TOPICS

WIRING6

1. Set up the humidity level of the soil based on the ideal humdity level of a plant, Ex : 78,20%

2. When the plant humidity is enough,then the red light will be turned on, and the AC pump will be turned off

3. If the soil humidity level less than its requirement, then automatically the red light will be switched off.

4. The green light and the AC Pump switch on

5. After the humidity level is achieved , the AC pump will be turned off as well as the green light

3. SENSOR YL-69 This is a simple water sensor can be used to

detect soil moisture when the soil moisture deficit module outputs a high level, and vice versa output low. Use this sensor produced an automatic plant watering device, so that the plants in your garden without people to manage.

How The Program’s Work ?

In the program it written if we have the threshold value and the threshold value is 800 (based on which plant we choose) as Thus, when the value detected by the sensor shows less than the threshold value , the red LED will shut down or Off. Menawhile, green LED and the pumps would turn on. That indicates that the plant needs to fertilization. In reverse, when the value hits more than the mentioned value or equal to that, red light will turn on meanwhile green light and the pump will shut down. This indicates that the plant does not need the fertilization.
