DTN1 Datasheet


The DTN1 Device is currently available in Engeneering Sample - Refer to the Roadmap for actual implementation status and limitations.


The DTN1 device is not delivered with a Final User System, targetted users are developers wishing to integrate the device in their ecosystem.

The DTN1 device is a temperature logging device with NDEF based NFC data formatting and long runtime of at least one year to support applications requiring long logging time and no maintenance activity.

Data logging can run both in a single pass mode, logging data then stopping once full, or in ring buffer mode where the oldest point are overwritten once the maximal number of points has been reached. The ring buffer mode enables applications requiring the temperature history of a certain time window before the readout time.

For applications requiring a yearly calibration, the long battery runtime allows users to start devices once then replace them with a newly calibrated one without intervention.
