The negative and positive pulses are given to the trigger and threshold pins of 555 through the light activated phototransistors T1 and T2. Automatic On Off Light. There are two important components in this circuit first is PIR Sensor Passive Infrared Sensor and second is Relay.
Dusk To Dawn Light Bulb. The optocoupler is used to have complete galvanic isolation between the control circuit and the power circuit. You do not need to dim the lights by yourself.
To understand the working operation of the light sensor circuit we must know a brief about the components used in designing the light sensor circuit. 220v AC LED Chaser Circuit. So we are using relay as switch to control high power devices.
Automatically control lighting in offices private restrooms and employee break rooms. This project is a bigger version with relay to control 220V lights. If 8 wire is what I need for a 40 amp circuit then 10 must be for a 30 amp and 12 must be for a 20 amp and 14 must be for a 15amp.
Suppose that Low light so there is the voltage across the LDR a lot. Why to use relay for controlling AC light. The power supply for the IC is obtained by half wave rectifier D1 a stabilizer circuit D2 and R1 and filter capacitor C1.
Thats probably why the wires for my light circuit get so warm. Required components for this 220V LED circuit. The capacitor C2 in the circuit below gets charge from the main supply.
This automatic staircase light circuit switch on the staircase lights automatically when someone enters on the stairs and gets off after some time. The lamp stays ON for about 1 second and OFF for about 07 seconds. This unit will automatically switch the lights off after a preset delay if no motion is detected.
This problem can be solved with a Schmitt Trigger circuit. Each Sensor employs a special 180 multi-segmented lens and PIR motion detector circuit to detect motion. 12V fan on 230V circuit.
