1.	The automatic switching and control of street lights can save energy The device used to achieve this can be a) Astronomical TImers b) Thermostats c) Manual switches d) None of these
Answer» The correct answer is option b - THERMOSTATS. A thermostat is a component which senses the temperature of a SYSTEM so that the system's temperature is maintained near a desired setpoint. These thermostats can detect if it is day or night depending on the solar temperature in the atmosphere and can be automatically switched on and off. Also, many SENSORS like occupancy sensors, motion detector, occupancy sensors, and other ULTRASONIC DEVICES can be for Smart-lighting and for auto intensity control of street lights.
