Energy Consumption Monitoring​

A major trend today is the effort to minimize the consumption of electricity, gas, or water. The Internet of Things (IoT) enables real-time monitoring and regulation of energy usage.

Monitoring Electricity Consumption​

Electric current can be measured using two basic methods:

  1. Direct Measurement – using an ammeter, which measures the magnitude of electric current in a circuit.
  2. Indirect Measurement – the electric current is not measured directly, but instead another physical quantity is measured, from which the current and consumption values can be calculated.

Options for Indirect Measurement of Electric Current:​

Pulse monitoring​

One of the ways to monitor consumption online is by connecting to electricity/gas/water meters and transmitting the number of pulses these meters generate depending on the consumption of the respective medium.

The most commonly used sensors for pulse monitoring are:​

  • LED sensor – detects LED pulses on the meter, which blink to indicate consumption
  • Magnetic sensor – detects pulses generated with each rotation of a magnet placed on the unit dial
