I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I. ... to ~38kHz signal yielded by D9 of the ...

Upload the Arduino IR sensor code provided below; Adjust the sensitivity potentiometer for the desired Arduino infrared sensor distance; Test with the serial monitor for the IR sensor with Arduino Uno ...

The Arduino Uno Infrared Emission Sensor Module emits infrared (IR) light and detects its reflection to measure distances or detect objects. It typically includes an IR LED and a photodiode, enabling ...

The Arduino Uno IR Flame Sensor detects the presence of flames or fire by sensing infrared radiation emitted by them. It typically includes an IR receiver that detects the specific wavelength of ...

IR sensor’s output pin is connected to Arduino, so Arduino will read it and activate the Relay module by making pin 7 high. As soon as relay is activated, it will turn on the DC motor. When there is ...

So this inspired us to use GSM module for this project since the telecom network is widely spread within rural & urban area of the India. This system is used to monitor physical parameter like heart ...

System consists of an IR base heart beat sensor, Arduino Uno & GSM module. This device will be able to measure heart beat from an infant to elder person. The low cost of the device will help to ...
