Weather stations are a popular project for experimenting with various environmental sensors, and for wind speed and direction the choice is usually a simple cup anemometer and wind vane. For [Jianj… ...

Most ultrasonic sensors have an auto-window feature: If a target is caught twice at the same distance, the sensor automatically creates a near and far limit around the target (typically ±5 or 10 mm).

The CH-201 employs a tiny ultrasonic transducer chip that sends a pulse of ultrasound and then listens for echoes returning from targets in the sensor’s field of view. By calculating the distance ...

Proximity sensors that use ultrasonic sound waves calculate distance to an object using the time it takes to receive the echo from an ultrasonic burst. But, similar bursts from other sensors in ...
