Automatic Street Lightning System With PIR
Energy consumption due to street lights needs proper monitoring and control to reduce wastage of power. Conventional street light systems suffer from certain drawbacks as they are manually controlled and are powered through the electrical broad power station. This may lead to more power consumption if not monitored properly. The automatic street lightning system that we have implemented provides automatic control and fault detection of street lights and to monitor the typical situations occurring in the walkway. The ON/OFF condition of street lamp is controlled using LDR sensor and brightness of the lamp is controlled using IR sensor. If there is any malfunctioning in the street lamp the relay senses and generates a signal to the authority using IOT. The system also provides security alerts using Digital cam. Hardware implementation has been done and the results are also provided .
