This research is proposed the developing the system controls environment of earthworm that is controlled by smartphone. Because the original earthworm feeding is the watering prediction that sometimes the environment is unsuitable for earthworm feeding. The objective of the research is to design and develop an automatic watering system both automatic and manual. The watering system can be adjusted according to soil moisture for automatic controller. The system consists of hardware and mobile application. In case of hardware, the process is divided into three parts. Firstly, the nodeMCU ESP8266 receives the soil moisture and pH values that can be measured by the sensor. After that, these data are implemented according to the specified conditions to optimize the suitable soil moisture. Finally, nodeMCU ESP8266 control the operation of the relay to switch on and off the solenoid valve and pump. In terms of application, Blynk is mainly used to monitor the measured pH and moisture values in real-time. Moreover, user can select the function of operation system including automatic and manual modes. The system was implemented and tested in earthworm feeding farm at Yi-ngo District, Narathiwat Province, Thailand. The results showed the proposed earthworm feeding is better than the original feeding. The moisture of soil was maintained so that the average earthworm growth increased by 30 percent from the previous model, The production cost was reduced due to the use of water and rate of water use in the care was reduced by 70 percent from the previous model. The amount of fertilizer per production unit increased by 30 percent and system management is also easier.
