Here is a simple optoreflective sensor circuit based on TCRT5000 module. It is ideal for projects like robotics, position sensing, proximity sensing, detection of reflective materials and many more.

Circuit diagram . Tilt Sensor . This is a Mercury switch based tilt sensor module that gives high at its output pin when tilted. It requires a 5V of DC input. It’s a three-terminal device consist of ...

The reflector is based on a frequency selective surface (FSS) consisting of slot-excited substrate integrated waveguide (SIW) resonators. Resonator modes are analyzed and an equivalent circuit diagram ...
