Infrared proximity sensor serial Si1143 of Silicon Labs Company

The electronic device detects proximity, measuring the user's distance quickly. Currently, most proximity sensors available on the market have a relatively short detection range of approximately 1 to 10 cm. The use of infrared LEDs in multipulse mode for extended...

remote circuit

The cause may be dry solder joints, defective LEDs, or a flat battery (possibly due to a stuck key). The human eye cannot perceive infrared light, while a standard phototransistor such as the BP103 operates effectively in the infrared spectrum....

USB Ultra IR-Receiver v2.0 to PC remote control and power ON - OFF

This Atmel integrated circuit operates at a clock frequency of 12 MHz, facilitating communication between an infrared receiver and a personal computer. This setup enables the processing of signals by infrared receiver software, such as Girder. When a valid RC5...

Homemade infrared automatic door controller circuit

Automatic door control systems typically have a high market price for finished products. The proposed method is suitable for home use, utilizing easily accessible components. This design is ideal for those interested in creating their own automatic door system. The...

Infrared circuits for remote control

Infrared remote controls are using a 32-56 kHz modulated square wave for communication. These circuits are used to transmit a 1-4 kHz digital signal (OOK modulation) through infra light (this is the maximum attainable speed, 1000-4000 bits per sec). The...

Infrared Alarm

This circuit consists of two parts, the first part will transmit a signal, and the second part will detect that signal and trigger a relay. To adjust the circuit, hold down S1 while pointing LED1 at the receiver. Adjust R6...

Basic IR Detector/Emitter

This is a very basic infrared detector/emitter circuit. One major downside of this circuit, is that ambient infrared light will interfere with its detecting obstacles. The described circuit functions as a basic infrared (IR) detector and emitter system, commonly utilized in...
