Control and Realtime Monitoring System for Mushroom Cultivation Fields based on WSN and IoT

Abstract

In this article, it is explained the design of control and monitoring systems for many mushrooms cultivation fields (kumbung) in realtime based on Wireless Sensor Network (WSN) and the Internet of Things (IoT). This system is designed to control and monitor temperature and humidity parameters in each kumbung. The system consists of several node boards in each kumbung and master board. The main components of the node board consist of Arduino Uno which is connected to XBee, DHT22 sensor, actuator in the form of a sprayer-pump, a blower and lamp. The main components of the Master board are Raspberry Pi and Xbee. Data is sent from each node to the Master using the WSN network with data packages that contain temperature and humidity data with the ID of each kumbung. The master board sends all kumbung data through a WiFi network to the Firebase realtime database that can be monitored via a smartphone. Kumbung control is performed by an actuator at each board node. The actuator keeps the temperature betwen 26-29°C and the humidity betwen 70-90%RH for mushrooms in the phase of body formation. The results of this system prototype experiment show that the functionality of the system is running well, although there is an average error 0,465°C for temperature readings and an average error 2,67% for humidity readings. This error is still in the DHT22 working area based on the datasheet.
