Tools for Detecting and Control of Hydroponic Nutrition Flows with Esp8266 Circuit Module

Abstract

In hydroponic plants, adequate nutrition and environmental temperature stability of nutrients are most important to maintain the fertility of the hydroponic plants. By monitoring nutrient flow and environmental temperature stability for hydroponics automatically, it will be easier for a farmer to monitor all of hydroponic plants. This paper, propose a tool for detecting and controlling the flow of food nutrients on the hydroponic plants using the ESP8266 circuit. First step, the sensor will detect the high nutrient solution and temperature around the hydroponic plants, then forward to microcontroller. By the microcontroller will be forwarded to the ESP8266 circuit module and send it to the Android Smartphone. The detection results of the proximity and temperature sensors that sent via ESP8266 will be used as parameters for flowing nutrients or not, and the parameters for turning on the cooling fan or not. The detection results of those sensors are sent to the smartphone by the ESP8266 circuit module, and then forwarded to the Android smartphone in real time. The data sent by ESP8266 module to thikspeak.com and android application has an average delay of 2.8 seconds on thinkspeak.com and 4.2 seconds on android application. This difference delay occurs because of the data entry is influenced of internet signals hotspots.
