGitHub Hardware Repository\u003c\/a\u003e'\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":50847547031825,"sku":"SEN-22494","price":14.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic-sparkfun-sen-22494-41334273376451.jpg?v=1735215234","url":"https:\/\/abcd3032.myshopify.com\/nl\/products\/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic","provider":"Tayyab Zak","version":"1.0","type":"link"}
