Pengukuran Karakteristik Lahan Berbasis Internet of Things

Abstract

Climate change is one of the factors that affect crop production, so it is necessary to implement strategies and technologies to maintain the availability of cereal crops in Indonesia. It is necessary to prepare the land for the early planting process and monitoring plant growth in order to produce maximum crops. Utilization of the Internet of Things (IoT) can be used to monitor soil temperature and pH in real time, so hope for the long term it can increase crop production. The purpose of this research is to make a prototype design system with Internet of Things (IoT) technology to obtain temperature and pH data. This tool will test the functional accuracy. This research for measuring the characteristics of land based on IOT uses a prototype method consisting of Communication, Quick Plan, Modelling Quick Design, Construction of prototype, and Development Delivery & Feedback. Assembling the Wemos microcontroller, D1 R1, Breadboard, DS18B20 temperature sensor, 4700 Ohm Resistor, soil pH sensor, and 16x2 I2C LCD and connected using jumper cables with application control will be implemented into Wemos D1 R1 using the C++ programming language using Arduino IDE. Testing of the tool is carried out to ensure that the sensor is functionally able to read the temperature and pH of the soil correctly. Testing used black box method and was implemented in 5 land axis points at Politeknik Negeri Jember. The results used tools and litmus paper showed the same value. The conclusion and benefit of detecting land characteristics using the Wemos microcontroller showed more detailed measurement results with numbers behind the comma and a tool accuration rate of 100%.

Control system for temperature, humidity, and ammonia levels in laying hens farms based on internet of things

“…Internet of Things (IoT) is a technology that allows surrounding objects to be connected to the internet network [9]. IoT technology can be applied in the livestock sector to monitor temperature, humidity, and ammonia gas in laying hens.…”

“…allowing remote control of temperature and humidity [5][6] [9]. The temperature and humidity enclosure temperature in the range of 29-33,60 0 C and ammonia gas in the range of 0,36-197,56 ppm consistently, combined with the MQ135 sensor the resulting monitoring system [6].…”
