Compact Fast Response Waterproof IR Proximity Sensor for Arduino (100µs, 10-80mm)

The Infrared (IR) Proximity Sensor is designed for close-range object sensing in space-limited and moisture-prone environments. Utilizing diffuse reflection principles, the sensor emits infrared light and measures the reflected signal to determine object presence within a 10–80mm range. Key parameters include a 100µs response time, 5V operating voltage, and a sealed waterproof housing. It is tailored for applications requiring rapid, reliable proximity detection in challenging conditions, such as smart sanitary devices, industrial automation, and IoT systems.

Ultra-Fast 100µs Response Time

The Infrared (IR) Proximity Sensor achieves a 100-microsecond detection speed, 10x faster than conventional IR sensors (>1ms). This near-instantaneous response eliminates lag in time-critical applications, ensuring precise synchronization in automated processes. For example, in robotic grippers, the sensor instantly detects object presence, enabling real-time adjustments to grip force or positioning.

Compact Waterproof Design with Integrated Mounting

Featuring a miniaturized structure and pre-drilled mounting holes, the Infrared (IR) Proximity Sensor seamlessly integrates into confined spaces while maintaining IP67-equivalent waterproof performance (implied by sealed housing and humidity resistance). The absence of mechanical components enhances durability, with a 50,000-hour lifespan even in high-splash environments like public restrooms or outdoor installations.

External Light Immunity and Stability

Advanced optical filtering and signal processing algorithms minimize interference from ambient light sources (e.g., sunlight or indoor lighting). This ensures consistent accuracy in variable lighting conditions, critical for applications like automatic hand dryers in brightly lit areas or assembly line QA checks under factory lighting.
