TrustLink is a Main/Solar Powered Data Concentrator device for collecting and transmitting data via multi-wireless data transmission technology like LoRaWAN, NBIOT and GSM with multi-interfaces protocol support (DLMS, EURIDIS, MBUS), analog input, digital input (guard or pulse counter or 4-20 mA), wireles M-Bus, I2C and open collector.

It is used to collect and transmit readings from various kinds of metering devices, sensors (temperature, pressure, smoke, alarm status, etc.), industrial equipment.

The device will collect and transmit data via the wireless data transmission network to an analytical platform.

The device comes with LoRaWAN, NB-IOT and GSM/3G/4G antenna.

Operating Principle

Utility Meters (Electricity, Water & Gas) are connected to the device, the received data is transmitted wirelessly via the multi-wireless data transmission technology like LoRaWAN, NBIOT, or GSM to the gateway or base station of the utility company with subsequent data transfer to the local server or cloud storage.

Multi-Sensor Device

Temperature sensor, Pressure Sensor, Built-in Meter Sensors, Humidity Sensor, Smoke Sensor, Motion Sensor are only a few sensors that TrustLink can support. The data readings from the sensors are transmitted via the multi-wireless communication data technology. After receiving this data and checking the checksums, sends the data unchanged via the network to the server.


TrustLink (DC-100) Main/Solar Powered Data Concentrator data collection and transmission device is a ready-made solution for utility meters (electricity, water & gas)

Data transmission over the Multi-Wireless Communication technologies (LoRaWAN, NB-IOT, LTE/3G/2G, Wireless M-Bus)

It can be equipped with an additional expansion board

Housing Utilities

The solution is suitable for residential buildings, apartments or neighborhoods. Installing the TrustLink Data Concentrator on apartment-by-apartment metering devices will allow you to automatically receive readings remotely by the utility companies.

Accounting for Industrial Resources

The device for collecting and transmitting data can be attributed to an element of the pipeline telemechanics system. The device solves the issues of transmitting information about pressure, flow rate, temperature and other parameters.

Environmental Monitoring

Additional control of parameters (temperature, magnetic influence, humidity, etc.)
