Explanation:

• The Indian Institute of Technology Ropar, in Punjab, has developed a first-of-its-kind Internet of Things (IoT) device named ‘AmbiTag’ which can record real-time ambient temperature during the transportation of perishable products such as vaccines, body organs and blood.
• AmbiTag is a USB-shaped device, capable of continuously recording the temperature, ranging from -40  to 80, of its immediate surroundings in any time zone for a full 90 days on a single charge.
• This is in contrast to most of the similar devices in the international market which can record data only for a duration of 30 – 60 days. 
• AmbiTag will generate an alert when the temperature goes beyond a pre-set limit.
