Abstract: India facing one of the major problem is maintenance of street lights. In India street lights are maintained manually, it is found that there is wastage of power by operating the street lights due to manual operations like switch on the lights at day time. Due to that wastage of electricity will be occurred. The methods that are working on the maintenance of street lights are not effective. In this paper a new technique is proposed to control the intensity of LED lights using LDR sensors and PWM drivers resulting in power saving and reducing the manual errors by controlling automatically. Implementation is done using NodeMCU. For effective communication, sending the status of the street lights by using Blynk App for monitoring the street lights effectively.
