Sensirion SEK-SensorBridge Evaluation Kit for SEK

The standard interface between the SensorBridge and a computer is an USB Virtual COM Port, using a standard USB micro connector. This offers a fast plug-and-play interface to your computer and works seamlessly with the SEK-ControlCenter software. You can connect several SensorBridges on a computer for simultaneous evaluation of multiple sensors, limited mainly by the power consumption of the sensors and the capability of the computer. A powered USB hub is a good option for expanding your system, if necessary.
Additionaly, you can connect the SensorBridge via a RS485 interface, provided you also have a RS485 interface on your computer. This option allows connecting several SensorBridges on one bus and powering them by just one supply. Furthermore, long distances between the devices and a computer can be supported by the RS485 interface.
