The measurement of body mass index (BMI) is an important indicator of preliminary assessment of human health. A higher BMI value increases the risk factor for critical diseases, e.g., high blood pressure (hypertension), cardiovascular disease, gallbladder disease, type 2 diabetes, etc. Obesity also increases the risk factor of COVID-19 in patients. BMI, the ratio of mass (in kilogram) to the square of height (in meter), is an estimation of an individual's physique. It depends upon the adult’s height and mass and is intended to evaluate the tissue mass. In this article, we have described the design and developmental aspects of a temperature-compensated BMI measuring system. The developed BMI measuring system is comprised of an ultrasonic sensor for height measurement, strain gauge-based load cell for precise and accurate mass measurement, a temperature sensor to eliminate the effect of temperature, and a microcontroller with related electronics, software, and display system. The developed BMI system is capable to measure mass precisely in the range (0–200) kg with a resolution of 0.01 kg, and height in the range of (0–4) m with resolution of 0.01 m. The expanded uncertainty in height measurement is estimated as 2.8 mm. The BMI value is determined with the help of these parameters and displayed with precision of 0.01. The novelty of the developed system is temperature compensation in the height measurement using an ultrasonic sensor, which has been introduced first time. Also, system is improved for its highly precise and accurate measurements at a comparatively lower cost than the commercially available existing systems.

温度补偿体重指数测量系统的设计与开发

体重指数(BMI)的测量是人类健康初步评估的重要指标。较高的BMI值会增加罹患严重疾病(例如高血压(高血压),心血管疾病,胆囊疾病,2型糖尿病等)的危险因素。肥胖也增加了患者COVID-19的危险因素。BMI(质量(公斤)与身高平方(米)的比)是对个人体格的估计。它取决于成年人的身高和体重,旨在评估组织的质量。在本文中,我们描述了温度补偿BMI测量系统的设计和开发方面。研发的BMI测量系统包括用于高度测量的超声波传感器,用于精确精确的质量测量的基于应变仪的称重传感器,用于消除温度影响的温度传感器,以及带有相关电子设备,软件和显示系统的微控制器。发达的BMI系统能够精确测量质量(0–200)kg,分辨率为0.01 kg,测量高度为(0–4)m,分辨率为0.01 m。高度测量中扩展的不确定度估计为2.8 mm。借助这些参数确定BMI值,并以0.01的精度显示。所开发系统的新颖之处在于首次使用超声波传感器进行高度测量时的温度补偿。而且,该系统以其高度精确和精确的测量得到了改进,而其成本却比市售的现有系统要低。以及带有相关电子设备,软件和显示系统的微控制器。发达的BMI系统能够精确测量质量(0–200)kg,分辨率为0.01 kg,测量高度为(0–4)m,分辨率为0.01 m。高度测量中扩展的不确定度估计为2.8 mm。借助这些参数确定BMI值,并以0.01的精度显示。所开发系统的新颖之处在于首次使用超声波传感器进行高度测量时的温度补偿。而且,该系统以其高度精确和精确的测量得到了改进,而其成本却比市售的现有系统要低。以及带有相关电子设备,软件和显示系统的微控制器。发达的BMI系统能够精确测量质量(0–200)kg,分辨率为0.01 kg,测量高度为(0–4)m,分辨率为0.01 m。高度测量中扩展的不确定度估计为2.8 mm。借助这些参数确定BMI值,并以0.01的精度显示。所开发系统的新颖之处在于首次使用超声波传感器进行高度测量时的温度补偿。而且,该系统以其高度精确和精确的测量得到了改进,而其成本却比市售的现有系统要低。发达的BMI系统能够精确测量质量(0–200)kg,分辨率为0.01 kg,测量高度为(0–4)m,分辨率为0.01 m。高度测量中扩展的不确定度估计为2.8 mm。借助这些参数确定BMI值,并以0.01的精度显示。所开发系统的新颖之处在于首次使用超声波传感器进行高度测量时的温度补偿。而且,该系统以其高度精确和精确的测量得到了改进,而其成本却比市售的现有系统要低。发达的BMI系统能够精确测量质量(0–200)kg,分辨率为0.01 kg,测量高度为(0–4)m,分辨率为0.01 m。高度测量中扩展的不确定度估计为2.8 mm。借助这些参数确定BMI值,并以0.01的精度显示。所开发系统的新颖之处在于首次使用超声波传感器进行高度测量时的温度补偿。而且,该系统以其高度精确和精确的测量得到了改进,而其成本却比市售的现有系统要低。借助这些参数确定BMI值,并以0.01的精度显示。所开发系统的新颖之处在于首次使用超声波传感器进行高度测量时的温度补偿。而且,该系统以其高度精确和精确的测量得到了改进,而其成本却比市售的现有系统要低。借助这些参数确定BMI值,并以0.01的精度显示。所开发系统的新颖之处在于首次使用超声波传感器进行高度测量时的温度补偿。而且,该系统以其高度精确和精确的测量得到了改进,而其成本却比市售的现有系统要低。
