The resistance of a photo-resistor decreases with increasing incident light intensity and vice versa. The sensor exhibits photoconductivity which makes it possible to detect the light varies based on voltage and use an AD (Analog to digital converter) to convert the digital data.\u003c\/p\u003e\n\u003cp\u003eWe added some extra work to strengthen the circuit, a Dual Differential Comparators LM393, compares the differential voltage between the photo-resistor and the varistor. It could offer a larger and more accurate range of light intensity.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e10K adjustable resistor\u003c\/li\u003e\n\u003cli\u003eSoftware Development Platform: Arduino, UIFlow (Blocky,Python)\u003c\/li\u003e\n\u003cli\u003eTwo Lego-compatible holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable width=\"272\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"156\"\u003e\u003cstrong\u003eResources\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"116\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdjustable resistance\u003c\/td\u003e\n\u003ctd\u003e10K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet weight\u003c\/td\u003e\n\u003ctd\u003e4g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGross weight\u003c\/td\u003e\n\u003ctd\u003e17g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Size\u003c\/td\u003e\n\u003ctd\u003e32x24x8xmm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Size\u003c\/td\u003e\n\u003ctd\u003e67x53x12mm\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\/light\"\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 Light Sensor Unit\u003c\/li\u003e\n\u003cli\u003e1x Grove Cable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M5Stack","offers":[{"title":"Default Title","offer_id":50847654019345,"sku":"U021","price":3.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/light-sensor-unit-with-photo-resistance-m5stack-u021-40630998073539.jpg?v=1735217407","url":"https:\/\/abcd3032.myshopify.com\/ru\/products\/light-sensor-unit-with-photo-resistance","provider":"Tayyab Zak","version":"1.0","type":"link"}
