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
