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.
