The Bluetooth Temperature and Humidity Logger TR32B is very simple to use; just insert a battery and place it where you want to measure and record temperature and humidity.

Its round design form with the sensor internalized is a departure from the “technical device” look and brings a comfortable familiar feeling that fits in with your decor. It runs on a single AA alkaline battery for about one year when using a recording interval of more than 10 seconds and collecting data once a day. It is compatible with smart devices and cloud computing, making it easy to manage temperature and humidity within everyday environments.


The Bluetooth feature of TR32B allows easy setup and data collection using the "T&D Thermo" application running on your mobile device.

The data retrieved by the mobile device can be viewed in a graph, saved, and uploaded to the cloud-based "T&D WebStorage Service" for anytime anywhere access.
