It requires less power to operate, has a longer range (up to 6m) and it performs its own internal timing of the return echo. The SRF08 is also fitted with an LDR to measure light levels. \u003c\/p\u003e \u003cp\u003eCommunication with the SRF08 is via the I2C bus that is available on many popular microcontroller's. \u003c\/p\u003e \u003cbr\u003e \u003c\/section\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003csection class=\"info_SPECIFICATION\"\u003e \u003ch5\u003eSpecification\u003c\/h5\u003e \u003cul\u003e \u003cli\u003eVoltage - 5v only required\u003c\/li\u003e \u003cli\u003eCurrent - 15mA Typical. 3mA Standby.\u003c\/li\u003e \u003cli\u003eFrequency - 40KHz\u003c\/li\u003e \u003cli\u003eRange - 3cm -6m (1.2-2.4in).\u003c\/li\u003e \u003cli\u003eMax Analogue Gain - Variable 94 to 1025 in 32 steps.\u003c\/li\u003e \u003cli\u003eConnection - Standard I2C Bus.\u003c\/li\u003e \u003cli\u003eLight Sensor - Front Facing light sensor.\u003c\/li\u003e \u003cli\u003eTiming - Fully timed echo, freeing host controller of task.\u003c\/li\u003e \u003cli\u003eEcho - Multiple echo - keeps looking after first echo.\u003c\/li\u003e \u003cli\u003eUnits - Range reported in uS, mm or inches.\u003c\/li\u003e \u003cli\u003eSmall Size - 43mm x 20mm x 17mm (1.7x0.8x0.7 in) height. \u003c\/li\u003e \u003c\/ul\u003e \u003cbr\u003e \u003c\/section\u003e\u003cp\u003e \u003c\/p\u003e\u003ch5\u003eDocuments\u003c\/h5\u003e \u003cp\u003e \u003c\/p\u003e\u003cul\u003e\n\t\u003cli\u003eManual\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Devantech","offers":[{"title":"Default Title","offer_id":48623752052954,"sku":"iop1789677443729","price":46.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/srf08-ultrasonic-sensor-discontinued_1.jpg?v=1789677448","url":"https:\/\/memoryfoamwear.shop\/products\/srf08-ultrasonic-sensor-discontinued","provider":"My Store","version":"1.0","type":"link"}
