Renke RS-H2S-N01-2-100P-2 Hydrogen Sulphide & Temperature/Humidity Sensor - RS485 Modbus, Wall Mounted

The sensor uses the RS485 physical layer with the standard Modbus-RTU protocol. You can configure the communication parameters, including the slave address and baud rate, by sending specific Modbus commands to the device, allowing it to be integrated into multi-drop networks with PLCs, SCADA, or data acquisition systems.

The sensor operates on a wide-range DC power supply of 10 to 30 volts. It features a low power consumption of only 0.12W. Typically, wiring involves connecting the positive and negative power lines along with the RS485 data lines (A/B or D+/D-) to your host controller or converter, following standard industrial wiring practices.

Yes, the integrated electrochemical H2S sensor will require periodic calibration against a known standard gas concentration to maintain measurement accuracy, as is standard for all gas detection equipment. This sensor is specifically designed to detect Hydrogen Sulfide (H2S) gas; it is not cross-sensitive to other common gases.

The sensor is housed in a wall-mounted, waterproof enclosure designed for durability. While suitable for sheltered outdoor locations (e.g., under eaves, in instrument boxes), for full exposure to harsh weather, verifying the specific IP rating from the manufacturer's datasheet is recommended to ensure it meets the environmental demands of your application.
