Camera Specs:
- Focal Length: standard (40-70mm)
- Min/Max Zoom: 5-10x
- Resolution: 1600x1200 pixels
- Aspect Ratio:
- Field of View:
- Other: must be in colour (preferably maintaining original appearance)
Note: none of these are hard guidelines for the camera, something that is HD, is in colour, and can zoom in will work

Soil Moisture (b) 3 https://www.dfrobot.com/product-599.html 60x20x5mm (2.36x0.79x0.2") Double probe, resistive measurement. Only one moisture sensor is required, both are presented because of sizes. Y 3. pH 30
dfrobot.com/product-1025.htmlThis test can also be done manually(ex. litmus test) if mech/electrical have a preference. Y 4. CO2 56 https://store.arduino.cc/usa/gravity-analog-co2-gas-sensor 32x42mm (1.26x1.65") Most CO2 soil sensors are required to be fixed to the ground and are larger (have their own container for soil collection). If this is viable for mechanical team, the following sensor can be looked into: https://www.campbellsci.ca/eosfd Y 5.
