With strong reflectance, the output voltage tends towards GND; with weak reflectance, it tends towards Vcc. The resistor wired in series with the infrared LED sets the operating current to a safe ...

The circuit is based around this Sputnik-looking standalone IR temperature sensor which, as [MakeFunStuff] aptly describes, is “a single-pixel infrared camera that picks up everything in a 90 ...

When an object comes within the sensor's range, the amount of reflected light changes, causing the sensor’s output to switch state. Arduino Processing: The Arduino reads the output from the IR sensor.

This project uses an IR sensor with an Arduino to detect the presence of an obstacle. The IR sensor emits infrared light and detects the reflected light from an object. When an object is detected, the ...

Components Required For building a basic robot like this one, the components are quite flexible, and you can always scale up or down depending on your needs. Below are the components, that I used in ...

LEDs on the Arduino can be programmed to indicate if the sensor is/isn’t immersed by the liquid (and thus determine if liquid level is too high/low). The two companies say that the hardware provides ...
