Order and Pricing Info

“The provided instructions made for a simple, hassle-free installation and the sensor required zero maintenance following the initial deployment. This was a significant time and budget saver for our project and the results were remarkably accurate.

It really has been a dream to work with the Hyfi sensors.  I will be looking to use them again as much as I can where it makes sense.”
