Manufacturing an IoT device for automatic control of total disolved solids of nutritient concentration for plants on aeroponic, hydroponic systems
Tóm tắt
Controlling TDS (Total Dissolved Solids) in aeroponic and hydroponic systems is very important for plant growth. Due to the reflux of the nutrient solution after passing through the tube system containing the medium, the concentration of nutrients decreases. Currently, measuring nutrient concentration and adding nutrients to the solution is manually done by farmers. Therefore, we manufactured an IoT (Internet of Things) device with acceptable accuracy to control nutrient concentration. In testing, the TDS sensor has a relative errror of ~ 1.2 %. The IoT device can automatically turn on the pump to provide more nutrients when its TDS is below the TDS threshold and turn off the pump when the concentration has reached the threshold. With our system, users can directly enter the TDS threshold using the matrix keypad or via the Blynk smartphone application.
