Monitoring and measuring
- We need to monitor and measure more, to be able to make informed decisions based on facts.
- Here is links, eco related but focused on monitoring
- Temperature
- Power - AMPs and Voltage
- Flow - water
Power measurement - Distribution Board
- Normally the power in a house all flows through a DB (Distribution board) making it the ideal place to measure power.
- Power Watts = Voltage x Current(Amps), for most houses the Voltage is fixed (here 220v) and we only need the current to calculate Watt's.
- Amps are normally measure in two ways.
- Invasive, by having a resistor in series with a circuit and measure voltage drop over the resistor.
- Non-invasive with coil around single wire carrying current, the current induces a magnetic field that induces a voltage in the clamp around the wire.
- Amps are normally measure in two ways.
