Receiver circuit
This is a mains powered receiver which listens for the mesh broadcast from the sender unit, translates the data into temperature and depth based upon stored tank parameters and displays the tank fill status on an LCD screen.
There is also an ESP8266-01 module that will be configured as a web server. This will allow a local connection over WiFi for checking oil level from anywhere in the house. Potentially can be used as a logger to give trend info as well as alarms.
The encoder allows parameters such as tank capacity and height to be edited on screen. Once edited the parameters are stored in EEPROM.
