Wireless CO2 sensor with LED indication - MIDAM WRU90089
Wireless, battery powered room sensor. The device features temperature, humidity and CO2 sensors. Native modbus map that grants seamless integration into the DDC/ SCADA system. CO2 values are indicated through 3 colour LED in “traffic light“ pattern. The communication is based on the AES128 encrypted Midam KFP protocol, which allows to update the device firmware on a wireless basis.

Funtion
The wireless sensor WRU90089 measures temperature, relative humidity and CO2 values. These are transmitted through the 868 MHz unlicensed band to the WCOM51, or WCOM01 gateways. Embedded AES 128-bit, provides the most secure encryption standard for wireless connections. Three LEDs indicate the CO2 values in so called traffic light pattern in fully adjustable threshold fo each color/level. There is also an option with rotating knob and display available ( refer to WRU90001 HMI room unit ) to provide a variety of possibilities for building up a project. The device has factory-set values to ensure the correct default function and allows direct reading and writing of values to the Modbus map, which is available in a separate document. All settings are also stored in the Modbus map directly in the device. Before using the device for the first time, it is necessary to pair it and it is recommended to perform individual configuration, especially to change the encryption password.
Application
- HVAC Control
- Temperature, Humidity and CO₂ Measurement
- Wireless Integration into SCADA Control Systems
- CO₂ Indication (LED Indicators)
Pairing
Two devices are required for mutual communication. Both must be powered and located in close proximity to each other. Usually, wireless gateway or configuration dongle is used to set up remote wireless devices. Use look-up function in software tool to display a list of all available devices in range and assign or adjust parameters based on wireless ID code for each single device. There is a comprehensive help section integrated in the software tool to provide support during the wireless device set up procedure.
SCADA system integration
The controller can be integrated into DDC or SCADA systems directly via the WCOM51, or WCOM01 wireless gateways.
Midam KFP Password change
Prior to the first use, the encryption password (default “MIKROKLIMA1234AB”) must be changed using the WUSB01 configuration dongle and the relevant software tool.
