SKU: DF-SEN0149

Ultrasonic sensors emit ultrasonic pulses, and by measuring the time of ultrasonic pulse reaches the object and back to the transducer, the distance of sensor from the target object is calculated. They are widely used in detecting displacement, thickness, distance, water level, material level and...

SKU: DF-SEN0306

A K-band 24GHz millimetre-wave ranging radar sensor with isolated transmitter and receiver antennas. Using FMCW modulation, it measures distance to object surfaces by transmitting and receiving microwaves, with all signal processing integrated on-board. Distance data is output directly via an asy...
