Potential of hydrogen ion real-time monitoring

Abstract

Nowadays, the measurement technologies are continually growth in advanced. These can be seen in the developed and developing countries that research and develop the products, which support the consumer behavior and/or country economy ic growth. However, some advanced products are very expensive such as pH meter. Therefore, this thesis develops the pH meter, which allows the acid-base test of the water and it can be supported the agriculture. The proposed pH meter is included the pH pen sensor, temperature sensor, water level sensor. The proposed meter can measure the acid-base of the water by sending SMS alert signal via GSM module to the mobile phone of the farmer. As can be seen, this thesis can prevent and solve the effect of the high acid-base of the water that possibly flows into the agriculture farm via using SMS alert signal of the mobile phone of the farmer.
