Third Reality's New PIR Based Motion Sensor Now AvailableThird Reality has introduced the Motion Sensor R1, a device designed to improve motion detection in smart homes. This is a PIR based motion sensor, so uses passive infrared to detect motion.
Most of us would probably expect to see a PIR sensor, but this light is motion sensing with microwaves. We have seen such units tested in the past, which links to a video [hclxing] also references.
this DIY motion trigger for a DSLR is a quick and easy build, and probably loads more fun. The BOM on [Jeremy S Cook]’s build is extremely short – just a PIR sensor and an optoisolator ...
