DIY computer infrared interface
A and B are two common contacts, along with an outline drawing and pin definitions. C refers to the shape of the infrared emission tube, including its pin definition and schematic symbol. CD4069 provides the pin definitions for the inverter...
Infrared Remote Control Tester
Using a battery, a phototransistor, and a visible-light LED, this simple circuit functions as a "go/no go" tester for infrared remote control devices. The illumination of the LED indicates that the phototransistor is being modulated by infrared energy.
This circuit operates...
Selective Preamplifier For Infrared Photodiode Circuit
The circuit utilizes a tuned circuit for frequency selection, designed to operate at approximately 51 kHz. The 2N3565 transistor amplifies the output generated by the tuned circuit.
The described circuit operates on the principle of resonance, where the tuned circuit is...
Doorknob Proximity Alarm for wooden door
Reverse engineered circuit diagram of a popular retail doorknob alarm. It contains a small transmitter and the doorknob acts as an antenna so it will not work on a metal door. When a person comes close to the doorknob this...
Burglar Alarm System Project
This burglar alarm system circuit utilizes an infrared proximity detector that triggers an alarm when the rays falling on its sensor are interrupted. It stands out from other burglar alarm systems due to its simplicity as a DIY project, providing...
Sp6691 Remote Control 100khz Infrared Led Driver
Loop stability analysis typically begins with an open-loop Bode plot of the system being examined, such as the power stage of a buck or flyback converter. This plot allows the designer to extract phase and gain information within the desired...
Invisible Infrared Alarm Circuit
This circuit utilizes invisible infrared light to detect the movement of individuals passing through a doorway. A short beep is produced when the infrared beam is interrupted.
The circuit operates by employing an infrared transmitter and a receiver. The transmitter emits...
Simple Infrared Illuminator
An infrared illuminator emits light in the infrared spectrum and is widely used in night vision cameras to capture images in the dark, particularly in applications such as CCTV cameras.
Infrared illuminators are essential components in various surveillance and imaging systems,...
