Environmental monitoring web app for gardens, greenhouses, and fish tanks. Using a Raspberry Pi and drivers for Bosch I2C sensors, Atlas Scientific I2C sensors and peristaltic pumps, and PWM controlled fans, a garden, greenhouse, or fish tank can be monitored and controlled from any web-capable device.

This project is in the early stages of development. The hardware drivers for the Bosch BMP280/BME280 environmental sensor, Atlas Scientific devices, and sensors supported by lm-sensors are mostly complete. The web-based user interface is currently the main development focus, and currently has limited useability (output of sensor data is the only feature currently supported).

• Drivers
  • Add PWM controller for fans and other PWM controlled devices.
  • Update other drivers to depend on same library as the PWM controller.
  • Add missing functionality to the AtlasScientfic driver.
    • Support for temperature, pH, electrical conductivity, oxygen reduction potential, and dissolved oxygen sensors are mostly complete, but not fully tested. Support for other devices is limited to basic functions.
  • Add a soil moisture driver.
    • Vegetronix VH400 is one hardware option.
    • Here is another option.
    • Here is one more option.
  • Add a driver for using a webcam to produce still and time-lapse style video of the garden.
• User Interface
  • Add configuration user interface with authentication.
  • Create a theme and make the UI nice to look at.
  • Use websockets to update data display. Alternatively, auto-refresh the page periodicaly.
• General
  • Add unit conversion.
  • Add support for responding to events (e.g., increase fan speed if air temperature gets too high).
  • Rework device command queue to be more responsive.
  • Fix the shutdown sequence.
• Documentation
  • Document config.json.
  • Add installation instructions.
