This device is a receiver circuit for a Digital Remote Thermometer. The thermometer operates by converting the sensor’s output voltage, which is calibrated and proportional to the measured temperature ...

The Infrared Remote Control Switch is a simple electronic circuit that uses an infrared (IR) receiver to detect signals from a standard TV remote and control an electrical load, such as a lamp or ...

The transmitter and receiver circuits of the infrared alarm system shown here have been designed for a range of several meters, almost independent of ambient light conditions. Only in the rare case of ...

The architecture of a low-complexity ultra wideband (UWB) impulse radio (IR) transmitter and receiver circuit, aimed for low-cost applications is presented. To project a simple and commercially ...

But this time the receiving side was swapped out, as [GreatScott] built a basic circuit around a TA7642 AM amplifier/demodulator IC, with only six passive components and a hand-wound coil.
