Infrared burglar alarm circuit
An infrared reflective burglar alarm utilizes infrared detection through reflective components, with a maximum detection range of up to 12 meters to trigger an alarm. When an intrusion is detected, a realistic barking sound is emitted to alert the owner...
Simple TV Remote Control Jammer
This circuit disrupts the infrared receiver in a television by generating a continuous signal that interferes with the remote control signals, preventing the TV from recognizing channel changes or other commands. This allows for uninterrupted viewing of a chosen program...
Inexpensive Remote Watering System
This remotely controlled watering system is cost-effective and easily expandable. It operates in conjunction with a conventional watering timer, enabling remote switching between nine zones. The prototype is designed for use with a bore system, where a deep-well pump must...
Remote-Controlled Switcher
This single-cable system transmits composite video (NTSC, PAL, or SECAM), power, and channel selection signals. The interface end of the circuit delivers 10 V down the cable, pulses the supply voltage to transmit channel-change commands, and buffers the received video...
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...
Infrared Remote Control for operates on 115 volts AC
Infrared remote control operates on 115 volts AC. This circuit enables the activation of any equipment that functions on 115 volts AC. The receiver circuit is based on the Radio Shack infrared system.
The infrared remote control circuit designed for operation...
Wireless Ir Headphone Transmitter Circuit
The transmitter for the wireless headphones is constructed using a CD4046 CMOS phase-locked loop, which is paired with a driver transistor and a set of infrared LEDs. While the CD4046 contains two phase comparators, a voltage-controlled oscillator (VCO), a source...
SC41343 general infrared ultrasonic or RF remote control launch coding circuit
The SC41343 is designed as a type of infrared, ultrasonic, or RF remote control launch coding circuit. The internal circuit comprises a sequence generator, control logic circuit, 4-bit shift register, data extraction circuit, and latch circuit. Features include the use...
TX05C-R infrared surveillance alarm circuit
The TX05C-R infrared surveillance alarm circuit is designed for monitoring walls, windows, doors, and various restricted areas. When an intrusion occurs, the alarm activates to enhance security. The circuit comprises a transmitter module, a receiver module, a time-base circuit, a...
