Moisture notification system for the earthworm feeder cabinet

Abstract

Nowadays, Thailand is realizing the economic value of earthworms. Earthworm farming is a driving force that can stimulate the Thai economy. The objective of this project is to measure the humidity and temperature properties of the worms, the two boards are circuit boards in microcontroller. These are the WeMos D1 ESP8266 board and NodeMCU ESP-32S board. The WeMos D1 ESP8266 board to measure the amount of water and temperature of of the soil, and can turn the water supply on or off automatically. The NodeMCU ESP-32S board has a database system to collect real-time humidity and temperature data. The data is processed and displayed via a web interface. The experiment showed that in regard to earthworm farming, the soil moisture alert system in the earthworm closet has a temperature accuracy of 28.5°C. The top soil has a humidity accuracy of 65%, the middle soil has a humidity accuracy of 67%, and the lower soil has a humidity accuracy of 67%. This allows the ideal moisture and humidity levels for the propagation of earthworms to be maintained. The alert system displays the temperature and humidity in the earthworm closet and can turn the water supply off if the soil moisture level gets too high for the worms - this can all be monitored via the web application. .
