AUTOMATIC GREEN OAK FARM
This research is about an automatic hydroponic lettuce cultivation management system developed from "ESP32" sending communication MQTT to the cloud server, which includes pH "PID control", fertilizer concentration "PID control", water temperature "on/off control", and electricity usage measurement. I grow green oak lettuce.
FEATURE
- Control pH value with "PID control"
- Control fertilizer concentration with "PID control"
- Control water temperature with "ON/OFF control"
- Measure the electricity used
- Use online on node-red dashboard
- Store data in database influxdb
- View parameters in the past on grafana
Installation
It is installed in a space where the plants can receive adequate sunlight and have proper air circulation.
Benefits received
By eliminating issues related to inconsistent nutrients and water quality, the plants receive adequate nourishment and can grow to their full potential, resulting in heavier yields. However, there is still a lack of consistency in production because the system does not control the climate.
