Determining a Plant’s Health with TinyML
The brain of this project is the Arduino Nano 33 BLE Sense, and it was chosen for several reasons. First, it has a rich set of powerful sensors, including a 9DoF IMU, APDS-9960 (color, gesture, proximity, and brightness), microphone, and a temperature/humidity/pressure sensor combo. In order to move the board around the plant’s leaf and take measurements, a pair of stepper motors are used in conjunction with a pair of DRV8825 driver boards.
