I have experimented a little using the MCP3008 to read current from a smaller and simpler Hall effect current sensor. For some application 10 bit is enough and the MCP3008 has 8 single ended channels and 4 if used differential. Differential measurements makes more sense for these type of current sensors.
The MCP3008 can also be used for voltage measurements and for this type a single ended measurement is quite ok, it also provide twice as many channels.
The current measurement is documented at my project pages :

Please feel free to include any of this content in the Openplotter pages. Some day I'll try to find time and energy to include the MCP3008 in the Openplotter code in a similar way as ADS1115 in differential mode, including some contribution to the Openplotter documentation.

Ole
