Monitoring System Enlists High-Accuracy Temperature Sensor

For temperature-controlled shipments, modum.io AG has developed a compact data logger for temperature-controlled shipments that employs Sensirion’s STS3x high-accuracy, calibrated digital temperature sensor. As part of the monitoring solution for enabling EU GDP (Good Distribution Practice) compliance, it is capable of tracking environmental conditions for a variety of temperature-sensitive goods including pharmaceutical products.

 

Accuracy, compliance and auditability of the measurements are guaranteed by combining Sensirion’s calibrated temperature sensors with state-of-the-art blockchain technology. Upon receipt of a package, the receiver downloads the cryptographically signed measurement data from the temperature logger and the signed metadata such as the individual Sensirion serial number for end-to-end traceability. All data is wirelessly transmitted and checked by shipment-specific “smart contracts” on the blockchain, a decentralized digital ledger used to immutably store and verify its compliance with the conditions previously agreed to by the sender and receiver, allowing them to either release the product or arrange corrective or preventative actions.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

The STS3x sensors come in a 2.5 mm x 2.5 mm x 0.9 mm3 form factor with a supply voltage range of 2.15V to 5.5V. The sensors are fully calibrated, linearized and supply voltage-compensated, making a correction or calibration by the user unnecessary.
