Two-channel data logger BS-T2 WiFi is designed for continuous indoor operation. It is mounted on a wall. It is powered by an external 5V USB AC Adapter. It uses digital temperature sensors, external to the device, encapsulated in a metallic capsule, with the option of extending the cord to 30m.

The unit operates continuously in the presence of power. Every 8 seconds on a small, graphical display, 6 working screens are continuously exchanged with all the data necessary for monitoring. Above the display, two, two-color, sequential indicators, comfortable for remote viewing, are triggered when the customer's minimum and maximum temperature limits are interrupted separately for the first and second sensors. When crossing the set Upper limit, the device outputs a short alert tone with upward tones. When crossing the Lower Temperature Limit, the warning sound is downhill. The audible alarm can be turned off and only the light is left.

Measured and recorded data and settings in the BS-T2 WiFi recording thermometer are available through your mobile device or PC on the LAN. Data sent to our server is available from anywhere, at any time in graphical and tabular form. The server can send an email at any intersection of the customer's temperature limit. The email message contains the name of the device, the location of the installation location, the name of the owner company, the type of the alarm (upper or lower limit) and which sensor is generated - first or second, as well as the date, time and minute temperature graph of the activation.

Working with BS-T2 WiFi recording thermometer

BS-T2 WiFi connected to a wireless network
All data and settings are available with any web browser on a smart device - tablet, phone, laptop or desktop PC. The logger can connect to a local WiFi network with name and password setting or be accessed as a Web server if it is installed in a non-WiFi environment.

One of the flip screens shows the local IP address of the device, which the WiFi router automatically assigns to it after correctly entering a name and password.

If the measured temperature is higher than the set Upper limit,
the LED indicator lights up in RED.

If the measured temperature is lower than the Lower limit,
the LED indicator lights up in GREEN.
