Tandd Bluetooth logger for temperature and humidity — Temperature and humidity monitoring with recorded data
This instrument fits facility teams, storage operators, laboratories, and compliance users that need a practical way to capture data during building a reliable record of environmental conditions for quality, traceability, and troubleshooting.
Compact Logger for Everyday and Facility Environments
The is an easy‑to‑use data logger that measures and records ambient temperature and humidity via Bluetooth. Just insert the included AA battery and position the logger where monitoring is required. Its clean, round design with an integrated sensor blends into offices, homes, and professional spaces alike, making it suitable for environmental monitoring in archives, exhibits, storage areas, laboratories, offices, and classrooms. Verified specs show it logs up to 8,000 paired temperature/humidity data points and supports recording intervals from 1 second to 60 minutes.
The Bluetooth connection works with the free “T&D Thermo” mobile app, letting you set up, view, and download data directly on a smartphone or tablet. Recorded data can be graphed, saved locally, and uploaded to the cloud‑based “T&D WebStorage Service” for access from anywhere with internet connectivity. Industry product listings confirm this logger’s simplicity and versatility for environmental tracking in homes, offices, storage facilities, and similar spaces.
How It Works
The TR32B uses Bluetooth Low Energy (BLE) to communicate with mobile devices. Data can be visualized in graph form in the app and sent to T&D’s WebStorage cloud service, where it is securely stored and accessible over the internet. Its long battery life—up to about one year under typical use—makes it reliable for ongoing environmental monitoring.

Technical Q&A
What measurement range does the TR32B support?
The logger measures temperatures from about 0 °C to 50 °C and humidity levels from about 10 % RH to 90 % RH, ideal for indoor environments and general monitoring.
How do I collect data from the TR32B?
Use the free “T&D Thermo” app on a compatible smartphone or tablet to connect via Bluetooth, view and graph recorded data, and upload to the cloud if needed.
Can I store data in the cloud?
Yes — data collected via the mobile app can be uploaded to the cloud‑based “T&D WebStorage Service,” allowing access from any internet‑connected device.
How long does the battery last?
With typical usage settings (e.g., 10 s recording interval with daily data collection), a single AA battery can power the device for about one year.
Is the device suitable for museum or archive monitoring?
Yes — its compact design and Bluetooth connectivity make it well suited for monitoring exhibits, archives, libraries, or any space where environmental conditions must be tracked over time.
Application Q&A
When is data logging especially valuable?
Logging is valuable when trends matter more than a single spot reading, such as curing history, storage conditions, verification records, or alarm-driven incident response.
Who is this best suited for?
Facility teams, storage operators, laboratories, and compliance users will get the most value when they need repeatable measurements plus a record they can review, export, or act on later.
Because it combines Low-energy Bluetooth, 8,000 data sets, Easy to install, this product is a strong fit for temperature and humidity monitoring with recorded data where documentation and repeatability are important.
