Microproject "Intelligent Greenhouse" in - Cisco Packet Tracer 8.2.2
Topic: construction and modeling of a "smart" greenhouse in Cisco Packet Tracer 8.2.2.
Goal: to automatically maintain comfortable conditions for growing (using cherry tomatoes as an example) — temperature, humidity, water level, lighting — and send notifications about any changes.
Initial Assumptions
| Parameter | Normal Range | Critical Thresholds |
|---|---|---|
| Soil/Air Temperature | 20 – 30 °C | < 20 °C or > 30 °C |
| Air Humidity | 40 – 70 % | < 40 % or > 70 % |
| Water Level in Tank | 20 – 80 % | < 20 % or > 80 % |
| Lighting | on 18:00-06:00 | off during the day |
Physical (IoT) Devices
| Name (Display Name) | Type | Function |
|---|---|---|
| IoT4 Door | Door | Motorized opening/closing (start — closed) |
| IoT13 RFID Reader | Reader | Card access (ID = 1001) |
| IoT1 Light | Lamp | Additional light at night |
| IoT3 Fan | Fan | Cooling, air circulation |
| IoT10 Furnace | Heater | Heating at < 20 °C |
| IoT2 Lawn Sprinkler | Sprinkler | Watering at low humidity |
| IoT5 Water Drain | Drainage | Discharge of excess water |
| IoT6 Water Level Monitor | Water level sensor | 0 – 100 % |
| IoT11 Humidity Monitor | Humidity sensor | 0 – 100 % |
| IoT8 Thermostat | Thermostat | Temperature °C |
| IoT9 Smoke Detector | Smoke detector | Alarm on smoke |
| IoT0 Window | Window | Automatic ventilation |
Done
Topology — Home Gateway, Switch, Server-PT (SMTP), SBC-PT, Laptop and Smartphone.
All IoT devices added (sensors, fan, lamp, window, door + RFID).
Wi-Fi configured (SSID HomeGateway), DHCP, mail server and two e-mail accounts.
Python script on SBC-PT: response to temperature, humidity, water level, smoke; night lighting; door opening with card; e-mail notifications.
Not Working
Door (IoT4) and RFID reader (IoT13) do not accept commands from the script → do not open/close.
e-mail alerts are not sent, and full tests do not pass.
