this project is an attempt to modify the Digital Blood Pressure Monitor CH-605 of CITIZEN to send pressure measurements internet and to analyze their data in a better way.
I opened the device and I have met the following:
- Memory EEPROM AT24C08A http://www.atmel.com/images/doc5092.pdf
- LCD Display
- Two Button
- 1 Motor
- MCU unknown
I think the best option is to read the eeprom memory with the ESP8266 and send information via WiFi
