Low-cost Data Logger Development for Modern Agriculture การพัฒนาเครื่องบันทึกข้อมูลราคาประหยัดสำหรับการเกษตรสมัยใหม่

Abstract

Data loggers are really essential for modern agriculture, since agriculturists need to know environmental factors and variables, such as temperature, humidity and light intensity, for taking care of their plants. Because the data loggers available in the market are usually costly and inflexible to use, we proposed the development of low-cost data logger, which is suitable and sufficient for modern agriculture. The developed data logger consists of an SD card module, a real-time clock module, and a liquid-crystal display connected to an Arduino Due microcontroller board, which cost roughly 1,165 THB in total. In addition, firmware implementation and setting up for the data logger can be performed via Arduino IDE. The experimentation of the data logger incorporated with a digital temperature and humidity sensor, and an analog light intensity sensor to measure weather conditions on a farm land for 2 months showed that the developed data logger can be used to record the data every 5 minutes and store them into separate files for each day as designed. In addition, Arduino based data logger can be integrated with other environmental sensors such as rain detection sensors, water level sensors, and soil moisture sensors. This capability leads to additional applications including hazardous weather warning and automatic watering system.
