The transmitter section consists of a 555 timer IC functioning in astable mode. It is wired as shown in the figure. The output from astable is fed to an infrared LED via resistor R4, which limits i...

In that circuit I used the photodiode Snap Circuits block (Infrared Receiver U24) as the infrared detector. Even though a photodiode was useful for building a simple IR detector, another electronic...

It use a pair of circuit diagrams that are IR transmitter and IR reveiver. Using this low-cost project one can reproduce audio from TV or other electronic devices without disturbing others. It does...

What is PIR ?Passive Infrared Sensor Circuit Diagram. Detectors or pyroelectric sensors, passive infrared or PIR sensor, are made of a crystalline material that generates an electric charge on the ...

This infrared remote control can control working of 2 channel or can use to control two Electric appliance, each one on-off freely and a maximum of 300 watts on Control distance is 50 feet. How doe...
