Emergency Ground Single Loop Detector , Car Vehicle Loop Sensor

Emergency Ground Single Loop Detector , Car Vehicle Loop Sensor IVD-M1H is a single channel inductive loop detectors. The principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles. The changes are picked up and evaluated by a microprocessor. Ease of use thanks to automatic calibration when the operating voltage is applied. MAIN FEATURES : 1) When the DIP switch is on position or changing the presence output
