Webb20 okt. 2024 · The LDR is used for sensing the ambient light conditions and is used for triggering T1 when the light level crosses a particular set threshold. This threshold is set by the preset VR1. The use of two transistors particularly helps to reduce the hysteresis of the circuit which would have otherwise affected the circuit if only a single transistor would …

WebbAutomatic night light circuit of LM324 Amplifier Circuit Diagram Parts List Circuit Explanation The photoresistor is significant in sensing the incident light intensity and varying its resistance accordingly. Hence, this component activates the nightlight to go on automatically once ambient light dims.
WebbThe transistor provides gain. Basically it's a simple amplifier of the signal produced by the LDR and the pullup resistor. That signal has rather high impedance, so is generally not useful for driving something else directly, like a LED for example. Cheap transistors can easily be found that can be counted on to have a current gain of at least ...
