Each has the room name set as the machine’s hostname. The following uses three physical Pi Zeros setup in the following configuration. So when a client hears it, it knows where to send it’s temperature data. The server’s broadcast message includes the servers address. When clients start up, they wait to hear the broadcast and perform a basic handshake. The server broadcasts it’s address over the network. So, if you have a machine in the office, change the hostname (via raspi-config) to office. All temperatures will be graphed.īy convention, each machine will identify itself by it’s hostname. This is so that you can get an average temperature for the room (say, placing one sensor high in the room and another at floor level) or up to five individual temperatures. The hub itself should be connected to a temperature sensor.Įach Pi can have up to five physical sensors attached. One Pi acts as the hub or server whilst additional machines act as clients and upload their temperature data to the hub. The temperature-machine can run on one or more Raspberry Pis connected to one or more temperature sensors. You can track ambient temperature over days, weeks and months and display some pretty graphs.

The temperature-machine is a low cost, do-it-yourself data logger built around the Raspberry Pi and the DS18D20 temperature sensor.
