this circuit senses the ambience light and depending on the presence/absense of sufficient ambience light, it turnes the bulb on/off automatically. the bulb gets on when there is insufficient ambience light (e.g evening or night time) and switches off automatically when enough ambience light is present.
since the entire experiment depends on the working of the ne 555 timer, it was necessary at first to check the functioning of the timer using a cro. design implementation. figure 1 block diagram figure 2 implementation using ics. astable configuration the 1st 555 timer was set in astable mode.
ldo solar charge control circuit operation. r4 and d1 form a 6v shunt zener voltage reference. q1 & q2 make up the classic differential amplifier that amplifies the difference between the reference voltage and the feedback voltage from the arm of potentiometer r6. the output is taken from the collector of q1 and drives the gate of p channel mosfet q3.
nov 01, 2013 the ldr circuit diagram works like this when it s light, the ldr has low resistance. this makes the voltage at the base of the transistor higher. high enough to turn the transistor on. because the transistor is turned on, current flows through the transistor. it flows from the positive battery terminal, through r1, the led, and the transistor down to the negative battery terminal.
a light sensor generates an output signal indicating the intensity of light by measuring the radiant energy that exists in a very narrow range of frequencies basically called light , and which ranges in frequency from infra red to visible up to ultraviolet light spectrum.. the light sensor is a passive devices that convert this light energy whether visible or in

a street light, light pole, lamppost, street lamp, light standard or lamp standard is a raised source of light on the edge of a road or path. when urban electric power distribution became ubiquitous in developed countries in the 20th century, lights for urban streets followed, or sometimes led.
we would like to provide you with a huge list of electronics mini project ideas for your engineering project work, along with the components list, circuit diagram, code, working principle, and applications. this list has a combination of our own making diy projects and a
block diagram. during the day time solar energy from the photo voltaic cell is charged to the battery by charging control circuit. under and overvoltage protections to the battery are also included in this circuit. pulse width modulation is implemented in the microcontroller program so that it drives the mosfet which is connected to a group of led s.
ir based light control this circuit turns on the lights at the portico, car parking or other areas when a motorbike or car enters through the gate to cross the sensing area.
if the switch is on, the electric circuit is closed and the lamp glows, and if the switch is off, it will disconnect the power supply to the lamp. for safe operation this wiring is placed in a box called a switch box. the switch wire and live wire are a single wire; it is just cut in between to connect the switch.
