In this paper, we present the design of a low-cost remote monitoring and control network for household cultivation, in which peripherals connected to each sensor-node can be re-configured remotely from the internet via a master node without any changing on the system firmware. The feasibility of the proposed scheme is evaluated via experiments. Particularly, the experiments set-up consists of one master node communicating wirelessly with some sensor nodes (slaves) to collect sensing data or send commands to them to manage the operating of the system. The sensing data from slaves will be collected and updated periodically to Google Sheets by master node via the internet connection. Additionally, slaves are equipped with versatile ports for connecting with sensors. The port is designed to be compatible with most popular communication standards such as analog, digital, I2C, UART, SPI. The key design of these communication ports is that when plugging/unplugging a sensor into/from a port, the corresponding slave can be re-configured directly on Google Sheets or keypad connected to master node. The research results can be further extended and improved to be applicable to household cultivation as well as application models of smart agriculture.
