Hey,
I'm using the Irms value from the Energy Monitor to control the flow of water from a 12v pump. I want the flow of water to represent the energy being used in my home. I'm sending the Irms value to digital pin 9 which then controls the pump. A schematic of my project can be found at http://alanmeany.wordpress.com/2010/03/01/ambient-energy-monitor-schematic/. The problem is that when the pump starts running it is affecting the Irms value.
Because I am using the Irms value to change the flow of water the value itself does not need to be accurate, it could be any number that changes when appliances are turned on and off.
Would you have any ideas how I could:
(a) Change the code so that the pump does not effect a value being read form the CT Sensor.
OR
(b) Rewire the circuit so that the pump does not effect the Irms value.
