Abstract

This paper focuses on an efficient and economical method to minimize electricity wasted by street lamps. The project proposes a wireless sensors based control module to be installed on new or existing street lamps to detect movement of vehicles and pedestrians and thereby turning on the lamps upon detection. The brightness of the lamps can be controlled using a smartphone application. The ‘Smart sensing module’ consists of a set of sensors – PIR sensor, Ultrasonic sensor – to detect and identify moving targets. An LDR sensor keeps track of the ambient light to automatically turn on and turn off the lamps upon nightfall and daybreak respectively. Upon detection of a valid moving target, the module transmits encrypted data over to the adjacent modules using an nRF24L01 radio transceiver module instructing them to turn on the lamps. The lamps turn off after a timeout delay upon no detection. The modules also features a failsafe mechanism to implement conventional lamp operation in case of module failure. A Bluetooth transceiver module equipped only on the master node is used to receive lamp’s active and idle brightness information from the admin via a smartphone. This information is also relayed using the radio transceiver module
