How to use multiple sensors with Arduino and LCD

20200531· An ultrasonic sensor is an electronic gadget that measures the distance of an object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical sign. Ultrasonic waves travel quicker than the speed of audible sound (for example the sound that humans can hear). Therefore, the performance of this device is really fast.

Best Practices: Occupancy Sensor Placement and Technology

Ultrasonic sensors, unlike PIR sensors, do emit energy into the space and make use of the Doppler effect in order to detect motion. The Doppler effect describes the phenomenon we experience when a moving sound source passes us. For example, when we hear the siren of an approaching police car, the apparent pitch or frequency of the siren changes, increasing as the siren gets closer. This is ...
