MeshCoyote is a multipoint measurement system. It uses mesh network topology to carry all node measurements to a single recorder or data forwarder.
For now the project only measure temperature but this will soon be extended to Power usage, Voltage, Current, Anemometer etc.
A "node" is a single device where a measurement is made. All nodes are able to communicate with each other to carry al messages to the master node. This master node (or recorder node) is able to save the data locally or forward them to any other database such as Emoncms, Influxdb or else.
Mesh technology offer the possibility to greatly extend communication range. Every node is a repeater to allow communication between the recorder and a node spatially located out of the direct path range of the recorder.
MeshCoyote uses radio transmitters nrf24l01. RF24 for a short name.
All communications are self organised. The network builds itself using every reachable neighbours. If a node is moved the network is able to re-organise itself around the new topology.
We propose two types of hardware. Sensor nodes and recording node.
We have designed the NanoRF24 which is a hosting board for Arduino Nano and RF24.
The RPIRF24 has been designed to adapt a RF24 module onto a Raspberrypi. The Raspberrypi is an ideal solution as a recording or forwarding module.
