The ClimateMinder wireless mesh network is a collection of nodes, each of which is able to communicate with the other nodes using a radio module. One or more sensors or control relays are connected to each node. Each node controls whatever sensors and relays are attached to it, communicating sensor and control data to and from the Gateway mode. The Gateway node is the node that communicates with the ClimateMinder Server using a GSM modem.
Each node is a weather-proofed enclosure containing the hardware components required for its task, possibly including: mesh radio, external antenna, battery, interface module, power module, GSM radio, and node controller.
Nodes form a self-configuring network (when the device is swithed on, it introduces itself to the network and finds its neighboors 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.
Sensor and control node. This device controls up to four attached sensors and/or one relay. 
8-way controller. This device has eight relay outputs and eight contact inputs. 
Gateway node. This device communicates with the ClimateMinder Server and includes one temperature/humidity sensor and one relay.
