This circuit does not detect object movement but can act as an proximity sensor! Presence, Proximity Sensor Circuit Schematic proximity sensor circuit schematic. The sensitivity of the proximity ...

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 ...

Arduino Code for Interfacing MQ-5 Gas Sensor Module. The Arduino MQ-5 gas sensor module's coding is straightforward. We're simply reading the Sensor's analog data and turning the LED and Buzzer ON or ...

[Dustin Andrews] built this add-on board which works as a proximity sensor. He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger. This lets him alert ...

ACAT_Arduino_Proximity_Sensor.ino – Main Arduino "sketch file". Loaded into Arduino Software IDE and connects the proximity sensor logic to the AcatActuator logic VCNL4010 – VCNL4010 proximity sensor ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Capacitive proximity sensor uses electric fields to detect contactless objects like human body. Owing to its simplicity and low cost, it is an attractive choice for the application of human-computer ...
