A Solar-Powered IoT System to Monitor and Control Greenhouses-SPISMCG

Abstract

Agriculture benefits from technological advancements. Adopting technology in agriculture makes life easier and more secure for farmers. Growing vegetables in a greenhouse is a unique farm method. Greenhouses’ major goal is to create good growing conditions for crops while also safeguarding them from of the adverse weather and pests. The idea of this research is to integrate the Internet of Things (IoT) and solar power to monitor and regulate a greenhouse, allowing the farmer to maintain optimum environmental conditions within the greenhouse at any time. In this scenario, the photovoltaic module provides power to Arduino UNO, which is equipped with a LDR, a fire sensor, a temperature sensor, a soil moisture sensor, and a humidity sensor. These sensor readings are used to check day and night circumstances to turn on the light, detect smoke in the greenhouse, turn on the fan to reduce the excessive warmth, enable the water pump to maintain soil moisture level, and spray water to maintain optimal humidity, respectively. These data are sent to the farmer via the Node MCU Wi-Fi module, and these procedures can be automated or controlled using the Blynk app. The green house entrance system uses an RFID-enabled tag as an identifying badge to protect from unauthorized access. The use of photovoltaic modules in the implementation of this system can boost self-sufficiency and lower production costs.
