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 ...

In the microcontroller era today, Arduino ... is below a threshold value. Here an LDR (Light Dependent Resistor) is used to measure the light level. The alarm system is triggered when a “Logic High (H ...

To replicate Krejci’s design, you need an Arduino UNO Rev3 board, an AMG8833 infrared sensor module ... exceeds or falls short of your predefined threshold. Capable of detecting human presence ...

We’ve featured loads of IR Arduino projects and they are all exciting ... Maybe he will add a temperature sensor someday so it doesn’t have to run on strictly time. A more complicated problem ...

This specific sensor was chosen because others have successfully interfaced it with the Arduino. Not having to reinvent the wheel is good thing! For the build, [Brian] decided to hook up the IR ...
