Sell Speed detector board VL8

1. INTRODUCTION

This is a module for configured sublac. it is a 4 channel ****6 *6bit microprocessor based detector designed specifically for AVI applications.

The primary function of the detector is to detect vehicle speed, distance each vehicle, vehicle length by means of an inductance change

caused by the vehicle passing over a wire loop buried under the road surface.

The various data values are setted by setting port with laptop easily.

This module uses *6bit frequency counter for better accuracy. furtuermore it can support all kind of communication type, such as
