The sensitivity of the proximity sensor circuit can be adjusted with P1 for the desired “distance”. One of its obvious uses is to open a door automatically. For this the sensor must be placed on the ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

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 ...

Abstract: An electrical injury protection system is being developed to protect electrical workers from electrical injury and electrocution by human proximity and electrical contact sensing. Proximity ...

Both color and proximity sensors have many medical device applications. But because of the negative effects on color sensing caused by infrared (IR) light, which is required for proximity sensing, the ...
