Prepaid meter and energy
conservation

2. INTRODUCTION
• The prepaid energy meter technology is already established in
the market. The government is giving the opportunity to use
this in houses.
• We ended up making system where one can recharge in their
meter using pin code. And can see the reading of the meter
from SMS.
• And if meter needs recharge it will give warning to the user. If
user doesn’t recharge in time. It will shut down the system.
And if will start again when it will be recharged again.

3. PROPOSED SYSTEM
 Implementation of Prepaid Energy
Meter Technology.
 Read energy consumed by the load
from Energy Meter.
 Make a recharge system based on
sample codes.
 Calculate amount of expense for the
energy consumed.

4. Opportunity to receive SMS about expense of energy used and
remaining amount of unit in meter.
Warning message given to the user for recharging warning.
Shut down the system if user doesn’t recharge in time

5. MAIN COMPONENTS
1. Arduino Uno
2. Relay Module
3. GSM SSM 900
v3.8.2
4. Load [ 100W
bulb]
5. Energy Meter
6. Jumper wire

6. WORKING
 Reads energy meter and save in an input Pulse.
 Process calculations based on the tariff rates and save the new
balance .
 GSM send the meter reading and balance amount
 Receive recharge requests and change in tariff rates if any

7. AUTOMATIC STREETLIGHTS
Our manuscript aims to develop a system which will
lead to energy conservation and by doing so, we
would be able to lighten few more homes.
The proposed work is accomplished by using Arduino
microcontroller and sensors that will control the
electricity based on night and object's detection.

8. The beauty of the proposed work is that the wastage of unused
electricity can be reduced, lifetime of the streetlights gets enhance
because the lights do not stay ON during the whole night, and also
helps to increase safety measurements.
We are confident that the proposed idea will be beneficial in the
future applications of microcontrollers and sensors etc

9. COMPONENTS
Components
1. LDR
2. Arduino Uno
3. LEDs
4. Resistors
Specifications
Voltage: DC 3-5V, 5mm,1.8 gm
22 pins, operating voltage 6-20V
5 mm , operating voltage 5V
100 ohm, 220 ohm

10. LIGHT DEPENDENT RESISTOR (LDR)
• LDR is a Light Dependent Resistor whose resistance is
dependent on the light impinging on it. The resistance
offered by the sensor decreases with the increase in
light strength and increases with the decrease in light
strength.

11. ARDUINO UNO
• Arduino Uno is a microcontroller board which is
based on the ATmega328 series controllers and has
an IDE (Integrated Development Environment) for
writing, compiling and uploading codes to the
microcontroller.

12. LEDS
• A LED (light-emitting diode) is a PN junction diode which is used for
emitting visible light when it is activated, as presented in When the
voltage is applied over its elements, electrons regroup with holes
within the LED, releasing energy in the form of photons which gives
the visible light. LEDs may have the Dim/full capability

13. RESISTORS
• Resistors A resistor is a passive electronic component, used with
other electronic components such as LEDs and sensors to prevent or
limit the flow of electrons through them as illustrated in . It works on
the principle of Ohm’s law which prevent overflow of voltage.

14. DESIGNING METHODOLOGY
Circuit design of automatic street light
control system with the Dim light
capability.

15. WORKING
• One leg of LDR sensor is connected to Arduino analog
pin number A0 and another leg to VCC pin and same
with a resistor to the ground port of Arduino.
• In addition, the threshold value is adjusted to 10 from
the discrete values (0-1023) for understanding
whether it is day or night.

16. • After that, all the positive terminals of the LEDs are connected with
resistors to pin number 3, 5, 7, 8, 9 and 11, depicting the streetlights
as the outputs of the Arduino signals.
• Furthermore, connected the ground of all the LED’s to Ground port as
per the circuit diagram The IR obstacle avoidance sensors are
connected to the Arduino port from pin number 2, 4 and 10,
respectively, which is the input signal to the Arduino board.

17. • After connecting all these devices to the corresponding pins in
Arduino according to the Arduino Software from the official
website “www.arduino.cc” is downloaded and installed. Then
Arduino Uno is connected to the computer using the USB
cable and installed the driver software on the computer to
write, compile and run the software code on Arduino software.

26. CONCLUSION
• The proposed streetlight automation system is a cost
effective and the safest way to reduce power
consumption. It helps us to get rid of today's world
problems of manual switching and most importantly,
primary cost and maintenance can be decreased
easily. The LED consumes less energy with cool-white
light emission and has a better life than high energy
consuming lamps.

27. • Moving to the new & renewable energy sources, this system can be
upgraded by replacing conventional LED modules with the solar-
based LED modules. With these efficient reasons, this presented work
has more advantages which can overcome the present limitations.
• Keep in mind that these long-term benefits; the starting cost would
never be a problem because the return time of investment is very
less. This system can be easily implemented in street lights, smart
cities, home automation, agriculture field monitoring, timely
automated lights, parking lights of hospitals, malls, airport,
universities and industries etc.
