8-15m LV002 Doppler Radar Microwave Sensor Switch Module

8-15m LV002 Doppler Radar Microwave Sensor Switch Module delivers advanced motion detection capabilities for automated lighting and security installations. This compact microwave sensor board utilizes the Doppler radar principle to detect moving targets within a wide operational range. Therefore, it easily outperforms traditional infrared sensors by penetrating non-metallic materials and operating reliably across diverse environmental conditions. Furthermore, the flexible DC input voltage range ensures seamless compatibility with various power setups. Consequently, engineers and DIY hobbyists frequently choose this module to upgrade standard fixtures into intelligent, energy-saving systems.
