{"product_id":"ambient-light-sensor-breakout-board-discontinued","title":"Ambient Light Sensor Breakout Board [Discontinued]","description":"\u003cp\u003eThis circuit uses an SFH 320-3\/4-Z phototransistor and provides an analogue signal which gives a representation of the levels of light that are falling on the phototransistor on the board. This is achieved by creating a potential divider using a 2M2 resistor and the phototransistor.\u003c\/p\u003e \u003cp\u003eAs the light level increases the resistance of the phototransistor decreases, which increases the voltage at the SIG pin. So by reading the voltage at the SIG pin you can determine how much light the phototransistor is being exposed to.\u003c\/p\u003e \u003cp\u003eThe board can easily be connected to a microcontroller and will operate at 3V or 5V.\u003c\/p\u003e \u003ch2\u003eFeatures\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eA phototransistor with easy to use connections\u003c\/li\u003e \u003cli\u003eMeasures the ambient light level\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eContents\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e1 x Ambient Light Sensing Breakout Board\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eConnections\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eVcc: Supply Voltage\u003c\/li\u003e \u003cli\u003eSIG: Analogue Out\u003c\/li\u003e \u003cli\u003eGND: Ground\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eResources\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eAmbient light breakout guide (PDF)\u003c\/li\u003e \u003cli\u003eAmbient light example code (Zip file)\u003c\/li\u003e \u003cli\u003eDimensions: \u003cul\u003e \u003cli\u003eLength: 28mm\u003c\/li\u003e \u003cli\u003eWidth: 18mm\u003c\/li\u003e \u003cli\u003eHeight: 3mm\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003c\/ul\u003e","brand":"Kitronik","offers":[{"title":"Default Title","offer_id":43493249777741,"sku":"alj1787258123350","price":2.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/ambient-light-sensor-breakout-board-discontinued_1.jpg?v=1787258127","url":"https:\/\/www.grandorchard.shop\/products\/ambient-light-sensor-breakout-board-discontinued","provider":"My Store","version":"1.0","type":"link"}
