Reflected light intensity detecting circuit CD4052B CD4011B
The circuit for detecting the intensity of reflected light includes infrared light-emitting diodes, photodiodes, CMOS analog switches, operational amplifiers, and other components. When the circuit operates, the infrared light-emitting diode (LED) initially remains off, allowing the photodiode to receive external...
The passive human body infrared sensor circuit
Passive human body infrared sensor circuits are generally similar in design, although some may have fewer stages. The circuit illustrated is sourced from the NICERA manufacturer and is considered a classic example. The front-end stage consists of a low-frequency signal...
Remote controlled LED
The remote control transmits encoded signals. Each time a key is pressed, the relevant code is transmitted, usually repeating it many times to ensure reception. This encoded signals travels over a radio or infrared-light beam, to eventually get captured by...
Infrared Switch Circuit
A simple infrared-controlled switch can be operated using a TV remote control. The load can be any AC-powered device connected to the relay. The load activates for three minutes before turning off and can be used to switch on a...
Remote Control Your Computer
Envision a scenario where one is comfortably reading a favorite novel while enjoying music on a computer. Suddenly, the desire arises to skip the current song or pause the MP3 player. An infrared software solution is available that decodes electrical...
Infrared Wireless Headphones circuit
The transmission circuit for inductive wireless headsets must be securely mounted on a wall or ceiling, limiting its outdoor usability, which is a significant disadvantage of inductive wireless headphones. In contrast, infrared wireless headsets utilize a compact infrared transmitter circuit...
Simple Ir Transmitter
The flash rate of the IR diode is determined by the value of CI, a 220-µF capacitor that sets the oscillation rate at 1 Hz per second. Reducing CI will increase the frequency of the circuit, while larger values will...
infrared detector circuit
This is a straightforward infrared detector circuit designed to detect infrared light. The circuit comprises only three components: an RS-276-145 photo transistor, a 330-ohm resistor, and a general-purpose LED (Light Emitting Diode). When the photo transistor receives infrared light on...
Glue stck torch
This project, developed around 2005, involves constructing a torch using a glue stick, which conveniently accommodates an AA battery within its plastic casing. To create a functional battery holder, contacts for both the positive and negative connections are necessary. The...
