Infrared automatic faucet circuit diagram
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.
