The wireless sensor device sends temperature data to Nexleaf servers and alert messages are sent to vaccine handlers and managers, if vaccine doses are in danger of spoiling. A weekly and monthly summary of refrigerators' temperatures is also sent via the website, so managers can understand how well equipment is functioning. Data analytics are available on the Nexleaf Dashboard to help understand managers where problems are arising in power supply, and how to resolve these challenges. Another example of these types of interventions is the SmartConnect project, which focused on developing a "communication appliance" to improve the reliability and performance of the “cold chain. The United States Agency for International Development (USAID) has supported and employed loT solutions via connected wearable technologies. Sensor Technology and Analytics to Monitor, Predict, and Protect Ebola Patients (or STAMP2 for short) has been tested on Ebola patients in the United States and is being scaled up to meet the needs of government agencies such as USAID for its Ebola treatment strategy in Liberia.
