Combined digital sensor for temperature and humidity.
A wireless version: WB-MSW-ZIGBEE v.4.
Main characteristics
- 2 measured parameters in one housing.
- Heated temperature and humidity sensor for operation in high humidity conditions.
- Fast and simple integration into the automation and monitoring system.
- It is possible to apply your company logo.
Supports Fast Modbus, allowing motion sensor events to be instantly delivered to the Wiren Board controller.

Measured parameters:
- Temperature: -40°С…+80°С (±0.5°С).
- Humidity: 0…95% (±3%).
- Two-color indication controlled via Modbus.
- Sensor heating for operation in high humidity conditions.
- Supply voltage: 9 to 28 VDC.
- Power consumption: from 0.5 to 4 W.
- Interface: RS-485, Modbus RTU.
- Plastic case with the possibility of mounting on a socket box (80x80x19 mm).

All Wiren Board devices, in addition to the standard Modbus RTU, can work with its extension Fast Modbus ⚡, which adds new features:
- instant polling of input states and measured values via events;
- quick search for devices connected to the controller;
- resolving address collisions on the bus.
Additional features are enabled automatically — if the device supports the extension, the controller driver will use Fast Modbus. If the device does not support the extension, it will operate over standard Modbus RTU.

We develop and manufacture all Wiren Board devices ourselves. All devices undergo multi-stage quality control:
- During development — checking components and testing prototypes under extreme conditions.
- After SMD component installation — automated optical inspection.
- After soldering lead components — visual inspection.
- After assembly — functional testing on an automated test stand.
- Before shipment — verification of completeness, labels, and appearance.
Thanks to this approach, the failure rate is less than 0.5%. Read more in the article About device reliability .
If a device fails within two years from the date of purchase, we will replace it free of charge without the need to send it to a service center.

When used with a Wiren Board controller, you can configure the device in the web interface using a mouse:
- Enable or disable parameter polling.
When used with other equipment, the sensor can be configured via RS-485 by writing values to Modbus registers. The register table is open, well-documented, and available on our website.

If a Wiren Board controller is used, measured values are available in the controller's web interface and can be used in automation scripts or transferred to a higher-level system. Only enabled channels are shown in the device card.
The module also transmits all data over Modbus RTU (RS-485), which can be read by any equipment or software that supports the protocol: third-party controllers, HMI panels, or SCADA.
