Unidirectional Microwave Sensor for Automatic Door 24.125GHz Single Direction Microwave Radar Motion Detector

Brief Introduction

This microwave radar sensor, with the features of high sensitivity, fast and accurate response, can be used for various automatic doors. The sensor only detects approaching movement but ignores the departure (one-way detection only). It can effectively prevent both interior and exterior probes from unnecessary secondary sensing, and avoid the misjudgment because of door vibration (especially on industrial fast door shutting down).
