GX1831

Overview
The GX1831 digital thermometer provides temperature measurement with a 12 bit resolution and can achieve lower and upper temperature limit alarms through programmable non-volatile storage units. GX1831 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 -10 ℃ to+70 ℃ can reach ± 0.4 ℃. 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 GX1831 has a 64 bit serial number, which allows multiple GX1831s to be connected in series on the same single bus for networking. With just one processor, multiple GX1831s 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.
