25 meter HypeRail + eGreenhouse

Posted on by

Abstract: The HyperRail was modified to be used with the eGreenhouse, a sensor suite for real-time greenhouse monitoring. The system is about 25.5 meters long and is located in the Northwest Research Extension Center in Wilsonville, OR.

Deployment: The HyperRail has the standard setup of electronics, but in this iteration it includes a short range radio. This radio is used to upload the data from the sensors up to a google spreadsheet. Here is a link to eGreenhouse page that details the the setup of the sensors.

The full-scale deployment has been successfully tested on a 25-meter OPEnS HyperRail. The full transmission sequence was verified from hub to sensor node, back to the hub, then relayed to an ethernet hub over 100 meters away. CO2 and other sensor data was sent from the greenhouse to Google Sheets and plotted in real time.

Three nRF transmission boards are under testing for reliability and range (Itead, SparkFun, Amazon). When the nRF is proven stable, the deployment will start running continuously with the help of a wireless charger.

More updates to follow in January 2019 with a live data feed from Google Sheets.
