Description:Used in electronics, pharmaceuticals, air conditioning purification, food hygiene, hospitals, air freshening, etc

The dust sensor with high sensitivity has the characteristics of high measurement accuracy, convenient use, easy installation, small volume and long transmission distance

Supply voltage: DC 12- 24V@0

9WMeasuring range: 0 ~ 999 ug, air AOI indexWorking temperature: -10 ~ 65 degrees CelsiusWorking humidity: 0- RHStorage temperature: -20~+65 degrees CelsiusSignal output mode: 485 output @TTLCommunication protocol: ModBus_RTUBaud rate: VCC--connected to the positive pole of the power supply GND-connected to the negative pole of the power supply A--RS485_ A B--RS485_ BPackage Includes:1 piece dust transmitter 485 output (with shell)Note:Before installing and using this product, you should read the product instruction manual carefully

The power supply should not exceed the power supply voltage of the product, and pay attention to the polarity of the power supply

Do not measure under high temperature, high humidity and humidity

When using, the dust sensor should be kept clean

It must be installed vertically to ensure that the font on the transmitter is positive when installing the wall

The installation height is the sitting height of the human body or the main requirement measurement area

Keep away from artificial airflow, such as electric fans

When the probe of the dust sensor is wet, it will affect its normal function, so ensure that the dust sensor is not damp

When reading or modifying the address, you need to leave the 485 network and perform independent operations, otherwise the operation will fail

When connecting to a computer, you cannot directly use the 232 connection, you need to convert the 232 level to TTL level

Otherwise, the data read will be biased or garbled

Please refer to the dust transmitter ModBus protocol manual for specific instructions
