HOW THE OWL MICRO WORKS
Overview
This measurement category II product uses current transformer sensing technology to detect and monitor a tiny magnetic field around your
household electricity power cable. It measures the current (Amps) being used and, by reference to the system voltage, calculates the amount of
power being used and the cost. It then transmits this information from the Transmitter wirelessly to the Display on a radio frequency of 433MHz,
from up to 30 metres (100 feet) away (unbroken transmission).
NOTE
The intention of this product is primarily as an educational device to aid understanding of the cost of operating electrical
appliances in the home. Hence, there is no intention for the Micro Wireless Electricity Monitor to replace your accurate electricity revenue
meter.
Household Power Cables And Phase
Most UK household electricity supplies use single-phase, but some use three phase. In single-phase supplies, the current flows to and from
your household appliances using a neutral and power line. The neutral line has a voltage close to zero while the power line carries a fluctuating
voltage or phase. The difference between these two lines makes the current flow through your appliances.
In three phase supplies, current flows to and from a device through a group of three lines - each one carrying a fluctuating voltage or phase. For
3 phase supplies our Wireless Electricity Monitor is required with a sensor connected to each of the three phase lines.
Accuracy
The Micro Wireless Electricity Monitor has a fixed voltage - 230V and used with the monitoring of current by the sensor clip enables a
calculation of KWH. Generally the device is accurate within 10%. The Micro Wireless Electricity Monitor is not designed to replace homes
electricity meter - they are aimed to provide a very visual and accessible way for users to see the impact of different devices and usage patterns
around the home. This we hope will assist in educating users to adopt more beneficial consumption habits, reduce their costs and reduce their
carbon emissions.
