Particle Photon Salinity Meter

We made a measurement device to measure the salinity of water using a magnetic field and a linear hall sensor.To make it we used a Particle Photon, but an Arduino could also be used as they work practically the same way.
To make this project you need a couple of things:

- Particle/arduino including a breadboard and some cables
- a linear hall sensor
- some magnets(we used small but strong neodymium magnets)
- a pen
- some tape”
