TempTracker Frequently Asked Questions


BLE TempTracker

Is the product available to the market?

Chronicled is a blockchain and IoT technology company based in San Francisco. We are developing turnkey solutions enabling physical property to be securely linked to a blockchain for authentication, e-commerce, provenance, supply chain, and finance related use cases. Chronicled’s proprietary platform, comprising of hardware and software components, enables development of consumer and enterprise applications for physical goods, devices, machines, and product packaging.

What is the price of the product?

Our pricing is laddered based on volume and we expect to offer the TempTracker at approximate $10 at volume. We include the chip, form factor, text alert, and Blockchain data attestation service for a fixed one-time fee.

What is the accuracy of the BLE TempTracker?

We have multiple accuracy options for this sensor, in degree Celsius, these are the maximum errors:: +/- 0.1, 0.3, 0.4, 0.5, 1.0

Does the BLE TempTracker measure humidity as well?

Yes, a version of the TempTracker includes the humidity sensor.

Does your solution support any certification?

We are working on NIST and CFR 21 part 11 certification.

Can a client re-calibrate the TempLogger unit himself, or does he need to send to us to do re-calibration?

They are calibrated at the factory and they do not need calibration.

How many times can the BLE unit be re-used and re-calibrated?

It can be used until operational. [INTERNAL: We do not have yet information if the calibration is lost over time. Need to check with Silicon Labs

Is the battery on the BLE unit changeable?

No. The battery can be changed. However, we can build custom units with rechargeable battery.

Does your tracker come with other sensors?

We are developing a sensor with multiple sensors that we will launch in Q3. It will include movement, tilt, vibration, light and air measurements. The solution will be based on the same core components that we are using for the BLE TempTracker and target a low cost using high quality components. If you have a specific use case, we can work with you for a tailor version that can be delivered earlier than Q3.


NFC TempTracker

Is the product available to the market?

We will launch on May 1st with selected Chronicled customers and partners. If you are interested, we can provide you with a demo kit in early May. We are also accepting orders for our production batch. If you let us know the quantity that you need, we can verify with the manufacturing facility the fulfillment timeline, which is usually between 4 and 8 weeks.

What is the price of the product?

Our pricing is laddered based on volume and we expect to offer the TempTracker at approximate $5 at volume. We include the chip, form factor, text alert, and Blockchain data attestation service for a fixed one-time fee.

What is the accuracy of the NFC TempTracker?

The NFC Temp Tracker accuracy is 0.3 C absolute temperature between 0 C and 40 C, and 0.3 in the range 40 C and +85 C.

Is the NFC TempTracker reusable?

Although the NFC TempTracker was designed to be disposable (the battery cannot be replaced or recharged), it is possible to re-use it until the battery provides power to the sensor.

Can a client re-calibrate the TempLogger unit himself, or does he need to send to us to do re-calibration?

They are calibrated at the factory and they do not need calibration.


Cloud Service

Is your Cloud Service multi-tenant?

Yes, each organization has its own account and can register a team with personalized accounts.

Do you persistent the sensor data?

Yes, every time the App connects to the sensors, it uploads the data to the Cloud Service to make it available even if the sensor is not anymore available. Moreover, the data is synchronized with the blockchain to ensure attestation and persistence.

Do you support alert dispatching?

Yes, we provide an Text Alerts out of the box. Moreover, our API allows to integrate external systems to alert of anomalies in real-time, such as temperature out-of-bound and temperature returned to acceptable values.

Do you support white-labelling?

Yes, all your customers can be registered in our system as separate organizations with their own users.

Can we integrate your service with our existing systems/products/cloud services?

Yes, we support easy integration. We have a rich API to integrate it with third parties systems, including ERPs and other Supply Chain Solutions. See API at http://developer.chronicled.com.

What benefit does the blockchain bring?

We use the blockchain to securely store the data in an immutable ledger. Any change to the data is traced by the ledger. The solution is optimal to comply with regulations. When used with our cryptographic sensors, the solution provides end-to-end data provenance and attestation.
