摘要

温度是许多工业和商业应用中最受监控的项目之一。物联网(IoT)温度传感器通常体积小，功耗低，并且能够测量湿度。在物联网系统中，获取及时、准确的温度信息至关重要。本文旨在通过将物联网温度系统与工业系统进行比较来评估物联网温度系统的性能。在本项目中，使用DHT22温度传感器和树莓派开发了一个物联网温度监测系统来代表物联网温度监测系统。通过将其温度测量与连接到Keithley 2110台式数字万用表的Keithley 6517-TP工业级温度探头作为采集系统进行比较，对系统进行了评估。利用DHT22传感器的物联网温度监测系统可提供高达0.10℃的精确测量，但在检测温度变化时响应较慢。这一发现将能够为开发需要温度监测的物联网系统提供参考。

On the Evaluation of DHT22 Temperature Sensor for IoT Application

Temperature is one of the most monitored items in many industrial and commercial applications. Internet of Things (IoT) temperature sensors are commonly small, low power, and able to measure humidity as well. Obtaining timely, accurate temperature information is critical in an IoT system. This paper aims to evaluate an IoT temperature system’s performance by comparing it with an industrial system. In this project, an IoT temperature monitoring system has been developed using a DHT22 temperature sensor and a Raspberry Pi to represent an IoT temperature monitoring system. The system is evaluated by comparing its temperature measurement with a Keithley 6517-TP industrial grade temperature probe connected to Keithley 2110 benchtop digital multimeter as the acquisition system. The IoT temperature monitoring system utilizing the DHT22 sensor provides accurate measurement up to 0.10C but a slower response in detecting temperature change. This finding would be able to provide a reference in developing an IoT system that requires temperature monitoring.
