Goals

Maintain Pfizer vaccine temperature storage at -75 °C

Maintain solution temperature between 2 °C & 8 °C Continuous, 24/7/365 real-time monitoring, with historical data log

Immediate notifications and phone call alerts when temperature is outside threshold or when electricity is interrupted

Battery operation to allow continual monitoring even during power outages

Challenges

Operators manually check temperature and paper record keeping

No monitoring at night and weekends

Unscheduled electricity blackouts

Failure of auxiliary electric UPS backup system

Solutions

ControlbyWeb X-406: this Web-Enabled 1-Wire Multi-Bus Module has four 1-wire bus which makes the hardware wiring easier on the field. Up to 64 temperature/humidity sensors can be installed and connected to this device

ControlbyWeb X-KTC-B-24-72 K-type sensor: this calibrated K-type sensor has a sensing range from -200°C to 1000°C

ControlbyWeb X-TC1W-K Thermocouple to 1-Wire Adapter: this adapter is installed in between the X-406 and the K-type sensor

Results

Total visibility of vaccine and solution temperature storage

Avoid dramatic impact on vaccine viability and effectiveness

Data log to be used for accreditation audits and regulatory bodies

The Ministry of Health in Lebanon & UNICEF

Requested a monitoring alarm system to monitor the storage of the Pfizer vaccine at the central hub in Beirut which receives the Pfizer vaccine from overseas and distributes it to all hospitals in Lebanon. Haier Biomedical Freezers were used by the hospital to store the Pfizer vaccine at a temperature of  -75°C.

System requirements were as follows: 

  • Monitor the freezers storage and trigger an alarm when the temperature is outside the range of -65°C to -80°C
  • Send email notifications to specified email addresses
  • Make a phone call based on an escalation list (this service is not offered by ControlByWeb, but we used a third-party service)
  • Store the data for the past three months
  • Ability to graph the data in trends for data analysis
  • Ability to export the data
