Product Details
This advanced digital laser proximity sensor, an upgraded version of the Digital IR Proximity Sensor (SKU: SEN0381), provides a longer sensing distance and an indicator to show real - time sensor status. Press and hold the on - board button for 3 seconds, and the indicator will flash. You can then adjust the detection distance from 1 to 400cm according to your needs. The sensor can automatically detect and save the distance to the obstacle ahead. With digital signal output, it works great with the Arduino IO expansion board. Ideal for smart homes, house security, intelligent detection and control, and robot obstacle avoidance. It uses the principle of laser diffuse reflection. When a person or object enters the sensing range, it outputs a signal; when they leave, it stops. This enables intelligent control. It's compatible with DFRduino UNO R3 and IO Expansion Shield. Key features include a wide range of applications, an on - board button for distance adjustment, and laser sensing up to 4m. Specifications: Power Supply: DC 5 - 24V, Load Current: 300mA, Operating Current: 15mA, Detection Distance: 1 - 400cm adjustable, Detection Accuracy: ±4%, Wavelength: 940nm laser emitter, Output Mode: high/low level, Detection Angle: 35° (transmit), 25° (receive), Short Circuit Protection: disable output over 1A, Detection Mode: active mode, Operating Ambient Temperature: - 20 - 70°C, Storage Temperature: - 20° - 85°C, Waterproof Performance: IP67, Material: filter - PC optical material, housing - PC - V0 fireproof material. Comes with a product wiki and one Digital Laser Proximity Sensor (1 - 400cm).
Using this digital laser proximity sensor is easy. First, connect it to a power supply within the 5 - 24V DC range. It's compatible with DFRduino UNO R3 and the IO Expansion Shield, so you can use it with those easily. To adjust the detection distance, press and hold the on - board button for 3 seconds. The indicator will start flashing, and you can set the distance from 1 to 400cm. Remember, the detection accuracy is about ±4%. When using it, make sure the sensor is placed in an area where it can detect obstacles effectively. The detection angle is 35° for transmitting and 25° for receiving. In terms of maintenance, keep it away from extreme temperatures. The operating temperature range is - 20 to 70°C, and for storage, it's - 20° to 85°C. Since it has an IP67 waterproof rating, it can handle some water exposure, but don't submerge it for long periods. Also, the sensor has short - circuit protection. If the current exceeds 1A, the output will be disabled. Check the product wiki for more detailed information and troubleshooting tips.
