Brooklyn Grange Water Level Sensor

A small microcontroller inside a waterproof transparent plastic HUBBELL cover with a thick black cable and thin black, yellow and red cables attached. The microcontroller is secured to the side of a white plastic bin.

Brooklyn Grange operates 2 beautiful rooftop farms in Brooklyn, NY. In response to an incident where an automated aquaponics system experienced an undetected water tank leak, I created a simple sensor to actively monitor the water level and send email alerts when the water level drops below a certain threshold.
