## Choosing Sensors 

Often the first step is to look for a sensor for what you're hoping to measure. Below we're collecting info on different kinds of water quality sensors, and their:

* cost
* sensitivity/accuracy
* links and documentation

Can you afford a sensor? Can it detect what you're looking for? Where can you learn more about it?
