Tools For Detecting and Control of Soil pH by Probe Sensor based on Android

Abstract

Soil pH is very vital for all life on agriculture. For a farmer, knowing how much of soil pH (Potential of Hydrogen) is very important. By detecting of the soil pH, it will be easier for a farmer to decide for certain agriculture plants. This research aims at develop an automatic soil pH detecting system for Farmer to visualize the soil pH demand of smart farmer using the microcontroller and smartphone. The tool model is as an information for the farmer, which also includes the devices of suitable plants on the soil which could be used to decide the type of plants suitable for the soil. By detection results of this pH sensor will decide also whether or not to drain nutrients and whether to flush the air conditioner or not. We developed the tools model to detect pH in some of soil. We include a Google maps also in order to find out the pH value of the soil in a particular region. We have tested a number of soil samples area, namely humus soil, soil with a mixture of manure, fertilizer, compost, and soil mixed with sand. The research shows the soil pH based on android by online. Furthermore, the pH value and address of the coordinates tested are stored in the firebase database. In detecting of soil pH, the system only need about 2-5 seconds time during the processing to detect the pH of some soil.
