This guide shows how to build cheap data loggers to help keep plants happy in greenhouses or other indoor growing spaces. I developed this design to help a community garden group control temperatures in greenhouses for starting new plants in winter. By charting the temperatures, we were able to identify and fix problems with air sealing and heater thermostat settings. This logger design uses manual data collection over USB serial because there is no WiFi at the greenhouses.
The guide demonstrates how to build a cost-effective greenhouse temperature logger to monitor indoor plant environments, particularly useful for identifying and resolving temperature control issues in greenhouses. It details the process of manual data collection via USB serial in the absence of WiFi, and provides instructions for assembly, installation of CircuitPython, and usage of the logger, including data retrieval and chart creation.
