  • Dark/Light Detector using 555 Timer & LDR -

    2020-5-13 · Here we have explained a Dark/Light Detector using 555 Timer & LDR (Light Dependent Resistor) which senses the light in surroundings and if it does not find the light, it triggers the IC and glows an LED attached with the circuit. In place of LED we can also use a buzzer or speaker to use it as dark detector alarm.

    2020-5-19 · Working Principle of Darkness Detector. First, we will start with the 555 timers. It is configured in astable mode. When there is light falling into the LDR, its resistance becomes very low. In this condition, the voltage divider will produce almost 0V from its output formed by 1 MΩ resistor. In this situation, the 555 timer IC will be reset.

    2015-8-5 · It is much easier, at least for me, than using the 555 as a schmitt trigger, where the hysteresis is so large (1/3 Vcc), unless a control voltage is applied to pin 5. For instance, if 2V is applied to pin 5, the hysteresis will only need to go from 1v to 2V (which is actually 1/2 Vcontrol to Vcontrol). Still, this complicates the setup.
