Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...

The DS30 Distance Measurement Sensor is designed to combine simple push button set-up with superior detection performance, all in an industry standard housing. The DS30 line is a proximity style ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

When it comes to measuring distance or movement, would you consider using radar in your design? For many years, the go-to for many applications has been ultrasonics or lasers for non-contact measuring ...
