CO2 carbon dioxide transmitter mounted sensor industrial gas transducer | Автомобили и мотоциклы

Carbon dioxide detectorBecause carbon dioxide is colorless and tasteless, it is difficult to detect in general, and too much inhalation can cause discomfort or affect the growth of living organisms. Carbon dioxide is a detector for detecting the concentration of carbon dioxide in the instrument, with high precision, long life, small size, easy maintenance and other characteristics, widely used in various fields such as fermentation process control, agricultural greenhouse, greenhouse CO2 concentration monitoring. A variety of output options.Product parameters:Measurement: infrared;Measurement range: 0 ~ 5000ppm (range can be selected)Resolution: 5ppm (0 ~ 2000ppm)10ppm (2000 ~ 5000ppm)20ppm (5000 ~ 10000ppm)Accuracy: + 50ppm + reading 5%Repeatability: + 30ppmResponse time: less than 30SPreheating time: 3 minutesOperating temperature: 0 ~ 50Working humidity: 0% ~ 90%RH (no condensation)Storage temperature: -20 ~ 60Working voltage: 12VLife: more than 5 yearsDetection time: every 10 seconds to detect the CO2 content of a gas chamber.Connection descriptionDC_IN: DC 12V input;GND: power supply negative;A+:RS485 positive endNegative end of B-:RS485;V_OUT::0-5V voltage output;GND: negative signal;A_OUT:4-20MA current output;GND: negative signal;Amount of communication protocolRegister address definition: 0= address, baud rate of 1=, 2=, buzzer, 3= alarm value, the real-time data of 4=, 5= alarm state.ExampleSend: 010300040001 CB C5Reception: 01030203 B9 D0 28Send command description:ExplainaddresscommandRegister addressNumber of registerscheckdata010300040001C5 CBAddress: the address of the device, which accounts for one byte, 16 band mode, the range is 01-FE;Command: the implementation of the operation, accounting for one byte, 16 hex mode, such as the 03 is to read data, the 05 is to write data;Register address: read and write the starting address of the register, accounting for two bytes, 16 Decimal mode;Register number: two bytes, 16 decimal mode, starting from the register address, to be operated by a number, such as the address is 01, the number is 02, that is, read the contents of the 2 01,02 registers;Check: two bytes, 16 decimal mode, using CRC16 to verify, high in the previous;Receive command descriptionExplainaddresscommandData lengthdatacheckdata01030203 D0B9 28Read command: 03ExampleRead a register: 010300040001 CB C5Read multiple registers: 01030001000354 0bWrite command: 05Write 00 register (address): 010500000004 CC 09Note: each time you can only write a register address;ExplainaddressWrite commandRegister addressdatacheckdata010500000004CC 09Matters needing attention1 power on each time waiting for 30 seconds to stabilize the data.2 equipment is not waterproof, avoid direct contact with water,3 carbon dioxide is a heavier gas, so that the air flow detection is accurate.4 avoid strong light directly to the sensor.
