    TM is an RS232 serial thermometer with measuring range from -55 °C to +125°C. It communicates in a simple ASCII format.

    Digital sensor TM can very easily measure temperatures and transmit those measured-out values to a PC. As a transfer protocol TM uses a simple ASCII format so there is no conversion needed (Output directly in degrees celsius °C). It is connectrd to the PC via a COM port (RS232).

    Features of simple serial thermometer

    • Measures temperatures from -55°C to +125°C, 0,1°C resolution
    • Output is in ASCII format in °C, no conversion needed.
    • Connects to a serial port (COM)
    • Port powered
    • Wix software included (freeware)
    • Easily integrated in own applications (DLLs, souce codes and communication description provided freely)


    • Temperature meaurement for living areas, warehouses and manufacturing areas.
    • Outside temperature measuring (waterproof sensors available on request)
    • Local area information on your WEB site - internet thermometer
    • Sensor cable length
    • Standard cable length is 3m. Other lengths available on request. Maximum cable length is 20m

    Don't have serial port on your PC? Try our USB thermometer. Looking for Ethernet thermometer? If you need to measure several distant locations, you can use similar sensors called TQS3.

    Connection of RS232 thermometer
    TM Thermometer is to be connected to your PS's COM port (Serial port). Sensor is to be located in the area you need to measure.

    Thermometer function description
    TNM is connected and powered from a serial port (COM). Once the DTR signal is activated, TM measures temperature and sends it to the PC in ASCII format as a string. When DTR is active continuously, TM sends the current temperature every 10s. This is indicated by an LED on the RS232 connector. Standard sensor is fo atmospheric measurements only.

    Connections.  TM only has on serial connector (CANON9, DSub9) that is to be connected directly to a PC.
    • pin RS232 signal
    • 2 RXD Recieves data from the sensor - measured temperature
    • 4 DTR Powers and controls the sensor
    • 5 GND Signal grounding
    • Thermometer communication protocol
    • TM can be easily used with a supplied software (WIX), custom software or any terminal (TeraTerm, Telix, hyperterminal). Customer made softweare is another option as the communication protocol is very simple.
