HC-50 series

Radio measuring system for long distances – no mobile network, no cabling

HC-50 LoRa Sensors

The HC-50 measures where there is no WiFi, no mobile network and often not even power: at wells, ponds, fields or retention basins. The measuring stations (nodes) transmit via LoRa over several kilometres to a base station (gateway). The gateway passes the values on to EcoSensors.cloud via your WiFi, where you see them in the dashboard.

  1. Each node records its readings and then goes straight back to sleep, which saves the battery.
  2. The gateway receives the radio packets of all nodes within its range.
  3. Via your WiFi the values reach EcoSensors.cloud, where they are stored and analysed.
  4. In the dashboard you see trends and current values and are notified when something is unusual.

Key data
Radio technology LoRa on 433 MHz, range typically several kilometres
Topology Star: each node transmits directly to the gateway, simple and reliable
Scaling Practically any number of nodes per gateway, also several gateways in the system
Gateway USB power supply (5 V) and WiFi with internet access, see Power supply
Node Rechargeable LiFePO4 battery, a solar option is in development

Position the gateway so that all nodes can reach it directly. How to do that is described in the gateway guide. What influences the radio range is explained on the page LoRa radio technology. Further information: Firmware features.
