Abstract

Abstract

The objectives of this research were to study the development of a prototype the proximal sensing system and to develop a sensor web system of water quality data for water body of the Natanakarn garden, Burapha university. The Arduino board using control of the water measurement system and 3G wireless signal a transmission spread from the temperature and pH sensor of the Natanakarn garden, Burapha university Chon Buri province. For real-time storage in Thingspeak system and display on the website. Result of validation temperature sensor measured of first sensor values is 37.54 degree Celsius and compared to the Thermometer is 37.55 degree Celsius and the pH sensor is approximate to the pH meter at about 7.15. The temperature sensor measured of second sensor values is 37.78 degree Celsius values is equal to the Thermometer. The pH sensor is approximate to the pH meter at about 7.151 -7.52 and the temperature sensor measured of third sensor values is 37.78 degree Celsius compared to the Thermometer is 38.69 degree Celsius. The pH sensor is approximate to the pH meter at about 7.39-7.40, which determine the accuracy of the sensor criteria for good and data stored in ThingSpeak by create channel API for received values from water quality measure sensor of 3 sensors. Sensor and ThingSpeak system connected HTTP type. Tranmittion data values every 1 minute and Display graph in the format. The Interpolation analysis using IDW method of Geoinfomatics with water quality measurement values exported Comma-separated values (.CSV) format from ThingSpeak system for put into interpolation of temperature and pH values for intepolation mapping and publish on website.
