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 Qwiic connect system, 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.\n\nThe 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.\n\nThe 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.\n\n\n\nThe SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.\n\n\n\n Get Started with the SparkFun Qwiic Mini Human Presence and Motion Sensor\n\n\nFeatures:\n\nBreakout Board\n\n\nDimensions: 1.0in. x 0.5in.\nTwo Qwiic Connectors\n\n\nI2C Address (7-bit): 0x5A (Default)\n\n\n\nTwo Mounting Holes:\n\n\n4-40 screw compatible\n\n\nSix PTH Pins\n\n\n\n3V3, GND, SCL, SDA, CS, INT\n\n\n\nPower LED (Red)\n\n\n\nSTHS34PF80 Features\n\n\nVoltage Range: 1.7 to 3.6V\n\n\nCurrent Draw: 10µA\n\n\nInterfaces: I²C or SPI\nOptical wavelength: 5 to 20µm\nRange: 4m (objects 70 x 25cm² in size)\n\nBuilt-in Detection Algorithms:\n\n\nIdentify stationary objects\nDistinguish between stationary and moving objects\n\n\nField of View: 80°\nOutput Data Rate: 0.25 to 30Hz\nIR sensitivity: 2000 LSB/°C\nRMS noise: 25 LSBrms\n\nOperating Temperature: -40 to 85°C (default gain mode)\n\nSensor accuracy: ±0.3°C (local)\n\nOne-shot mode\nFactory calibrated\n\n\nDocuments:\n\n\nSchematic\nEagle Files\nBoard Dimensions\n\nHookup Guide\n\n\nArduino Library\n\n\nComponent Datasheets:\n\n\n\nSTHS34PF805 Product Page\n\n\nSTHS34PF805 Datasheet\n\n\n\n\nQwiic Info Page\nGitHub Hardware Repo\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1222,"title":"Default Title","sku":"SF-SEN-23253","mpn":"SEN-23253","price":40.81,"on_sale":false,"in_stock":true,"available_quantity":156,"option1":"Default Title"}]}
