dc.description.abstract | In recent years, the monitoring of hydroponics farms has undergone a significant transformation due to the
integration of sensors. However, the conventional method of manually observing measurements from multiple
sensors has proven to be excessively time-consuming and costly. Additionally, the lack of automatic data
recording options in most sensors has been a limiting factor. To address these challenges, we conducted an
experimental study to introduce a novel integrated sensor device named “HypoSense”, designed to monitor
essential parameters such as temperature, humidity, pH, light intensity, Total Dissolved Solids (TDS), and
Electrical Conductivity (EC) in hydroponic systems. HypoSense consists of three microcontroller units (MCUs)
incorporated with two controlling circuits based on the Arduino platform: the Arduino UNO, ESP32, and the
ESP8266 (NodeMCU) microcontrollers. The device is designed using high-precision sensors, including the
DHT11 for temperature and humidity monitoring, an Analog pH sensor kit for pH measurement, BH1750 for light
intensity, and an Analog TDS sensor kit for TDS and electrical conductivity measurements. These sensors were
chosen for their reliability, accuracy, and compatibility with the Arduino platform, ensuring that HypoSense
delivers precise and consistent readings. HypoSense is a cost-effective, portable sensor device specially designed
for monitoring growth parameters simultaneously in hydroponic farming, saving growers time and effort. The
evaluation was carried out in two phases. Firstly, field sensors were employed to calibrate HypoSense device
sensors. Next, a secondary evaluation was conducted to confirm the practicality and user-friendliness of the
HypoSense device. To facilitate the evaluation of HypoSense, we set up an indoor hydroponic system for growing
tomatoes and lettuce. The results of these evaluations, focusing on the performance and applicability of the
HypoSense device, will provide valuable insights for hydroponic growers and future researchers in precision
agriculture. | en_US |
