One Direction Motion Sensor

Schematic Diagrams      Comments Off on One Direction Motion Sensor

This is a one direction motion sensor circuit. This motion sensor circuit is used to detects an object passing in one direction, ignoring an object that going to opposite way. This circuit uses two sensors to identify the movement only  in one direction. The basic principle of this circuit is… Read more »

UHF Doppler Motion Detector

Schematic Diagrams      Comments Off on UHF Doppler Motion Detector

The UHF motion detector below operates on the Doppler radar principle. A radial signal is created by the oscillator (Q1). Some of this energy is reflected back to the generator by an object in the radiated field. The reflected signal will have a different frequency because of Doppler shift if… Read more »
