Remote street light monitoring and control system for energy conservation in street lighting

Smart Street
By Instruments Universal

Overview
Energy saving is the main issue in this era.
At town and city level Street Lights consumes very
high electrical energy per minutes.
There are much scope of energy saving in street lighting
systems as under
 Design base lighting as per road size & traffic
conditions
 Use latest lighting products
 Automation in street lighting systems

Overview
In Third category following products are available
Electromechanical timer
Disadvantage
 Fortnightly Time setting required
 Exposed to dust affect the performance
 Battery required to be replaced
 Low resolution – 12 minutes

Overview
Photo cell operated switch
Disadvantage
 Dust, clouds & birds affect the performance – leads to
mal functioning of product
 Periodically sensor required to be cleaned.
 Photo sensor ageing problem.
 Manual interaction required

Overview
Programmable time switch
Disadvantage
 It operate on preset program of 15 days
 Selection of battery for RTC (Battery life less then two
years.)
