The RS485 to NB-IoT converter is designed for the efficient readings of any device with the RS485 communication, most commonly using the Modbus protocol—such as actuators, electricity meters and other measurement devices. It allows the integration of RS485 devices into an NB-IoT wireless network, facilitating the data collection and analysis at specified intervals.
The converter can be supplied with a power for the sensor or as a communication element without any external power. It is applicable in industrial automation, energy, agriculture or smart city projects.
NB-IoT connectivity – today, the Narrowband IoT coverage is available almost everywhere, with a reach even in hard-to-access areas. Additionally, SIM cards can be obtained for as little as 1 EUR per year.
The antenna connector for the wM-Bus reception is designed to minimize losses, ensuring the highest possible reception sensitivity. As a result, we can cover up to 6 floors, depending on the type of building.
