MEASURABLE OBJECTIVES
-
Sustainable Cooling Efficiency:
Reduce and maintain a difference between the internal and the room temperature of 15°C - 24°C using only water and passive evaporation only.
-
Autonomous Response Accuracy:
While ensuring when the internal temperature rises and exceeds the 26°C the NodeMCU is ready to activate the 12V exhaust fan with 100% reliability.
-
Cost Democratization:
With an overall production cost of not more than ₱5,000, the station will be 90% more affordable compared to the cheapest medical-grade refrigerators.
-
Data Integrity:
Have 100% data sync rate to the IoT Cloud and the LCD I2C display with a verifiable timestamped audit trail of every minute it is operating.
Innovative Cooling Solutions: From Idea to MVP Service
The Real-World Problem
The "last-mile" distribution of life-saving medical supplies such as vaccines and insulin is currently crippled by the electricity gap. Traditional refrigeration is far too costly and demands the presence of stable power grids - without which many regions are dubbed "rural" or merely "off-grid" - resulting in a global vaccination wastage rate of almost 50%. Existing low-cost alternatives such as the passive zeer pot do not have the active temperature controls and transparency of data that would guarantee the payload be kept safe and viable for human use.
Rural Health Workers:
Who need a self-monitoring storage solution for vaccines in the clinic still needs good storage that won't stop the vaccine from spoiling when power is cut off frequently.
Small-Scale Farmers:
Who need low-cost solutions for storing seeds and creating storage for fresh produce to prevent post-harvest losses, which will undermine their livelihoods.
Non-Governmental Organizations (NGOs):
Wanting to deploy low-cost and scalable infrastructure which can be deployed to disaster zones or to developing regions where the traditional logistics are no longer feasible.
WHY IT MATTERS:
A temperature breach is not simply a technical incident in the medical professions - it is also a life-threatening event. If a healthcare provider wasn't able to prove vaccine remained cold, that vaccine will have to be destroyed, effectively wasting precious value and communities at the same time.
