WHAT IS IT?
  A complete IoT project you can run in Proteus: an ESP32 DevKit V1 reads three biomedical sensors and serves a live
  dashboard over Wi-Fi to a laptop and a phone, all inside one Proteus simulation.
    * AD8232 ECG module (ECGAD8232TEP): OUTPUT on D34, LO+ on D25, LO- on D26. The ESP32 samples the ECG 250 times
      a second, finds the beats (a light Pan-Tompkins detector) and shows the heart rate.
    * MAX30205 body temperature sensor (MAX30205TEP): I2C on D21 (SDA) / D22 (SCL), address 0x48, read once a second.
    * GSR skin response sensor (GSRGROVETEP): SIG on D35; skin conductance in uS and the count of skin responses.
    * D1 red LED (ALARM) on D18 and D2 green LED (NORMAL) on D19, each through a 220 ohm resistor.
    * Laptop WiFi Monitor (PC1) and Mobile WiFi Monitor (MOB1) open the dashboard at http://192.168.1.101/.
  The ESP32 joins the simulation's network TEP-WiFi (password 12345678) and gets 192.168.1.101. Its pages:
    /           the dashboard: status, links, heart rate, the ECG picture, temperature, skin conductance
    /ecg.bmp    the last 2.4 s of the ECG as a 300 x 60 picture, drawn by the ESP32 itself
    /data       all the readings as JSON (for a gateway or another program)
    /silence    stops the red LED blinking; it stays on while the alarm lasts
  Alarms: fever (38.0 C or more), heart rate under 50 or over 120 BPM, ECG leads off.
  The scenario is set in the sensors' properties: the ECG at 78 BPM with the electrodes off at 36 s for 2 s
  (LEADOFF=36), the body temperature 36.7 C rising to 38.6 C from 12 s to 20 s (BODY), skin responses at 8 s and
  20 s (EVENTS).

TEST STATUS
  Tested in Proteus 8 Professional on Windows 11, the run that made the tutorial's screenshots:
    * Wi-Fi joined in about 2 s of simulation time; the dashboard served to both monitors (HTTP 200).
    * Heart rate 77 - 80 BPM against the module's 78 BPM (it varies with the breathing).
    * Fever alarm at 20.37 s (the skin passes 38.0 C at 17.5 s; the sensor follows with a 2 s time constant);
      the red LED blinks, the green LED goes off.
    * Skin responses counted at 9.65 s and 21.57 s (the stimuli at 8 s and 20 s; the skin answers 1.5 s later).
    * Silence from the phone: the status says "(silenced)", the red LED stays on without blinking.
    * ECG leads off at 36.00 s and back on at 38.00 s; the new alarm blinks again.
  The ESP32 board runs at about half of real time on a typical PC, so 40 s of simulation take about 80 s.

INSTALLATION
  1. Close Proteus. Extract the WHOLE zip file, for example to your Desktop.
  2. Copy the files from "Proteus Library Files" into the LIBRARY folder of Proteus, for example
     C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\LIBRARY
  3. Copy the files from "Proteus Model Files" into the MODELS folder (next to LIBRARY).
  4. Start Proteus. Press P in the schematic and search for ESP32 DEVKIT V1, ECGAD8232TEP, MAX30205TEP or GSRGROVETEP
     to check that the parts are there.

RUN THE SIMULATION
  1. Open "Proteus Simulation\ESP32-Patient-Health-Monitor.pdsprj". Keep the .hex and .DLL files beside it.
  2. Press Play. The ESP32's serial monitor opens; after about 2 s of simulation it prints the dashboard address.
  3. Open the Laptop WiFi Monitor (PC1) or the Mobile WiFi Monitor (MOB1) and press Go: the dashboard and the ECG
     picture load. Press Refresh (or Reload) to update the page.
  4. Watch the alarms: the fever starts after 12 s, the electrodes come off at 36 s. Press Silence on the page to
     stop the blinking.
  5. Click a sensor during the simulation to open its pop-up (ECG trace, temperature, skin conductance).
  Your own sketch: the source is in "Arduino Code". Install the TEP Boards for Proteus add-on from the ESP32 DevKit V1
  post (it is in that post's download), choose Tools > Board > ESP32 DevKit V1 (TEP Proteus), export the compiled
  binary and set the board's PROGRAM property to the new .hex file. The same sketch runs on a real ESP32 Dev Module.

PROPERTIES USED IN THIS PROJECT
  U1 ESP32 DEVKIT V1  PROGRAM=ESP32_Patient_Monitor.hex
  U2 ECGAD8232TEP     BPM=78, RHYTHM=NORMAL, LEADOFF=36 (the LA electrode off at 36 s for 2 s)
  U3 MAX30205TEP      BODY=0:36.7, 12:36.7, 20:38.6, 40:38.6 (time in s : skin temperature in C),
                      WEAR=2 (the sensor goes on the skin at 2 s)
  U4 GSRGROVETEP      EVENTS=8:0.8, 20:1.2 (time in s : response in uS), WEAR=1 (fingers on at 1 s)
  PC1, MOB1           HOMEPAGE=http://192.168.1.101/

TROUBLESHOOTING
  * "Connecting to TEP-WiFi......" never ends: the board's PROGRAM file is missing, or TEPNET.DLL is not in MODELS
    and not beside the project. Copy the files again and restart Proteus.
  * The page says "Loading the picture..." for a while: the ECG picture comes after the page; wait a second, or
    press Refresh. The board is slower than real time.
  * Heart rate "measuring": the detector needs two beats; after the leads come back on it starts again.
  * A part is missing when the project opens: its LIB is not in the LIBRARY folder (step 2 of INSTALLATION).
  * Temperature reads low in the first seconds: the sensor warms up on the skin (WEAR), as a real one does.

LICENCES
  * The project, the sketch, the parts (LIB files) and the models (DLL files) are made by The Engineering Projects
    and are free for learning and for your own projects. The models use only standard Windows libraries.
    The C++ source code of the models is not included; the source code is not included for any model.
  * The .hex file is built from the sketch with TEP Boards for Proteus, the Arduino add-on in the ESP32 DevKit V1
    download; its licences are listed in that download.
  * Proteus is a product of Labcenter Electronics and is not included. ESP32, AD8232, MAX30205 and Grove are names
    of their owners; this project is not made or endorsed by them.
  * For learning only: a simulation, not a medical device.

VERSION
  V1.0 - the first release of the project.
