The full name of ToF is Time of Flight (Time of Flight) technology. This technology sends continuous light pulses to the target, then uses a sensor to receive the light returned from the target, and detect the flight (round trip) time of the light pulse to obtain the target distance. information. In recent years, ToF ranging technology has been widely used in consumer electronics, automobiles, industrial vision inspection and many other fields. While further extending the detection range, the emergence of ToF technology greatly simplifies the design complexity of the ranging module , Which caters to the current trend of miniaturization of mainstream products.

The TMF8801 equipped in the solution is a time-of-flight sensor product that combines ultra-small size and high-precision measurement. Its volume is only 2.2mm x 3.6mm x 1.0mm, which is nearly 30% smaller than the same type of sensor product on the market. . The product integrates a VCSEL infrared transmitter, multiple SPAD (Single Photon Avalanche Photodiode) photodetectors, a time-to-digital converter, and an on-chip microcontroller that implements histogram processing, providing excellent ToF performance and ultra-low power consumption Characteristics.

With the performance of the LPC804 and TMF8801 products, this solution has the advantages of large range, long distance, and high accuracy. It can be used in anti-collision of sweeping robots, intelligent dimming projector, intelligent brightness adjustment, intelligent lamp automatic dimming, and intelligent water cup measurement. Application areas such as water volume shine brightly.
