The BS-t2 WiFi dual-channel data logger is designed for continuous indoor use. Mounted on a wall. It is powered by an external 5V USB A network adapter. It uses digital temperature sensors, external to the device, encapsulated in a metal capsule, with the possibility of extending the cable up to 30 m.

The device operates continuously in the presence of power. Every 8 seconds on a small, graphic display, 6 working screens with all the necessary data for monitoring are gradually changed. Below the display, there are two, two-color LED indicators, convenient for remote monitoring. They are activated when the minimum and maximum temperature limits programmed by the customer are crossed, separately for the first and second sensors. When crossing the set Upper Limit, the device emits a short warning sound with rising tones. When crossing the Lower Temperature Limit, the warning sound is in descending tones. The audible alarm can be switched off and only the light can remain.

Measured and recorded data and settings in the BS-t2 WiFi recording thermometer are available through your mobile device or computer on the local network. The data sent to our server is available from anywhere and at any time in graphical and tabular form. The server can send an email at each crossing of the temperature limits programmed by the customer. The e-mail message contains the name of the device, the name of the place of installation, the name of the company-owner, the type of alarm (upper or lower limit) and from which sensor it is generated - first or second, as well as the temperature graph in date, time and minutes of activation.

The device can be used to inspect temperature processes with a clock rate of 1 to 5 seconds. The user does not need specialized software. When the BS-t2 WiFi is connected and powered by a USB cable to a computer, it is possible to receive a log file in tabular text format with just 4 simple commands. For communication they can use free programs for monitoring RS communication such as: PuTTY, CoolTerm and other.
