Light controlled ultra-low frequency oscillation circuit diagram
Source: InternetPublisher:拿铁三分糖 Keywords: Optical control oscillator circuit physics/optics Updated: 2020/04/09
Shown is a light-controlled ultra-low frequency oscillation circuit, which is mainly composed of a power supply circuit, an ultra-low frequency oscillation circuit and an electronic switch circuit.
The power supply circuit is mainly composed of capacitor cl, resistor V, Zener diode vs, rectifier diode VD and filter capacitor C/. The mains AC 220 V voltage reduces the voltage of capacitor C1, diode vs stabilizer, diode VD rectifier and After filtering by capacitor C2, it outputs DC +5 V voltage to power other components in the circuit.
The ultra-low frequency oscillation circuit is mainly composed of photoresistor RG, adjustable resistor RP, transistor vr2 and peripheral related components. Tuning the resistance value of RP can change the frequency of the oscillator and the light control sensitivity.
