摘要：
Smart farming is currently getting much attention from around the globe. There are a lot of works discussing on how to enable smart farm. One of the ways to make this happen is to have a smart controller that is durable, reliable, easy to use, IoT-enabled and cost-saving. This paper will describe the in-lab development smart greenhouse controller that responding to the aforementioned properties. The hardware of the propose prototype consist of power block, LCD, air temperature/humidity, soil moisture and 4 relays. All the components are embedded into a single Printed Circuit Board (PCB) that make a prototype consume low current around 223 mA or power consumption of 2.7 W. This device support three irrigation modes: scheduling, automatic and manual mode. Each mode can be configured by using UI in LCD that designed entirely to support local Khmer language. An IoT dashboard powered by Thingsboard is built to keep track the operation of the proposed prototype and is configured to communicate with the ESP32-based smart greenhouse controller via MQTT protocol. To demonstrate the performance, the proposed device is put to test in an actual greenhouse for a week and the result shows that the device can read the air temperature/humidity while control the valve and soil moisture correctly without showing any sign of error or bugging.
