3 . Chip overview 
GX20MH01 Digital thermometer provides temperature measurement at 14bit resolution with a lower temperature limit through a programmable non-volatile storage unit and upper limit alarm. 
GX20MH01 Use the single bus protocol to communicate with the upper computer, requiring only one signal line and one ground line. It has a temperature measurement range ranging from-55℃ to + 125℃. Test accuracy in the range of 0℃ to + 50℃ can reach ± 0.1℃. In addition, it can work in parasitic mode, directly powering the chip through signal lines, thus without requiring additional power supply. Each GX20MH01 has a globally unique 64-bit serial number, which can network multiple GX20MH01 in series on the same documentary bus, and requires only one processor to control multiple GX20MH01 distributed in a large area. This networking mode is especially suitable for HVAC environmental control, construction, equipment, food situation temperature measurement, industrial temperature measurement, process monitoring and control and other application fields.
