WR-01 is an industrial device for continuous measurement of ambient temperature and relative humidity 🌬️. The device reads data from two 1-Wire interface channels and converts signals from independent relative humidity and temperature sensors into an RS-485 serial interface signal using the Modbus RTU protocol.

The device is designed for operation in non-aggressive gaseous environments, including ventilation, air-conditioning, and technological microclimate control systems.

In addition to converting and transmitting measurement signals, the device can perform alarm or control functions on two channels. This allows the WR-01 to be used not only as a communication module, but also as a local automation element for generating control or alarm signals depending on the values of the monitored parameters.

🔩 Functional features:

✅ Measurement of ambient temperature in the range from –40 °C to +75 °C, with a typical accuracy of ±0.5 °C.
✅ Measurement of relative humidity in the range of 0–100% RH, with a typical accuracy of ±2.0% RH.
✅ Display of current temperature and humidity values on the built-in OLED display.
✅ Local parameter configuration, including address, baud rate, filtering, and other settings, using the built-in buttons.
✅ Indication of operating modes, including power, error, and data transmission, via LED indicators.
✅ Digital filtering of measurements, which improves the stability of readings.
✅ RS-485 interface with Modbus RTU protocol for data transmission in industrial networks, remote parameter reading, and interaction with external controllers or SCADA systems.
✅ Two independent alarm channels.
✅ Power supply range: from 11 to 36 V DC.

The WR-01 is housed in a compact industrial enclosure with DIN-rail mounting capability, ensuring convenient installation in control cabinets, automation panels, and distribution cabinets. This mounting method simplifies connection, maintenance, and integration of the device into existing automation systems.
