Abstract

In this paper, we present a multi-range of ammonia gas concentration control and monitoring via IoT system. We can select the ammonia gas concentration measurement range by adjusting load resistance within the voltage divider circuit. The appropriate measurement range, which corresponds to the concentration of ammonia gas produced by agricultural and industrial activities, can control and monitor via Blynk application. The MQ-137 gas sensor is selected as the main sensor, and each load resistance condition within the voltage divider circuit is calibrated with known ammonia gas concentration inside a calibration box. The calibration data is input into computer programming and processed by ESP8266 microprocessor. After calibration, we obtained a multi-range ammonia gas sensor suitable for measuring the ammonia gas concentration for each concentration range. The experiment showed that load resistance affects the measurement accuracy of ammonia gas concentration. We can select the load resistance suitable for the ammonia gas concentration and display on a smartphone via IoT system.

通过物联网系统的多范围氨气传感器控制和监测

在本文中，我们提出了一种基于物联网系统的多范围氨气浓度控制和监测。通过调整分压器电路内的负载电阻，可以选择氨气浓度测量范围。通过Blynk应用程序可以控制和监测与农业和工业活动产生的氨气浓度相对应的适当测量范围。选择MQ-137气体传感器作为主传感器，在一个校准盒内用已知的氨气浓度对分压器电路内的各个负载电阻情况进行校准。标定数据输入计算机编程，由ESP8266微处理器处理。经过标定，我们得到了一个多量程氨气传感器，适用于测量每个浓度范围的氨气浓度。实验表明，负载电阻影响氨气浓度的测量精度。我们可以通过物联网系统选择适合氨气浓度的负载电阻，并在智能手机上显示。
