Wireless wheel speed sensor


The wireless wheel speed sensor SENWS1 is a device that can detect wheel speed and temperature in real-time. The device consists of four sensor modules, each of which collects the wheel speed through one channel and temperature through two channels. A total of four channels of the four modules detect the wheel speed in real-time and eight channels detect temperature in real-time, and output the data in real-time through CAN/Ethernet interfaces.

The system wirelessly transmits the collected wheel speed and temperature to the receiving end, which outputs the data from the CAN/Ethernet interface, making it very convenient to monitor the wheel speed and temperature.

Application scope

Wireless wheel speed steering wheel, a device used for real-time detection of wheel speed and temperature.
