Availability: In stock SKU: IWP-00573 Categories: Sensors , COVID-19 Special , IoT Components , Raspberry Pi Sensor , Arduino Sensor Tag: motion sensor It does this by bouncing a microwave signal off a desired target and analyzing how the object’s motion has altered the frequency of the returned signal. More commonly, though, it transmits and receives pulses, measuring the range or distance to a target based on the delay time of the pulses and the velocity of the target based on the Doppler frequency shift of the received signals. For most practical applications that signal needs to be amplified a lot. always on. One approach is to use the “find a need and fill it” method of product development.
