* As the theme of this design challenge goes, this project focuses on the sustainability of mankind in case of a global disaster or that of an interplanetary voyage.
* The project is developed to have an autonomous self-contained system for plant cultivation so that the least human intervention is required for maintenance.
* It is not only small in terms if footprint size, but it will be so small that multiple of these can be developed with ease and be put in various congested spaces within the cultivation area.
Hardware requirements:
----------------------------------------
* Raspberry Pi 4 2GB
* Rpi Cam
* Pimoroni PIM487 Automation HAT
* PIM486 Enviro HAT
* PICO HAT Hacker PCB
* Micro water pump
* Microheater
* LED light strip
* power cable & splitter
Software requirements:
---------------------------------------
* Python
* MQTT
Working:
---------------
* The PIM486 Enviro HAT monitors the temperature, pressure, humidity, and light inside the cultivation area.
* Rpi 4 running an RTOS receives the data from the PIM486 Enviro HAT and controls the PIM487 Automation HAT.
* The Rpi cam attached to Rpi 4 tracks and detects any illness to the crops via ML models (trained prior for the particular crop variety)
* As per instructions from the Rpi 4, PIM487 Automation HAT will control the water pump, sprinkler, temperature gauge, lighting, etc to adjust the ambient environment for ideal growing conditions for the plant.
* The Rpi also hosts an onboard server capable of storing the data onboard or to the cloud for remote monitoring via MQTT topics.
* Rpi also allows remote control of the actuators via the automation HAT.
* PIM487 Automation HAT OLED displays the realtime status of the monitored environment.
* To save energy, wake-up detection can be included in the mic to detect human presence to activate the OLED and switch off when no human presence is around.
