This project uses a hall-effect / flow-sensor to report the current volume of water being received by my washing-machine. every minute.
The information will be published to a MQQ / Mosquitto server on the
topic water. Additionally the board will dump all its meta-info
to the topic meta on startup.
The meta-information includes:
- Hostname
- IP Address
- MAC Address
- etc.
You'll need to change the IP address of the MQQ server if you wish to deploy this yourself.
The flow-sensor is wired to pin D2, which is hardwired.
