	Inside the TDA Dostmann CO² sensor, there's a CALIB interface, which consist of four PINs. GND and 5V can easily be determined using a multimeter with continuity test. These PINs are directly connected to the USB port and can be used to power our microcontroller. The other 2 PINs in the middle seem to send some data. After connecting them to a oscilloscope one PIN was obviously just clock, and the other data.		Inside the TDA Dostmann CO² sensor, there's a CALIB interface, which consist of four PINs.
