MargDeep

MargDeep – LoRaWAN Light Control Unit​

MargDeep is a Light Control Unit (LCU). It is an add-on control unit that brings connectivity electrical energy measurement and luminosity control to any standard dim-able street light luminaries.
It has interfaces for light dimming control, communication modules and multiple sensors – enabling the system integrator to work with any vendor and make of LED luminaries. The system is designed to be radio agnostic to interface any proprietary or open networking radio modules. MargDeep has variants with higher Tx power +27dBm for longer range and lower Tx power +19dBm for power constrained systems.
