LinkSprite infrared roadblock sensor uses an integrated infrared transceiver.  74LS00 is used to construct a resonator. Adjust the potentiometer can adjust the frequency of the infrared light to be the center of receiver, i.e. 38kHz. Now the...

Flame sensor is only sensitive to the light in the frequency band of infrared and ultrviolet. This breakout board has 3 pins: sensor output signal, power, and ground. The sensor output signal is an analog signal. In an indoor enviroment, the...

Path tracking sensor uses a reflective infrared sensor (tcrt500). The infrared light is emitted and reflected back to the receiver, it's then inverted by 74LS14 and output to the output pin and the LED. The output signal is a digital signal.  There...

The infrared remote control kit for Arduino consists of the receiver module, remote control and the jumper wire. The receiver module uses HS0038, the integrated receving element, which includes the sensing, amplify, recitify, and outputs the TTL signal...

These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is...
