Communication Protocol UART Communication Protocol 1. The protocol data are hexadecimal data. For example, “46” is [70] in decimal; [xx] is single byte data (unsigned, 0-255); (xx) is double byte, signed (-32768 to +32767), the high byte is in front of low byte. Behind “-” is remark. All data are integer, may there is (100,10,1) times corresponding relationship with the actual display data (sensor related). Baud Rate:9600, Data Bits: 8, Stop Bits: 1, Parity: No. Platform cannot send the data to PC automatically, module responses related data only after PC send command. The byte length of...

User Attention Please confirm before starting to test: (1) Sample gas needs to be pretreated to make sure that the sensor entrance is clean, no water and no oil. (2) Connect the sensor vent pipe with outside air to ensure the safety of emissions and ensure no blocking phenomenon. (3) Do not smoke or use open flame near the sensor. (4) The integrity of the pipeline must be ensured in use to avoid gas leakage caused by pipeline rupture. When the leaked gas contains poisonous and explosive gases, it may cause serious accidents. (5) When exhausting, please connect the exhaust pipe to the...
