Harvy2 - Battery-free LoRaWAN current sensor

Our sensor with four inputs for versatile monitoring

Unlike common LoRaWAN sensors, it does not require a battery or external power supply.
Once installed, the battery-free LoRaWAN sensor runs autonomously and maintenance-free. This IoT sensor draws the energy it needs for operation from the magnetic field at the electrical conductor: it is sufficient to have an average current of 1 A flowing through one of the monitored wires. The principle behind it: Energy Harvesting.

One typical application of the Harvy2 is the metering of RMS currents in electrical mains, sub-distribution boards, or directly from the machines. Simply connect (up to) four deZem clamp-on current transformers to the Harvy2 current sensor and fold around the desired current cores - done! In addition, when using a deZem voltage transformer, the Harvy2 sensor is also able to determine the active power and many other measured values for all three three-phase current phases. With the Harvy2 in the Rogowski edition , even higher currents up to 120,000 amperes can be captured. Data from the sensor is transmitted to any IoT platform for visualisation and use, making it the ideal complement to our IoT solutions.

An intelligent event filter** is integrated into the current sensor, which, for example, maps the inrush currents of systems accurately to the second. Alternatively, metering values can also be read out in a fixed time grid - even synchronously for metering values distributed anywhere in the world. All parameters may also be configured and firmware updates may be installed via an intuitive web interface. Decoders are provided by deZem for various IoT platforms.
