Microwave Radar vs PIR Infrared Sensor for Solar Street Lights: Which One Fits Your Road Project?
Jun 23, 2026
Introduction
Nowadays, almost all integrated solar street lights are equipped with motion sensors to realize intelligent dimming, greatly extending battery standby time and reducing energy consumption. Two mainstream sensing solutions dominate the market: PIR infrared sensor and microwave radar sensor.Many contractors and municipal buyers only judge products by upfront cost and choose PIR lights. After installation, they face frequent sensing failure, dim road lighting and high annual maintenance costs, especially in coastal foggy towns, frigid mountain areas and tropical regions with year-round morning mist.Our XCPB all-in-one solar street light adopts upgraded microwave radar sensor as standard factory configuration. This guide fully compares the working principle, pros &...
