Abstract
Greenhouse technology is a solution to optimize food crop production. However, the controlled climate conditions in the greenhouse make extra work in monitoring and controlling environmental conditions in the greenhouse. This paper introduces a monitoring system for environmental conditions in a greenhouse using the internet of things (IoT) technology. Sensors are designed to collect information about environmental conditions in the greenhouse such as temperature, humidity, soil temperature, soil moisture, and light intensity. The data from the sensor is then sent to the gateway once every minute through an access point installed in the greenhouse area. Then the data received by the gateway is stored in the SQLite database. Besides, the data received by the gateway is also displayed in real-time through the Node-RED dashboard installed on the gateway as user interfaces for monitoring greenhouse conditions. The gateway installed in the greenhouse area is also connected to the local network server so that the monitoring of the greenhouse can be carried out over a larger area. The test results for seven days showed that the IoT prototype for the greenhouse monitoring system was able to run well. This is indicated by the average percentage of data that is successfully storing at 99.76% and the average percentage of data loss or duplication is 0.24%.
