This part of the project is to build an alarm system for water toxicity. Specifically, we're implementing it with NaCl (salt) in this case. We expect the alarm to go off when the salt is added to the water.
The alarm didn't go off in this video because the sensors/probes were not touching the water(not enough water in the container or the sensors could be lowered). Watch our "Final Project Demonstration" video for the complete version.
