GX18E20

Overview
The GX18E20 digital thermometer provides temperature measurement with a resolution of 12 bits, and can achieve lower and upper temperature limit alarms through programmable non-volatile storage units. GX18E20 uses a single bus protocol to communicate with the upper computer, requiring only one signal line and one ground line. Its temperature measurement range is -55 ℃~+125 ℃. The testing accuracy within the range of 0 ℃~+50 ℃ can reach ± 0.1 ℃. In addition, it can also operate in parasitic mode, directly supplying power to the chip through signal lines without the need for additional power supply. Each GX18E20 has a 64 bit serial number, which allows multiple GX18E20s to be connected in series on the same single bus for networking. With just one processor, multiple GX18E20s distributed over a large area can be controlled. This networking method is particularly suitable for HVAC environmental control, building, equipment, grain temperature measurement, industrial temperature measurement, and process monitoring and control applications.
