XKC-KL800 is a single-point ranging sensor based on the ToF principle. The product has built-in adaptation algorithms for a variety of application environments and targets. With optical and electrical designs, it can achieve stable, accurate, and highly sensitive distance measurement in complex environments. Measurement, when the measured object enters the Fov of the sensor; the sensor determine whether the measured object enters the sensing range set by the sensor's internal system based on the real-time measured distance; if the measured object enters the sensing range, the indicator light behind the sensor light up. When the measured object leaves the sensing area, the indicator light goes out; the sensor output mode is UART serial port, high and low level or NPN. Functional features: 1. Strong anti-interference ability and can be used in the sun 2. Intelligent induction non-contact switch, safe and hygienic 3. Small sensing angle 4. Small size, easy to install 5. Multiple output methods, simple and convenient to use 6. High protection level, with protection circuits such as overcurrent, overvoltage, and anti-reverse connection. 7. In indoor environment, real-time measurement distance up to 8 meters 8. Multi-layer filter cover, more stable induction. Application scope: 1. Intelligent induction sanitary ware, such as faucet induction, automatic flushing of toilets, automatic hand dryers, etc. 2. Home security, such as: anti-theft devices, automatic doorbells, stair and aisle sensors, TV reminders for watching TV at close range, etc. 3. Intelligent detection and intelligent control, such as: automatic doors, advertising light boxes, automatic trash cans, etc. 4. Obstacle identification such as robots and drones. 5. Industrial automation equipment detects distance in real time.
