Electricity usage monitor

The Cent-a-meter is an electricity monitor that provides users with details on the cost of operating electrical appliances to help control and conserve energy use. It also provides information on equivalent greenhouse gas emissions, and temperature and humidity levels.

The unit consists of a sensor, wireless transmitter and receiver. The sensor and transmitter are installed in the electrical switchboard. The readings collected are relayed by the transmitter to the LCD monitor located inside the office. The monitor displays power consumption, cost per hour of electricity, equivalent greenhouse gas generated, indoor ambient temperature and humidity. Settings and display modes can be viewed and changed by a push-button menu. Multiple monitors can be used in different locations for a single transmitter.

The unit features an alarm which is designed to help users manage peak power consumption and can be set to activate when power usage and cost exceeds a predefined amount.

Installation is easy wireless technology and a clip-on sensor to ensure no interruption of supply; however, it must be installed by a licensed electrician.

It is not an accumulation revenue meter; therefore, it cannot be used as a check on electricity bills. It can, however, be used to monitor individual circuits of metered premises to estimate a division of power use.
