Optical sensor series 4 symmetrically distributed air holes Interface lead definition Pin number Table2 Sensor interface lead definition Operating Instructions： To ensure the normal operation of the sensor, the operating voltage of the sensor must be within the range of 3.3V-5.0VDC. If the voltage exceeds this range, a fault may occur, or the sensor may not work properly. To ensure the normal operation of the sensor, the current output capacity of the power supply should be no less than 500mA. If the power supply circuit capacity is lower than this value, the fault may occur, or the sensor cannot...

Optical sensor series Communication Protocol 1)communication setting Baud rate Table3 Sensor communication setting 2)Communication format When the probe is in the detection state, the output form is ACSII string fixed-length output, a total of 29 bytes, the format is as follows: symbol xxx.xx space symbol nn.n space pppp.pp space SS space HH xx represents the concentration, unit %VOL, range -999.99~+999.99; n indicates the temperature, unit ° C, ranging from -99.9 to +99.9. pppp.pp represents gas pressure, unit mbar, range 0000.00~9999.99; SS indicates the device status code. HH is the XOR check...

Optical sensor series 4)Calculation of check value The calculation method is XOR from the first byte backward one by one. At the end of the first 25 bytes, a one-byte check result is obtained, and the result is converted to two-character output. For example, if the result is 0X28, the characters' 2 'and' 8 'are the output results. If the characters are letters, the output is all uppercase. eg. Current density 0.00%VOL T e m p e r a t u r e 21.4°C P r e s s u r e 1001.01 mbar Output： +000.00 +21.4 1001.01 00 28 5）Status code table Condition Normal operation condition Optical path fault Absorption...
