Design of monitoring and automation systems for greenhouse environment based on IoT

Abstract

In this paper, the greenhouse is controlled by a microcontroller module unit. Some sensors installed to detect soil moisture, temperature, and light intensity. The sensor measurement will be sent to the server via a microcontroller and displayed to web pages. It will control a pump, fan, and LED for adjusting the environment in the greenhouse. On the automatic controller, a pump installed for the moisture of soil, fan for temperature and humidity and LED growth if the lighting is lacking. The test from the sensors can run well, if the soil moisture below 40%, a pump will be automatic on. For temperature above 31°C, two fans will on. For light below 50%, LED will on. The system can control fans by dht11 temperature for 90%. The LDR can control LED for 85%. The soil moist can control a pump for 80%. The greenhouse can still run well in maintaining appropriate conditions on the plant. With the advancement of technology, we can control and monitor greenhouses using IoT.
