Environment Dynamic Monitoring and Remote Control of Greenhouse with ESP8266 NodeMCU

Aiming to reduce the labour cost in managing greenhouses, an combined green-house management system including environmentally dynamic monitoring system and remote control system were developed and implemented in a greenhouse. The central unit of this combined system is the ESP8266 NodeMCU board. Environmental parameters including air temperature, air humidity, CO2 concentration and soil moisture were selected to represent the state of the interior environment state of the greenhouse. Based on HTTP protocol, the ESP8266 NodeMCU connected to the Wi-Fi and communicated with IoT platforms, Thingspeak and Bylnk. The data regarding environmental parameters was collected from sensors was processed and sent to cloud and IoT platforms though Wi-Fi. Environmental data was visualized in time-series form on IoT platforms allowing users to know about the internal environment conditions in real time. Moreover, the remote system has enabled users to change the operative condition of environment controllers remotely by altering between the on-off state of control buttons on Bylnk android application. This combined system has low-cost characteristics and is suitable for indoor garden, sized greenhouse. Moreover, it can be applied in modern smart agriculture.
