At a public school, three different energy production methods must be established for teaching use:
- A solar cell (approx. 1 m2)
- A windmill (also very small)
- An exercise bike
The electricity produced is stored on a battery, from which the students can use it to drive water pumps etc.
We would like to measure the electricity production and consumption in a way where data is sent every second (or at least every 5 seconds) to an API (which we would like to make ourselves if necessary) so that data can be stored in a database.
We prefer that we measure everywhere with the same kind of hardware, so that we don't have to integrate for different ways of getting this data.
We therefore imagine that we will find an electricity meter that we can connect to each device - the solar cell, the bicycle, the wind turbine, the water pump (so that the electricity produced or consumed flows through the meter). And then this meter is online (WiFi is available) and calls the API with its data.
My question is 'simply': What hardware products exist for this?
Hope it makes sense. Or else; ask!
