week 8 FYP2

Objective
1. Formula that need be upload coding acs712 and 

Discussion 
1. Voltage is measured by the help of a voltage divider circuit.As the ARDUINO analog pin input voltage is
restricted to 5V 

2. Formula need to be implemented which Power and Energy.

Power

Power is product of voltage (volt) and current (Amp)
P=VxI
Unit of power is Watt or KW

Energy is product of power (watt) and time (Hour)
E= Pxt
Unit of Energy is Watt Hour or Kilowatt Hour (kWh

From the above formula it is clear that to measure Energy we need three parameters
- Voltage
-Current 
-Time
