1. General Information
1.1. General Description
The biosignalsplux Temperature (TMP) sensor is specifically developed for biosignal research
applications where it can be used to measure corporal or ambient temperatures. The sensor produces
an accurate analog output signal with short response times to temperature alterations.
The medical-grade PVC insulation of the Temperature sensor allows a safe use of this sensor even
when in direct skin contact. Additionally, the small form-factor of the sensor and small diameter of the
sensing element (~2mm) enable possibilities of local and accurate temperature measurements within
a 0°C and 50°C temperature range.
Figure 1: biosignalsplux TMP sensor
1.2. Typical Unfiltered Sensor Output
Figure 2 shows a typical unfiltered TMP sensor output. The raw digital sensor values received from the
biosignalsplux device ranged between 0 and 2n-1 (n=sampling resolution) were converted into the
original unit of measurement of this sensor (˚C) using the transfer function found in section Transfer
Function (Conversion Formula).

1.6. Transfer Function (Conversion Formula)
The analog sensor signals acquired with biosignalsplux devices are converted into digital values ranged
between 0 and 2n-1 (n=sampling resolution, usually 8-bit or 16-bit) and streamed in the raw digital
format.
In most applications, the original physical unit of the acquired TMP signal is preferred or required. The
raw digital sensor samples can be converted back into Celsius degrees (ºC) using the following
formulas:

2. Using the Temperature (TMP) Sensor with biosignalsplux &
OpenSignals
2.1. Connecting the sensor to biosignalsplux Systems
2.1.1. biosignalsplux 4-Channel Hubs
The biosignalsplux TMP sensor is compatible with all 4 analog input channels of the 4-channel
biosignalsplux hub, but incompatible with the reference/ground port. Connect the sensor to an analog
input to use it with this device.
Figure 4: TMP compatible biosignalsplux channels (green checkmarks).
2.1.2. biosignalsplux 8-Channel Hubs
The biosignalsplux TMP sensor is compatible with all 8 analog input channels of the 8-channel
biosignalsplux hub, but incompatible with the reference/ground and digital I/O ports. Connect the
sensor to an analog input to use it with this device.

2.1.3. biosignalsplux Solo & Single-Channel openBAN Devices
The biosignalsplux TMP sensor is compatible with the analog input channel of the biosignalsplux Solo
(openBAN) device. Connect the sensor to the analog input channel to use it with this device.
Figure 6: Connect the TMP to the analog input channel of the biosignalsplux Solo (openBAN).
2.2. Configuring the Sensor in OpenSignals
2.2.1. OpenSignals (r)evolution (Windows, macOS, Linux)
Note
Download OpenSignals (r)evolution here: https://biosignalsplux.com/index.php/software
Open the OpenSignals (r)evolution device manager to access and configure your biosignalsplux
device.

Select the device you intend to use for acquisition by clicking on ENABLE button on the device panel in
the OpenSignals device manager. The device is activated for acquisition if the ENABLE button is blue.
Figure 8: Enabling the device for acquisition.
Click on the biosignalsplux logo to access the available settings. Select the channel your sensor is
connected to and select the TEMP from the dropdown menu highlighted in the next screenshot.
Figure 9: Set the channel type of the channel you have your TMP sensor connected to TEMP.
Activate the channel for acquisition by clicking on the circle next to the channel type (must be blue). If
not done before, follow the instruction available in section 2.1 Connecting the sensor to biosignalsplux
Systems to learn how to connect your sensor to your biosignalsplux device. Click on the record button
in the OpenSignals main interface whenever you’re ready for your acquisition.
