Closed Smart Vegetable Growing Cabinet System

This project aims to build a smart closed vegetable growing cabinet to reduce the risk of harmful vegetables and to incorporate the intelligent vegetable growing cabinet's fertilizer mixing control system for temperature and humidity control fertilizer dispensing system. The entire device design was consistent with the width of the vegetable growing cabinet of 60 cm., width 120 cm., height 127 cm. and can grow 15 installed plants. Sensors for temperature and humidity inside the cabinet, the temperature control setting does not exceed 35 degrees Celsius, nor does the humidity exceed 90%. The ventilation fan will operate to decrease the temperature and humidity to the acceptable level until surpassed. For fertilization, the EC PH sensor was mounted, and the EC was set at 1.0-1.8 μS and the PH value is 5.00-7.00. In addition, a clock module has been mounted for use in setting time to turn the LED lamp on-off for vegetable growing. The NB-IoT data transmission system installed to send notification information to the Line application at a given time also has a system installed that can add water automatically. Easily add water to the smart vegetable growing tank by using a contactless water level sensor.
