SMR is a shortcut for Surface Mountable Radar. The current series entails four product variants for motion detection applications. All sensors are radar front ends working in the 24 GHz frequency band. They target low budget segments and offer reliable motion and presence detection of moving objects. Also object distance and speed measurement is possible. Resultant dual-channel operation permits the sensors recognition of motion direction. They detect objects, vehicles or people within a maximum range of 20 m. InnoSenT integrated a low noise amplifier to reduce interferences and improve performance. The products come with low duty-cycle pulse mode enabling reduced power applications (battery or solar). Due to the radar wave propagation characteristics the motion detectors are an optimal solution for indoor and outdoor use and can be inconspicuously placed behind various housing materials. The selected frequency band is approved for worldwide compatibility, without the need of another product version accommodating local regulatory specifications. The SMR series consists of radar front ends without signal processing. This provides customers more customizable development options.
