Design And Implementation Of 02244 TDS Meter Gravity Sensor And 4502C pH Sensor On Hydroponic

Hydroponics is a method of sprouting plants in a nutrient solution without the use of sawdust, coir dust, coconut fiber etc. The technique has been followed in countries such as the United States. Hydroponic plants maintain adequate nutrition, ambient temperature and pH (hydrogen potential). The author uses 2 sensors, namely a gravity sensor tds meter and a pH sensor. On the pH and nutrient parameters to meet the accuracy of the stability of the water value, the controller will order to check the water value at intervals of 3 hours periodically. At an interval of 3 hours and the nutritional state is lacking, the water pump will pump nutrient water a and
$\mathbf{b}$
for 1 second and if the 3 hour interval the nutrients have not been fulfilled then the next 3 hour interval the pump will move one second. This mechanism will continue to repeat until the nutritional value is met as well as the pH sensor using an interval of 3 hours and using the same concept as the water nutrition mechanism.
