It works over an input voltage range of 3.0 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis compact sensor is a great way to quickly detect the presence of nearby objects. As long as the sensor is enabled, it takes continuous distance measurements and uses a single digital output to indicate if it detects an object within its detection range. The output is driven low when the sensor detects an object; otherwise, the output is high.\u003c\/span\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePlease note that this sensor will only tell you \u003cem\u003eif\u003c\/em\u003e there is an object within the detection range along its line of sight, not how far away it is. As shown in the diagram in the product images, there is hysteresis at the maximum range threshold to help ensure a clean transition as objects cross the threshold. The sensor can detect objects to within about 5 mm of the sensor face.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eUnlike simpler optical sensors that use the intensity of reflected light to detect objects, this sensor uses a short-range lidar module to precisely measure how long it takes for emitted pulses of infrared, eye-safe laser light to reach the nearest object and be reflected back. This allows the sensor performance to be largely independent of object reflectivity and ambient lighting conditions (though the range can be reduced for extremely low-reflectance objects).\u003c\/p\u003e\n\u003cp\u003eSome example applications include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ebreak-beam sensor or photogate alternative\u003c\/li\u003e\n\u003cli\u003enon-contact bumper or obstacle detector for a robot\u003c\/li\u003e\n\u003cli\u003enon-contact interface element for activating a device or process\u003c\/li\u003e\n\u003cli\u003ea counter or timer of objects as they pass by\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eImportant note:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThis product might ship with a protective liner covering the sensor IC. \u003cins\u003eThe liner must be removed\u003c\/ins\u003e\u003cspan\u003e for proper sensing performance.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOperating voltage: 3.0 V to 5.5 V\u003c\/li\u003e\n\u003cli\u003eCurrent consumption: 30 mA (typical) when enabled, 0.4 mA when disabled\u003c\/li\u003e\n\u003cli\u003eMaximum range: \u003cstrong\u003e10 cm (4″)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMinimum range: \u003cstrong\u003e\u0026lt; 5 mm\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMinimum update rate: \u003cstrong\u003e115 Hz (8.7 ms period)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eField of view (FOV): 15° typical; can vary with object reflectance and ambient conditions\u003c\/li\u003e\n\u003cli\u003eOutput type: digital signal (low when detecting an object, high otherwise)\u003c\/li\u003e\n\u003cli\u003eDimensions: 0.85″ × 0.35″ × 0.122″ (21.6 × 8.9 × 3.1 mm); see the\u003cspan\u003e \u003c\/span\u003edimension diagram\u003cspan\u003e \u003c\/span\u003e(191k pdf) for more information\u003c\/li\u003e\n\u003cli\u003eWeight: 0.014 oz (0.4 g)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUsing the sensor\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eThree connections are necessary to use this module: VIN, GND, and OUT.

The OUT pin drives low (0 V) when an object is being detected and it drives high (to the VIN level) when an object is not being detected. It is weakly pulled high when the sensor is disabled or waiting for its first reading to complete after power-up. A red LED on the backside of the board also lights whenever an object is detected.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe board has an optional ENABLE pin that can be driven low to put it into a low-power state that consumes approximately 0.4 mA.

The sensors on these newer units are much thinner than the Sharp modules, so the zero-range point is approximately 7mm closer to the PCB, and the beam angle of the newer units is wider.\u003c\/p\u003e","brand":"Pololu","offers":[{"title":"Default Title","offer_id":43643618787389,"sku":"orm1789691276225","price":20.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/9716\/8957\/files\/pololu-digital-distance-sensor-10cm_1.jpg?v=1789691282","url":"https:\/\/laser-engraved-clasp.shop\/products\/pololu-digital-distance-sensor-10cm","provider":"My Store","version":"1.0","type":"link"}
