Time-of-flight ultrasonic distance sensor TOF10120 range sensor provides accurate and repeatable long range distance measurement for high-speed autofocus (AF). The innovative time-of-flight technology enables performance of object reflection. TOF10120's time-of-flight sensing technology is realized by 's SPAD (Single Photon Diodes) with low-cost standard CMOS process. It allows accurate in result, higher immunity to ambient light and better ruggedness to cover-glass optical crosstalk through special optical package design. 940nm as class 1 under operating condition Long range absolute pallet measurement up to 1.8m Within 5 % accuracy inside Reported range is of target reflection Operates in high infrared ambient light levels Advanced optical -talk compensation High speed range MAX 30 msec Single power supply Txd interface for device control and data transfer High-speed AF Continuous AF for video Laptops / tablets Robotics (obstacle detection) Range range 100 ~ 1800mm colour:Photo Color Material:plastic Package Contents: 4 * Range Sensor Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
