Unique device operates in the GHz range and detects human movement though walls, windows, etc. This 1.46″ x 0.92″ x 0.47″ thick. Assembly uses radar to detect humans up to 25ft. The sensor operates on 5VDC and has an output that can light a LED or activate a relay. Note: this device is very sensitive and is subject to false triggering from RF sources such as Wi-Fi, EMF, etc. and power supplies. Fascinating to use and experiment with. Hookup info shown in PDF. Board assembly with cable only. (LED, resistor, battery holder and batteries not included). New!

Note: We assembled a demonstration with additional parts sold separately: Battery Holder, Giant LED, 47 Ohm Resistor.
