1、Descriptiion
TOF400F ranging sensor is a laser ranging module 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.
TFO400F supports serial port mode, serial port simulation Modbus mode, and IIC mode at the same
time, which is well adapted to various application scenarios.
It is equipped with a host computer for easy debugging.
TOF400F has a range of up to 4m, and can select high-precision or long-distance test modes according
to requirements, making it more flexible. The ranges are as follows:

Features
・ The 940nm laser meets the Class 1 operating
conditions specified in the third edition of IEC 60825-
1:2014
・Sensor size (18X17X6.5mm)
・ The maximum measurement distance indoors can
reach 2 meters, and the accuracy is within 5%
・ The measurement range has nothing to do with the
reflectivity of the target object
・ Can work in high infrared light environment
・ High optical crosstalk compensation
・ Measurement time is less than 30ms
・ Lead-free
・ No need for additional optics
・ Single power supply
・ Standard TTL level serial port I2C
・ High optical crosstalk compensation

Applications
・ High-speed autofocus
・ Video continuous auto focus
・ User detection of computers and other
equipment
・ Obstacle detection
・ Automatic gesture recognition of white
goods (such as faucets, refrigerators, etc.)
