{"product_id":"ldr-light-dependent-resistor-5-pack-discontinued","title":"LDR - Light Dependent Resistor (5 Pack) [Discontinued]","description":"\u003cp\u003eLight Dependent Resistors (LDRs) are little light sensors, and this is a BIG \u003cstrong\u003epack of 5\u003c\/strong\u003e of them! As the squiggly face is exposed to more light, the resistance goes down. When it's light, the resistance is about 5-10K ohms, when dark it goes up to 200K ohms.\u003c\/p\u003e\n\u003cp\u003eThese are the same KLDRs we use in our popular Edukit #2 Sensors.\u003c\/p\u003e\n\u003cp\u003eTo use, connect one side of the photocell (either one, it's symmetric) to power (for example 5V) and the other side to your microcontroller's analogue input pin. Then connect a 10K pull-down resistor from that analogue pin to ground. The voltage on the pin will be 2.5V or higher when it's light out, and near ground when it's dark.\u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e5mm Diameter\u003c\/li\u003e\n\u003cli\u003eResistance \u003cstrong\u003eDecreases\u003c\/strong\u003e as the Light on the Device \u003cstrong\u003eIncreases\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eDark resistance: 1M ohm\u003c\/li\u003e\n\u003cli\u003eResistance @ 10 Lux: 10-20k ohm\u003c\/li\u003e\n\u003cli\u003eResistance @ 100 Lux: 2-4k ohm\u003c\/li\u003e\n\u003cli\u003eMax. voltage: 150V peak AC or DC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePower dissipation: 100mW\u003c\/li\u003e\n\u003cli\u003eLead pitch: 3mm\u003c\/li\u003e\n\u003cli\u003eOperating temperature: –30°C to +70°C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":51290378502180,"sku":"jzy1787258081335","price":1.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/0729\/3732\/files\/ldr---light-dependent-resistor-5-pack-discontinued_1.jpg?v=1787258085","url":"https:\/\/www.cozyharvest.shop\/products\/ldr-light-dependent-resistor-5-pack-discontinued","provider":"My Store","version":"1.0","type":"link"}
