‘AmbiTAG’: India’s First Indigenous Temperature Data Logger


  • A first-of-its-kind Internet of Things (IoT) device – AmbiTag has been developed by the researchers at the IIT Ropar Technology Innovation Hub - AWaDH and its startup ScratchNest.
  • The device records real-time ambient temperature during the transportation of perishable products, body organs, and blood, vaccines, etc. The AmbiTag temperature data log advises the user whether the transported item is usable or the cold chain has been compromised during the transportation.
  • It generates an alert when the temperature goes beyond a pre-set limit. The recorded data can be retrieved in user-defined format by connecting the USB with any computer.
