Wearable IoT Well being Monitoring System

The wearable AC cum Heater was already printed in EFY.  Within the wearable AC cum heater, the fan will rotate and funky the physique primarily based on the temperature and vice versa. 

We proposed among the extra options for this product that are mentioned beneath.

On this challenge, we moreover proposed a transportable well being monitoring gadget utilizing a Coronary heart charge and temperature sensor. The info might be despatched to the ThingSpeak cloud utilizing ESP8266 Node MCU. On this challenge, we now have used the ESP8266 NODE MCU, Temperature sensor, Coronary heart charge sensor, and OLED show. This proposed on-line well being monitoring system is used to measure physique temperature and pulse charge with none human intervention, and the information is distributed to the cloud and cellular widget for physician’s prognosis functions. It’s useful through the Covid pandemic scenario. An IoT know-how has been used on this challenge for sharing the affected person temperature and coronary heart charge information to the physician’s cell phone for taking speedy care. These information are saved within the cloud and it may be used as a knowledge set. In future, by utilizing this information set the cardiovascular danger may be predicted by utilizing the machine studying algorithm

Elements Used:

• ESP 8266 NODE MCU
• Temperature Sensor (LM23)
• Coronary heart charge Sensor (KY039)
• OLED Show (128×64)

Circuit Diagram:

Design Process:

1. The sensor pins are related to the corresponding pins of ESP8266 NODE MCU as per the circit diagram.
2. USB mini adapter cable used to energy up the ESP8266 Module.
3. Create the channel within the ThingSpeak app and channel API key copied in this system.
4. Set WiFi connection to the NODE MCU sort SSID and Password in this system.
5. The analog voltage obtained from the temperature sensor and transformed into temperature in diploma Celsius by utilizing the ADC with the next conversion formulation.

LM35_TempC_Sensor1 = Voltage / 10;

LM35_TempF_Sensor1 = (LM35_TempC_Sensor1 * 1.8) + 32;

1. Equally the digital coronary heart charge worth obtained from the heartbeat sensor.
2. Each the values ship to OLED show by means of SDL and SCL pins.
3. Additionally the measures values ship to Thingspeak cloud.
