Abstract

This research focuses on designing and assembling a compost production system using cow manure and asparagus plants as raw materials. This system is controlled by the Internet of Things to reduce the cost of purchasing organic and chemical fertilizers, increase the fertility of nutrients in the soil, and reduce toxic air pollution caused by burning asparagus trees.  The process uses three compost piles. The first one uses the technique of scheduling watering inside the fertilizer pile. The second one uses watering techniques in piles based on the set fertilizer moisture, and the third pile uses Maejo engineering techniques number one.  This study includes designing and assembling compost pile control, then designing and programming an Arduino IDE to contact MCU ESP8266. The network side uses Netpie 2020 as a controller and display.  This research adopted Node-Red as a gateway to support the future use of InfluxDB and Grafana. To maintain system stability, a backup was made in case of a cloud server failure of Netpie 2020 using MySQL, creating a database to store data from the sensor into the server, and using Line notify to report the operating conditions of the system. The fertilizer composted over a period of 60 days was taken to measure the amount of minerals and nutrients, the nitrogen and phosphorus elements of all three stacks were similar which is greater than the standard level of organic fertilizer (grade A). However, the potassium level is substandard.  The payback period for setting us such a control system is only 2 years.
