IoT monitoring simulation to predict CO2 tank depletion and prevent weekend gas outages in cell culture facilities. Monitors cylinder pressure, calculates consumption rates, and provides early warnings for timely replacement.
Monitor CO2 cylinder pressure and predict depletion times to prevent gas outages in cell culture incubators, particularly during weekends when laboratories are unmanned. Provides automated alerts and consumption tracking for proactive cylinder management.

Calculate remaining cylinder lifetime based on current pressure readings and historical consumption patterns.
from scripts.main import calculate_remaining_days, calculate_depletion_time
from datetime import datetime
# Current cylinder status
current_pressure = 8.0 # MPa
daily_consumption = 1.5 # MPa/day
# Calculate remaining time
remaining_days = calculate_remaining_days(current_pressure, daily_consumption)
print(f"Remaining days: {remaining_days:.1f}")
# Calculate depletion datetime
depletion_time = calculate_depletion_time(remaining_days)
print(f"Estimated depletion: {depletion_time.strftime('%Y-%m-%d %H:%M')}")
# Formula: remaining_days = pressure / daily_consumption
Parameters:
| Parameter | Type | Required | Description | Default |
|---|---|---|---|---|
pressure | float | Yes | Current cylinder pressure in MPa | 8.0 |
daily_consumption | float | Yes | Average daily consumption rate (MPa/day) | 1.5 |
capacity | int | No | Cylinder capacity in liters (10 or 40) | 40 |
Calculation Method:
remaining_days = current_pressure / daily_consumption
Best Practices:
Common Issues and Solutions:
Issue: Inaccurate consumption estimates
Issue: Pressure fluctuations causing false alerts
Identify if cylinder depletion will occur during weekends when laboratory staff is unavailable.
from scripts.main import is_weekend, will_deplete_on_weekend, calculate_depletion_time
from datetime import datetime
# Calculate depletion time
remaining_days = 3.5
depletion_time = calculate_depletion_time(remaining_days)
# Check if depletion is on weekend
if is_weekend(depletion_time):
print(f"⚠️ Warning: Depletion on {depletion_time.strftime('%A')}")
