Climate Minder Wireless Nodes/Stations

The ClimateMinder wireless network is a collection of nodes, each of which is able to communicate with the other nodes using a proprietary Rain Bird radio module. Each node or station monitors sensors attached to it, communicating this data to the Gateway. The Gateway station is the node that communicates with the ClimateMinder Server using a cellular modem.

Each node or station is a weather-proofed enclosure containing the hardware components required for its task, possibly including: wireless radio, external antenna, battery, interface module, power module, and cellular modem.

Nodes form a self-configuring network (when the device is switched on, it introduces itself to the network and finds its neighbors to send data), that is also self-healing (if a node is broken along the route, other nodes route information through another path), and is optimized for low power operation.

There are 3 kinds of nodes:

  • Wireless sensor node: This device monitors up to eight attached sensors.
  • 8-way controller: This device has eight relay outputs.
  • Gateway: This device communicates with the ClimateMinder Server using cell networks and can include variety of sensors.

Technical Specifications for each node:

  • RF Frequency: 2.4 GHz (IEEE 802.15.4)
  • Communication Protocol: GrowFlex™
  • Outdoor Range Per Single Hop: typically 2,500 ft., with line of sight
  • Batteries:
    • 12V Sealed Lead Acid Battery
  • Solar Panel:
    • Gateway: 20W
    • Wireless Station: 5W
