Renke RS-PM-N01-2 Air Quality PM2.5 PM10 Sensor - RS485/0-5V/0-10V/4-20mA Output

The sensor provides a configurable output. You can select between RS485 communication using the Modbus RTU protocol for digital network integration, or analog outputs including 0-5V, 0-10V, or a 4-20mA current loop. This flexibility allows direct connection to PLCs, data loggers, and building management systems.

The sensor operates on a wide 10 to 30 VDC power supply. This range accommodates common industrial power sources like 12V or 24V systems. Ensure your power supply is stable and capable of providing sufficient current for the sensor's operation, typically under 100mA.

When configured for RS485 output, the sensor uses the standard Modbus RTU protocol. You will need an RS485-to-USB or RS485-to-serial converter to connect it to a PC or controller. Refer to the product datasheet for the specific Modbus register map containing PM2.5 and PM10 concentration values, baud rate, and parity settings.

The sensor has an accuracy of ±3% of full scale when calibrated at 100 µg/m³, 25°C, and 50% RH. It incorporates automatic calibration technology using dual-frequency data acquisition to maintain consistency (±10%) over time, reducing the need for frequent manual recalibration in stable environments.
