The only differences between the models are the number of sensors populated on the PCB. Because of different possible sensor configurations, Radiated Spurious Emissions have been tested with two different sensor configurations to evaluate if the different configurations have any effect on RF performance. These two tested different configurations are representative for both HVIN's. See differences listed in the table below: ECO ECO CO2 Tested Temperature Humidity Light CO2 NFC We attest that above changing are not relevant for any RF behaviour subject to regulatory items. Therefore, CTC advanced GmbH Test Report 1-7043_23-01-12_A and 1-7043_23-01-12_B remain applicable. If you have any questions, please feel free to contact us at the address shown below.

If there are several layers in the PCB, there is an advantage to add vias for smooth interconnection of the ground areas to avoid splits in the ground plane. It is also important that there is a ground clearance around the NC pads and the RF feed pad, through all layers of the PCB. It is recommended to implement a matching network to optimize the antenna impedance in your application. The components can be positioned under the antenna. See recommendations in the figures below.
