Water Rat

Farmo's Water Rat (patent pending) is the best and easiest to set-up tank and trough water sensor on the market. Just throw it in the trough, or tether it to a tank, and get low water level alerts on your phone or PC.

How it works

The Water Rat looks simple but has some smart technology inside, including an accelerometer tilt sensor to detect movement and a NB-IoT module to send data. When the water level reaches a low point, the Water Rat tilts over and sends an alert. When the water level rises and the Water Rat regains position, another alert is sent to let you know the water level is okay again.

Pricing model

Water Rat is $749 inc GST. Ongoing costs are $132/year which includes data, access to the Farmo dashboard and alerts to your phone or PC.

Installation process

Throw the Water Rat in your trough and walk away - it's that easy. Or for tanks, tether the Water Rat to the side of the tank and start receiving alerts as soon as the water level drops to the point where the Water Rat tips over.

Ongoing maintenance required and support provided in Australia

Wipe down and clean the Water Rat occasionally to keep it in best condition.
