Use this sensor to seamlessly connect real-world devices via USB. This GPIO device hides the complexity of USB. Modules can be connected to the ports on this USB sensor. Seven of the 8 port channels are pre-configured. The last port is available for an additional sensor module. The sensor controls and read status is accessed via CLI, SNMP, Restful APIs. Nodegrid device (Kibana).

**Hardware:**

- GPIO 8-port sensor
