Please watch the following videos for inspiration for your machine.

Automatic Plant Manager

In this activity, you will be creating a plant management installation that will monitor the plant for temperature, humidity, and sunlight on a potted plant.

Sensors needed:

• Light dependent resistor

• Temperature and Humidity sensor (TinkerCAD projects should just use a temperature sensor)

• Pushbutton to manually activate water valve.

Outputs needed:

Intermediate Level

• LCD Display showing temperature, light level, humidity level(if applicable).

• Servo motor (simulates a valve for water)

• LED's representing too much/little light and temperature.

Advanced Level

• LCD Display showing temperature, light level, humidity level 

• Stepper Motor (simulates a valve for water). For TinkerCAD projects, use 2 servos.

• Piezobuzzer alarm for too much/little light and temperature.

• Relay + DC Motor fan activated when temperature is too high.

Deliverables

For this project you are to keep a project log. It must include:

• A Timesheet for all group members working on this project. A sample can be found here.

• An engineering journal that chronicles the following: (please update daily)

  • When planning out this project what kinds of drawings and schematics did you use to plan the circuits and code?

  • What challenges did you face and how did you overcome them?

  • What advice would you give the next students to try this project?

  • What real-world applications does this device have?

• A final project video demonstrating your machine.

File all of these things in your ePortfolio. A public link to that will be submitted to d2L when you have completed the project.
