SENSOR TYPE ULTRASONIC Physical Input High-frequency sound waves Working Mechanism Emits sound waves and measures the time it takes for the echo to return after bouncing off an object Electrical output Voltage pulse proportional to distance

SENSOR TYPE P. I. RPhysical Input Infared (heat) radiationWorking MechanismDetects changes in temperature when a warm body moves pastElectrical output High/low digital voltage signal

SENSOR TYPE L. D. R Physical Input Light intensity (photons) Working Mechanism Changes resistance based on the amount of light striking it Electrical output Variable analog resistance/voltage

SENSOR TYPE PiezoelectricPhysical Input Mechanical stress or pressureWorking MechanismGenerates electric charge when compressed or vibrated.Electrical output Analog AC voltage signal
