The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

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 ...

Being able to easily see that the IR temperature sensor costs $26 at DigiKey is unbelievably helpful to readers. ... Continue reading “Modular Arduino Based Infrared Thermometer ...

The automatic AC temperature controller is built around an Arduino mega development board. A DHT11 sensor is used to detect the ambient temperature and humidity. A TSOP1738 IR sensor is used to decode ...
