{"product_id":"tmos-pir-unit","title":"TMOS PIR Unit","description":"\u003cp\u003eThe TMOS PIR Unit is a high-sensitivity infrared sensor for detecting presence and motion. Using the STHS34PF80 chip, it communicates with M5 devices via I2C (default address: 0x5A). The sensor can monitor ambient temperature, and detect human presence and motion.\u003c\/p\u003e\n\u003cp\u003eIt can differentiate between stationary and moving objects and has an 80-degree field of view, providing a broad detection range. The unit also supports adjustable sampling frequency and gain modes, allowing it to adapt to various projects. It is ideal for use in alarm systems, smart lighting, and occupancy detection.\u003c\/p\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003e1. Set the TMOS gain mode:\u003cbr\u003eDefault gain mode: High sensitivity, but it may cause sensor saturation. Saturation can lead to delayed updates of the motion\/presence detection flag;\u003cbr\u003eWide mode: Shorter detection distance, but avoids sensor saturation.\u003cbr\u003e2. Sensitivity to temperature differences: The output signal of the TMOS sensor is very sensitive to the temperature difference between the sensor's own ambient temperature and the ambient temperature of the measurement room. This temperature difference can affect the sensor's measurement.\u003cbr\u003e3. Power-down mode settings: When the device is in power-down mode, the register resets to its default value each time the device is started or restarted. The calibration temperature needs to be reset. Therefore, if the application requires covering a wide operating temperature range and the temperature difference between the room and the sensor's thermal coupling environment, you need to set the wide mode when the device starts.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-sensitivity infrared detection\u003c\/li\u003e\n\u003cli\u003eWide field of view\u003c\/li\u003e\n\u003cli\u003ePresence and motion detection\u003c\/li\u003e\n\u003cli\u003eI2C communication (0x5A)\u003c\/li\u003e\n\u003cli\u003eProgrammable output data rate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable width=\"467\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"245\"\u003eSensor\u003c\/td\u003e\n\u003ctd width=\"222\"\u003eSTHS34PF80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI2C Communication Address\u003c\/td\u003e\n\u003ctd\u003e0x5A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Distance\u003c\/td\u003e\n\u003ctd\u003eOver 2 meters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Detection Size\u003c\/td\u003e\n\u003ctd\u003e70 x 25 cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField of View (FOV)\u003c\/td\u003e\n\u003ctd\u003e80°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProgrammable Output Data Rate\u003c\/td\u003e\n\u003ctd\u003e0.25 Hz to 30 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInfrared Wavelength\u003c\/td\u003e\n\u003ctd\u003e5 to 20µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInfrared Sensitivity\u003c\/td\u003e\n\u003ctd\u003e2000 LSB\/°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.3°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain Modes\u003c\/td\u003e\n\u003ctd\u003eDefault gain mode, wide mode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Dimensions\u003c\/td\u003e\n\u003ctd\u003e32 x 24 x 8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Dimensions\u003c\/td\u003e\n\u003ctd\u003e136 x 92 x 13mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e4.4g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Weight\u003c\/td\u003e\n\u003ctd\u003e10g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.m5stack.com\/en\/unit\/UNIT-TMOS%20PIR\"\u003eProduct Wiki\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x TMOS PIR Unit\u003c\/li\u003e\n\u003cli\u003e1x HY2.0 4-pin Grove cable (20cm)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M5Stack","offers":[{"title":"Default Title","offer_id":50847259328785,"sku":"U185","price":6.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/tmos-pir-unit-m5stack-u185-43044126884035.jpg?v=1735209374","url":"https:\/\/abcd3032.myshopify.com\/hi\/products\/tmos-pir-unit","provider":"Tayyab Zak","version":"1.0","type":"link"}
