Basic Working Principle: TOF400H ranging sensor is a la-ser ranging ule designed and manufactured based on VL53L1, which provides accurate and repeatable long-distance measurement functions. Thanks to its internal integrated leading SPAD array (single photon avalanche diode) and second-generation FlightSense technology, it can achieve higher ranging distances, more accurate measurement results and higher ambient light immunity. High Precision and Short Measuring Time: TOF400H has a range of up to 4m, and can select high-precision or long-distance test es according to requirements, making it more flexible. The VL53L0X ranging sensor extends the ToF ranging length to two meters, the accuracy is within ±300 and the ranging time is less than 30ms. Features: TFO400H supports serial port e, serial port simulation bus e, and IIC e at the same time, which is well adapted to various application scenarios. Applications: High-speed autofocus, video continuous auto focus, user detection of computers and other equipment, obstacle detection and automatic gesture recognition of white goods (such as faucets, refrigerators, etc.) Colour:red Material:PCB Size:2 x 1 x 0.61cm Package Contents: 1 * Sensor uleOnly the above package content, other products are not included.
