Node Pi


 

The NODE Pi is at the heart of the NODE Grow App system. Built using the Raspberry Pi 3 single-board computer and a wide range of 3rd-party sensors and relays, the Node Pi is the first truly affordable and reliable crop automation system on the market. The NODE Pi is designed to be used with the NODE Grow App, i.e NODE Labs.

Currently, we are working providing 3 models of the NODE Pi:

  1. Root Model
  2. Home-Edition Model
  3. Professional Model

Every model includes with a Raspberry Pi 3 and come with an 8-gigabyte SD card preinstalled with NODE source code, a 5v power adapter and a case with a swivel mount for easy installation.
