TM is a cheap RS232 serial thermometer with measuring range from -55 °C to +80 °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).

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.
