Radio module, for data acquisition and transmission with Narrow-Band technology at programmable frequency (UHF), or 3-4G, or SMS (GSM/GPRS), able to read digital and analogue electrical signals, at very high resolution. Data are then processed, and can be sent directly to a cloud platform, or through point-to-point connections, or networks with specific protocol (SigFox, LoRa, Socket, MQTT etc.) be forwarded to gateways up to a distance of several kilometers between transmitters and receiver (gateway).
The device is configurable to send data at specific intervals and reads signals in current, voltage, Pt100, status and frequency.
