sep 24, 2018 before going into the circuit diagram, components and code, i want to talk a little bit about the idea behind the project auto intensity control of street lights using arduino. i won t compare it with any other projects but just dive into the concept.
led solar street lights wiring diagram the solar led street lights are designed for the street lighting demand and fully meets the special requirements of solar street lighting. this product adopt the high power led as the light source, using dozens of high power dmx emitters of 1 watt led.
so it is better to turn off the lamp after 5 or 6 hours using the switch s1. use a small 6 volt 100 ohms pcb relay to make the lamp unit compact. the solar lamp circuit including the relay can be enclosed in a small box. if a reflector is fixed behind the white leds, intensity of light can be increased.
street light that glows on detecting vehicle movement street light that glows on detecting vehicle movement circuit. the proposed circuit is built with atmega microcontroller, ds1307 ic, ldr, lcd, pir sensor, array of led.this circuit is very useful in our day to day life like highways, real time street lights, the parking areas, restaurants and hotels.
these system sizes are based on 100 watt solar panels and 5 hours of average daily sunshine. this is explained in greater detail in our tutorial on solar radiation. of course, under actual operating conditions a solar power system does not produce full output every day. these diagram examples could represent 12, 24, or 48 volts systems.
hi i have a 4 kw solar pv system and i am looking to buy/build a dark/light sensor switch to use as a switch, in line, into the domestic supply to turn on and off an electric oil filled radiator rated 1 or 2 kw, when the solar panels are generating enough power to run the heater.
automatic door opening system circuit. the circuit diagram of an automatic door opening and closing system is shown below.the circuit is built with an arduino uno, 16 2 lcd, pir sensor, connecting wires, bread board, 1 k resistor, power supply, motor driver and dvd. the circuit connection of an automatic door opening system is shown above.

ac circuit for lamp. for switching on and off the lamp we need a control called a switch provided in the live wire between the main supply and lamp. 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.
aug 14, 2017 block diagram of fire alarm circuit using germanium diode. the conduction of germanium diode will start at 70 degrees. so we may use germanium diode as a heat sensor. when the temperature is more than 70 degree, the germanium diode will conduct and trigger the ne555 timer through a transistor.

design and construction of a solar operated automatic street light control system. abstract. in this project work, we are mostly concern about building a simple power streetlight
when the voltage is high enough to engage the relay and the ldr receives enough light in order to open t1, the relay will switch and the battery will charge. the relay remains on even when the solar panel voltage starts to decrease. a connected and charged battery can not action the relay when the light intensity decreases because r2 will block t1.
