auto intensity control of street lights using arduino
sep 24, 2018 basically, there are two modes of operation of this project rtc mode and ldr mode. in rtc mode, the street lights turn on automatically based on the on time set in the code and turn off based on the off time. in the ldr mode, the street lights have an intensity control based on the ambient light near the ldr. circuit diagram
solar charge controller working using microcontroller
solar charge controller circuit using microcontroller. solar charge controller plays a prominent role in the solar powered lighting systems based on the system overall performance. solar powered lighting systems are made available in urban and rural areas. these include solar street lights, solar home
automatic street light controller circuit using relays and ldr
the circuit uses a light dependent resistor (ldr) to sense the light .when there is light the resistance of ldr will be low. so the voltage drop across pot r2 will be high.this keeps the transistor q1 on. the collector of q1(bc107) is coupled to base of q2(sl100). so q2 will be off and so do the relay. the bulb will remain off.
