who is watching your tomatoes?

Temperature sensors for your greenhouses and other spaces

Meet the green canary - a reliable automated monitoring system which will notify you if the temperature of your space gets too low or too high.


Where do the green canaries work?

Any United States location where there is a standard electrical outlet and Verizon cell phone coverage.

Simple to get and install

Register at our web site and order one or more sensors.

We ship the sensor.

You plug it in, then configure it at our web site.

And you're ready!


How do the green canaries work?

Each sensor sends temperature readings to our servers over Verizon's cellular network. Our servers will notify you if the temperature gets too high or low.

OK - but how do the green canaries REALLY work?
