eGreenhouse is a lightweight and low-cost greenhouse sensor package integrated with the OPEnS HyperRail. The sensors travel through the greenhouse and transmit a live stream of data to Google Sheets.
Check out the Wiki Page or OPEnS-Lab-Home-Page. I would recommend checking out both links to get the idea.
