This sensor features an infrared motion and presence detection sensor with an operating wavelength between 5µm and 20µm. This Mini-sized breakout board is only 0.5in. by 1in. big and has been equipped with two I2C Qwiic connectors to make interfacing with the STHS34PF80 a bit easier. It’s part of SparkFun’s \u003ca href=\"\/nl\/search?q=stemma+qt+cable\u0026amp;narrow_by=\u0026amp;sort_by=relevency\u0026amp;page=1\"\u003eQwiic connect system\u003c\/a\u003e, so you won’t have to do any soldering to figure out how things are oriented. However, we still have broken out 0.1in.-spaced pins if you prefer to use a breadboard.\u003c\/p\u003e\n\u003cp\u003eThe STHS34PF80 sensor is designed to measure an object's precise black-body radiation (as described by Plank's law) and monitor ambient temperature conditions within its 80° field of view. The sensor comprises a matrix of floating vacuum thermal transistors MOS split into two parts, one exposed to IR radiation and the other 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 30Hz and an available single-shot, 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 Mini 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: 1.0in. x 0.5in.\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\u003eTwo 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 25cm² 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-mini.pdf?_gl=1*98gmji*_ga*MTc5Njk2NDM5My4xNzAyOTAyMTkw*_ga_T369JS7J9N*MTcwMjkxMzcxOC4zLjEuMTcwMjkxMzcyNy41MS4wLjA.\"\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-mini.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-mini.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 Info Page\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Qwiic_Human_Presence_Sensor-STHS34PF80\"\u003eGitHub Hardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":50847551389969,"sku":"SEN-23253","price":15.2,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic-sparkfun-sen-23253-41327173271747.jpg?v=1735215353","url":"https:\/\/abcd3032.myshopify.com\/nl\/products\/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic","provider":"Tayyab Zak","version":"1.0","type":"link"}
