Abstract

Research on monitoring systems with control has been developed with several different inputs and outputs. This research has realized a smart greenhouse monitoring tool with temperature and soil moisture control on orchid plants based on the Internet of Things (IoT). This study aims to create a monitoring tool for temperature, air humidity, soil moisture, and water level. In the system, the microcontroller used is Wemos D1 R1, with inputs in the form of a DHT-11 sensor to measure air temperature and humidity, a soil moisture sensor to measure soil moisture, and an ultrasonic sensor to measure the water level in the containers. The resulting system output is in the form of pump and fan control. Based on the results of sensor testing, the accuracy of the DHT-11 sensor is 99.97%, the error is 0.03%, the soil moisture sensor is 98.63% accurate, the error is 1.37%, and the ultrasonic sensor is 97, 61% with an error of 2.89%. Based on the research results, the system can run well, as shown by Thingspeak, and the website smartgreenhouseanggrek.weebly.com can receive the results of monitoring sensor data using an internet connection. The tool will carry out the process of wateringplants when the soil moisture value read by the sensor is 20% and will stop watering when the sensor reads the soil moisture value reaches >= 50%. In contrast, the air temperature control is done by turning on the fan if the temperature reaches 30° C.

基于物联网(IoT)的兰科植物土壤温湿度控制智能温室监测

具有控制的监测系统的研究已经发展到具有几种不同的输入和输出。本研究实现了一种基于物联网的兰科植物温度和土壤湿度控制的智能温室监测工具。本研究旨在创建一个温度、空气湿度、土壤湿度和水位的监测工具。在该系统中，使用的微控制器是Wemos D1 R1，其输入形式为DHT-11传感器测量空气温度和湿度，土壤湿度传感器测量土壤湿度，超声波传感器测量容器中的水位。由此产生的系统输出以泵和风扇控制的形式出现。根据传感器测试结果，DHT-11传感器精度为99.97%，误差为0.03%，土壤湿度传感器精度为98.63%，误差为1.37%，超声波传感器精度为97.61%，误差为2.89%。根据研究结果，该系统运行良好，如Thingspeak所示，smartgreenhouseanggrek.weebly.com网站可以通过互联网连接接收监测传感器数据的结果。当传感器读取的土壤湿度值为20%时，工具将进行植物浇水过程，当传感器读取的土壤湿度值达到>= 50%时，工具将停止浇水。如果温度达到30℃，则通过打开风扇控制空气温度。
