Infrared automatic faucet circuit diagram
Description: The circuit consists of the following components: (1) An infrared emitter which utilizes a multi-harmonic oscillator based on a 555 timer circuit. The oscillation frequency is determined by the values of RP1, R1, and C1, resulting in a frequency of 38 kHz. (2) An infrared receiver circuit that includes an infrared receiver tube (VD2) and a CX20106 integrated circuit. (3) A water valve control circuit composed of controlled gates F1 and F2, a drive tube (VT1), and relay (K1). (4) A lamp control circuit which includes control gates F3 and F4, a drive tube (VT2), and relay (K2).
The circuit operates as a comprehensive control system for various applications. The infrared emitter generates a modulated infrared signal at a frequency of 38 kHz, which is optimal for many infrared communication applications, ensuring minimal interference from ambient light sources. The 555 timer is configured in astable mode, with the oscillation frequency being adjustable through the resistors and capacitor connected to it.
The infrared receiver circuit is designed to detect the emitted signal. The infrared receiver tube (VD2) captures the infrared light, while the CX20106 serves as a demodulator, processing the received signal to trigger subsequent actions in the circuit.
The water valve control circuit allows for automation of water flow using controlled gates (F1 and F2) to manage the opening and closing of the valve. The drive tube (VT1) amplifies the control signal, while relay (K1) acts as a switch to physically control the water valve.
Similarly, the lamp control circuit operates in a parallel fashion, where control gates (F3 and F4) manage the operation of a lamp. The drive tube (VT2) amplifies the control signal for the relay (K2), enabling or disabling the lamp based on the received infrared signal.
