One of the disadvantages of an automatic street light is that sometimes it does not turn off when it should. This results in wasted energy and added costs.
The disadvantages of automatic street lights using LDR, light dependent resistor, is the noticeable on/off time difference between sunny and cloudy or rainy days. If the timer is set for a specific time, This concept uses the transistor to operate the on/off switch. If the timer is set for a specific time, the brightness of the light will vary with the amount of light that has fallen.
we can use it in very low light intensity. so that it can save the energy.
it is astable operation to produce clock pulses for the counter
voltage stabilizer advantages and disadvantages
Honestly?! Common sense, if light bulbs were not invented then we would still carry candles with us for light plus no one has to go street to street lighting lamps they're all automatic now.
Street light is good
the disadvantages of street vendors ps hat they do not make fixed profits and they cannot budget for the money tha they get. they depend on people to live
Solar street lights are raised light sources which are powered by solar panels generally mounted on the lighting structure or integrated into the pole itself. The solar panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night. Most solar lights turn on and turn off automatically by sensing outdoor light using solar panel voltage. Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not in the sky for an extended period of time.
The answer is light Light house Star light Street light
Advantages: Plot can be easily subdivided. Disadvantages: Monotonous(regularity)
There is no automatic record of the transaction. It is harder to get back if you are dissatisfied.
helpp meee
