I'm working on iot based heart rate sensor how can I interface my heart rate sensor with wifi module(ESP 8266) and how is the code supposed to be ?
Please provide (a link to) the datasheet for the heart rate sensor.
did you try the sample code provided in the reference in post 3?
although it is for a UNO it will provide a starting point for the ESP8266
once you have the sensor data what do you want to do with it? e.g.run a webserver to display the data?
After collecting the data I want to display the data over a website or a mobile app.
Yeah I've tried the 3rd reference code but I am facing problem using the processing visualizer.
have a look at ESP8266 server sent events
the ESP8266 only supports WiFi - if you are thinking of Bluetooth Classic 2.0 or BLE move to an ESP32
upload your code using code tags </> and the output of the serial monitor as text
and a image of the "processing visualizer."
