The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

An infrared ... LED is placed behind the probe that turns high whenever an obstacle is detected. The E18 sensor operates on 5V and consumes around 5mA to 30mA current without any load. Complete ...

Last and finally, we have the photodiode and the IR emitting LED pair which all together make the total IR Proximity Sensor Module. Types of IR Sensors for Arduino Projects There are several types of ...

Autodesk Eagle .brd and .sch files included with all non-standard libs Sample Arduino code ... (Standard RED 5mm LED with internal resistance is recommended) The board has a normal HIGH and triggered ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ... If everything goes right,you should see the burning eye of the red LED when there is no object in the ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

Sketch for a capacitive proximity / touch sensor with Arduino. This sensor based on a square wave generator rather than charge time measurement as the popular CapSense library. This design results in ...

Thanks to an IR proximity sensor ... animation depending on the number of hand passes over the sensor. The clock itself is based on an Adafruit Feather HUZZAH ESP8266 and a Featherwing display.
