ZigBee technology is designed for use in wireless sensor networks, home automation and industrial monitoring and control systems. ZigBee networks do not require frequency resolution, provide high noise immunity and low power consumption. Thanks to their cellular topology, they have the ability to self-organize and self-heal.

The built-in ZigBee module allows you to use the sensor when it is not possible to lay an RS-485 bus. And also acts as ZigBee router and can be used to expand the network in wireless smart homes.

WB-MSW-ZIGBEE v.4 has an infrared transceiver for recording signals from IR remote controls of household devices and further control of household appliances: air conditioners, TVs, thermal curtains etc.

The sensor's non-volatile memory can store up to 80 IR commands. Commands are recorded using the remote control equipment.

Working with IR commands is described in detail in documentation.

CO2 (carbon dioxide) is a colorless gas with a slight sour odor, heavier than air. It is always present in the air and is harmless to humans in small quantities. CO2 does not support breathing, so at high concentrations it negatively affects a person’s condition and can lead to death from suffocation.

WB-MSW-ZIGBEE v.4 uses a non-dispersive infrared (NDIR) sensor to measure CO2 concentration. It allows measurements with an error of 100 ppm + 5% of the measured value.

Volatile organic substances (VOCs, VOC) are substances released into the atmosphere in the form of gases: evaporation of varnishes/paints and elements of interior decoration (phenol, formaldehyde, toluene, styrene), alcohols, benzene, rotting vegetables, gases emitted by humans, household gas. High concentrations of hazardous VOCs pose a threat to human life and health.

The VOC sensor determines the total concentration of these substances with a typical error of ±15%.

We develop and manufacture all Wiren Board devices ourselves. All devices undergo multi-stage quality control:

• During development — checking the components used for compliance with the declared characteristics and testing the prototype device at extreme operating conditions.
• After installing SMD components — automated optical inspection.
• After soldering the lead components — visual inspection of soldering.
• After assembling the device — functional testing on an automated stand.
• When shipped to the warehouse — control of completeness, stickers, appearance.

Thanks to this approach, the failure rate is no more than 0.5% of all released devices. Read more in the article About device reliability.

If the device fails within two years from the date of purchase, we will replace it for free without the need to send it to a service center.

You can configure the device in the zigbee2mqtt web interface, as well as by writing JSON commands to the MQTT-topics of the device using MQTT Explorer or wb-rules.

If the sensor is connected via Modbus RTU, then the configuration is performed in the controller’s web interface.

The sensor can be used with the Wiren Board controller and other devices with SprutHub or zigbee2mqtt 1.32.2.

If a Wiren Board controller is used, the measured values are available in the controller's web interface and can be used in automation scripts or transferred to a higher-level system.

The sensor can also transmit data via Modbus RTU (RS-485), which can be read by any equipment or software that supports this protocol: third-party controllers, HMI panels or SCADA.

The device complies with Directive 2014/53/EU
