Uses

LED Display, pins

Description

In this project, you will be making a soil moisture detection program using a soil moisture module, or 2 crocodile clips and 2 long nails.

Plants need water to survive, and to monitor whether we need to water the plants we need a soil moisture detection apparatus. It checks for moisture in the soil and displays on the led whether it is time to water the plants.

Basic Task

  1. Make sure that the soil moisture module or the makeshift one is connected.
  2. Check the pin0 for analog reading, and try to compare when the soil moisture module is in water and off water. Might need to take several observations to come up with an optimal threshold value.
  3. Display on LED an image to indicate that you needs water the plants if reading is above the threshold value, and display another image if soil moisture is still enough for plants.
