This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

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. A5 is used as a “floating input”, but unfortunately it is very ...

The IR Detector proximity sensor has launched via Kickstarter and is now available to back from just $5 with worldwide delivery expected to take place during February 2019.
