Multiple Sensors System Design using Raspberry Pi for Monitoring the Greenhouse Environment

Abstract

    A multi-sensor system that uses wireless sensing is designed and implemented for monitoring many parameters of environment inside a greenhouse. In agricultural sector, sensors are used to collect air temperature, air humidity, soil moisture and intensity of sun light inside the greenhouse. The measurement results are sent to a Raspberry Pi which works like a coordinator in a wireless sensor network. The data collected from sensor node are stored in a local database and analyzed by the Raspberry Pi. It uses WiFi (IEEE 802.11g standard, operating at 2.4GHz) standard protocol to communicate with a router and uses wired connection to sensors. A website interface application is designed for experiments and showing the measured results on the greenhouse. The proposed system can be used to monitor multiple agricultural data on the greenhouse with highly exact results.
