“Using the color of the desk lamp to show the growth rate of COVID-19 virus infections in a country or region, the display effect is more intuitive and not as stressful as chart data.”
Alex Newton released an IoT electrocardiogram monitoring (ECG) tutorial based on ESP32, demonstrating that remote cardiac monitoring can be carried out no matter how far the distance is between the doctor and the patient.
Alan Wang, a maker from Taiwan, used the MAX7219 LED module, the ESP8266-based D1 micro development board and MicroPython to develop a small tool that can update COVID-19 data in various countries in real time.
A distance monitor based on ESP8266 can remind people to maintain appropriate social distance at any time during the COVID-19 epidemic to prevent the spread of the virus.
This design is based on NUCLEO_F411RE as the control core, using the analog-to-digital converter inside the chip to collect external analog signals, and display the collected data with the cooperation of the TFT LCD screen. In order to facilitate visual analysis, the collected data is also drawn into a waveform graph. In order to verify its design function, a heart rate sensor is specially configured to obtain the heart rate signal. It has been actually verified that it can meet the basic requirements of the design during the acquisition process, and provides corresponding support for the generation of waveform image files. In addition, with the plug-in serial communication module, the collected data can be uploaded for deeper data analysis and processing.
Based on the blood pressure monitor design of MSP430F149, the project file may not be opened. Please create the project by yourself and add several other *.c *.h files at a time according to the file names contained in the main file. There may be some problems with the final result, but the basic idea is correct. If you modify it a little, you should get the correct result.
MAXREFDES104# is an evaluation and development platform designed specifically for wearable products and is used to demonstrate various health sign parameter detection solutions launched by Maxim. The third generation health sensor platform MAXREFDES101# health sensor platform version 2.0 upgrade system) integrates PPG + ECG into one analog front end (AFE) sensor MAX86176, body temperature sensor MAX30208, microcontroller MAX32666, power management IC MAX20360 and 3 axes Accelerometer. The complete development platform provides a 3D printed housing and a biometric algorithm concentrator with built-in heart rate, blood oxygen saturation and ECG algorithm MAX32670. Algorithm results can be output via Bluetooth®, or raw data can be transferred to PC GUI to facilitate system demonstration, evaluation and customized development.
The MAXREFDES1044 is a reference design for the MAX30101 and several other Maxim® products that demonstrates how a small size, low cost, low power, high accuracy heart-rate monitor can be easily implemented. This design can monitor heart rate using red, infrared (IR), or green LEDs.
In daily life, people often cannot stay away from the influence of radioactive radiation. For example, when they go to the hospital for a CT scan, professional practitioners in particular often need to effectively monitor the radiation dose rate in the environment. Nowadays, small personal dose values are commonly used. It is worn by individuals and the cumulative dose value within a period of time is calculated after regular submission. This project plans to design a model prototype of environmental dose monitoring equipment based on the GD32 domestic chip. It counts through Geiger tubes and uses digital tubes to display dose information in real time. When the dose rate reaches or exceeds the threshold, an audible and visual alarm will be generated. A GPRS module will be considered later. The data can then be uploaded to central management.
