Aiming at the characteristic of street light,a new type of easy street light controller design method is proposed.The method makes use of photosensitive resistor and Schmitt trigger composed of light-control circuit to switch on the street light in the evening,and makes use of capacitor charging and discharging characteristics to control duration of light-time.The overall framework,the hardware circuit and the parameter design were introduced.The feasibility was proved through the circuit simulation and exp...
