Room For Improvement

From the prototype above, following observations were made 

• The LED was not bright and clearly visible through the membrane material.
• The membrane movement was not easily noticeable.
• The soil moisture reading was not displayed on console or made available online.

These improvement opportunities were worked on and implemented on the final prototype.

Final Prototype

The aesthetics of the prototype was improved for better visibility of the membrane movement and the LED light. Also, a touch button was incorporated which will send the real-time moisture value  reading on to an online spreadsheet.
