Digital Laser Adjustable Proximity Sensor for Arduino / Raspberry Pi (1-400cm, IP67)

The Digital Laser Proximity Sensor is designed for versatile and demanding environments. Leveraging laser diffuse reflection technology, it provides an adjustable detection range of 1-400cm, configurable via an onboard button without coding. With ±4% accuracy and a 35° detection angle, it surpasses traditional IR sensors in precision and range. Its IP67 waterproof and dustproof rating ensures reliable performance in harsh outdoor or industrial conditions. The digital output seamlessly integrates with platforms like Arduino and Raspberry Pi, making it ideal for applications such as robotic obstacle avoidance, smart home security, and industrial automation. Additionally, the sensor’s digital signal output is compatible with Arduino IO expansion boards, enabling use in outdoor long-distance detection applications like smart parking, AGV navigation, and automated farming. Certified with CE and RoHS, ensuring compliance with international safety and environmental standards.

Adjustable Detection Range (1-400cm)

The Digital Laser Proximity Sensor’s 1-400cm adjustable range far exceeds the capabilities of traditional IR sensors (typically limited to 50cm). This flexibility allows it to adapt to diverse scenarios, from short-range object detection to long-distance monitoring. The onboard button simplifies configuration, enabling users to set the desired detection range without complex programming. This feature is particularly valuable for applications like AGV navigation in warehouses, where varying shelf heights require dynamic range adjustments.

IP67 Waterproof & Dustproof Design

Built to withstand harsh environments, the Digital Laser Proximity Sensor’s IP67 rating ensures reliable operation in rain, snow, dust, and high humidity. Its PC-V0 fireproof housing and sealed construction provide durability and safety, making it suitable for outdoor applications such as smart parking systems or agricultural machinery. Unlike traditional sensors that require additional protective enclosures, this sensor can be directly installed in challenging conditions, reducing maintenance costs and complexity.

High Precision & Digital Output

With ±4% accuracy and a 35° detection angle, the Digital Laser Proximity Sensor delivers precise and consistent results. Its digital output (high/low level) integrates seamlessly with platforms like Arduino and Raspberry Pi, enabling easy integration into IoT systems, robotics, and smart home devices. The active detection mode ensures rapid response to objects or individuals entering the sensing range, making it ideal for security systems or automated control applications.
