WHAT IS IT?
  A small greenhouse you can run in Proteus: a Raspberry Pi 5 waters the plants when the soil dries, cools the air
  when it gets hot or humid, switches a grow lamp on in the dark, guards the water reservoir and shows it all on a
  web page.
    * DHT22 temperature and humidity sensor (DHT22ADVTEP, DHT1) on the Pi's 3V3: DATA on GPIO4.
    * ADS1115 16-bit ADC (ADS1115ADVTEP, U1) on +3.3V, I2C1 (SDA GPIO2, SCL GPIO3), ADDR on GND = address 0x48:
      A0 the soil, A1 the light, A2 the water level.
    * Soil moisture sensor (SOILADVTEP, U2) on +3.3V: A0 to the ADS1115's A0. MOISTURE=45 at the start.
    * LDR light sensor (LDRADVTEP, U3) on +3.3V: A0 to the ADS1115's A1.
    * Water level sensor (WATERLEVELADVTEP, U4) on +3.3V in the reservoir: S to the ADS1115's A2.
    * L9110S motor driver (L9110SADVTEP, DRV1) on 12 V: A-IA on GPIO17, A-IB on GPIO27; A-OA / A-OB to the pump.
    * 12 V peristaltic pump (PERIPUMPTEP, M1): 4-second doses, a 10-second soak between them.
    * 4-pin PC fan (PCFAN4PINTEP, FAN1) on 12 V: PWM on GPIO18 (LOW = its minimum, HIGH = full speed), TACH on
      GPIO23 (the Pi's pull-up; two pulses a turn).
    * 1-channel relay module (RELAY1ADVTEP, RLY1) on 5 V: IN on GPIO22 (active LOW); COM on 12 V, NO to the lamp.
    * 12 V lamp (BULBW5WTEP, L1): the grow lamp.
    * RASPBERRY PI 5 (PI1) runs greenhouse.py on Ethernet at 192.168.1.51; the dashboard is on port 8000.
    * Laptop WiFi Monitor (PC1) and Mobile WiFi Monitor (MOB1) open http://192.168.1.51:8000/.
  The rules (at the top of greenhouse.py):
    * the soil below 35 %: a dose, a soak, again until the soil reaches 45 %;
    * the reservoir below 25 %: watering blocked (the pump never runs dry);
    * above 30 C or 85 %RH: the fan at full speed; below 28 C and 75 %RH: back to its minimum;
    * the light below 25 %: the grow lamp on; above 40 %: off.
  Its pages:
    /            the dashboard: the air, the soil, the light, the reservoir, the pump, the fan, the lamp, the events
    /water       one dose of water now (refused when the reservoir is low)
    /fan         the fan by hand (full / minimum)
    /lamp        the lamp by hand (on / off)
    /auto        the fan and the lamp back to AUTO
    /data        everything as JSON

TEST STATUS
  Tested in Proteus 8 Professional on Windows 11, the run that made the tutorial's screenshots (simulation times):
    * Start: 24.0 C, 50 %RH, the soil 45 % (A0 2.045 V), the light 87 %, the reservoir 50 % (AIN2 1.6818 V).
    * Dry 10 on the soil: "the soil is dry (10 %) - watering" and "pump ON: dose 1 (4 s)" at 12.0 s (80.1 mL/min,
      100 RPM, 11.50 V, 252 mA); "pump OFF - soaking for 10 s" at 16.0 s; dose 2 at 26.0 s (the soil at 30 %);
      "the soil is moist again (50 %) - watering done after 2 doses" at 40.0 s (Water the plant after each dose).
    * HOT on the DHT22: "fan FULL (AUTO: 38.0 C, 30 %RH)" at 44.0 s, 1440 - 1470 RPM (tach 48 Hz); ROOM: "fan
      minimum" at 52.0 s, back to 300 RPM.
    * Night on the LDR: "grow lamp ON (AUTO: light 7 %)" at 53.0 s (relay coil 69.3 mA, the lamp 416 mA); Indoor:
      "grow lamp off" at 57.0 s.
    * Empty on the water sensor: "the reservoir is LOW (8 %)" at 59.0 s; WATER on the laptop: "no dose: the
      reservoir is low (0 %)" at 61.0 s; Full 40: "the reservoir refilled (26 %)" at 63.0 s.
  66 s of simulation took about 14 minutes on our PC with all the captures.

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 everything in "Proteus Model Files" - the DLL files AND the TEPPi folder - into the MODELS folder
     (next to LIBRARY). TEPPi holds the Python 3.11 that the Raspberry Pi board runs and our TEP Pi runtime.
  4. Start Proteus. Press P in the schematic and search for RASPBERRY PI 5, DHT22ADVTEP or PERIPUMPTEP to check that
     the parts are there.

RUN THE SIMULATION
  1. Open "Proteus Simulation\Pi-5-Smart-Greenhouse.pdsprj". Keep greenhouse.py and the DLL files beside it.
  2. Press Play. The Pi's terminal prints a status line every 5 seconds.
  3. Open the Laptop WiFi Monitor (PC1) or the Mobile WiFi Monitor (MOB1) and press Go. Press Refresh to update it.
  4. In the soil sensor's pop-up (U2) press Dry 10: the pump gives a dose. Press Water the plant after each dose
     (+20 %) to see the soil respond; at 45 % the watering stops.
  5. HOT on the DHT22's pop-up (DHT1): the fan at full speed. Night on the LDR's pop-up (U3): the grow lamp on.
     Empty on the water sensor's pop-up (U4): the reservoir LOW, watering blocked; Full 40 refills it.
  Your own program: edit greenhouse.py beside the project (the thresholds at the top) and press Play.

TROUBLESHOOTING
  * The terminal cannot start Python: the TEPPi folder is not in MODELS (step 3 of INSTALLATION), or an older one.
  * The air shows "no reading yet": the DHT22's DATA is not on GPIO4, or it has no supply.
  * The soil, light and reservoir all read 0 %: the ADS1115 is not at 0x48 (ADDR on GND), or SDA / SCL are swapped.
  * The pump never runs: the reservoir is low (refill it in U4's pop-up), or the L9110S has no 12 V.
  * The fan never goes to full speed: its PWM wire is not on GPIO18.
  * The lamp is on when it should be off: the relay's IN is active LOW - a HIGH GPIO22 keeps it off.

LICENCES
  * The project, the program, 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.

    holds our TEP Pi runtime with gpiozero and colorzero (BSD licences) - their licence files are inside the folders.
  * Proteus is a product of Labcenter Electronics and is not included. Raspberry Pi is a trademark of Raspberry Pi
    Ltd; DHT22 (Aosong), ADS1115 (Texas Instruments) and L9110S are names of their makers. This project is
