FireStingO2-Mini (FSO2-MINI-ST)

Manual

Based on the technology of the USB-device FireStingO2 we developed the compact 1 channel module FireStingO2-Mini for OEM applications. The technical performance of the FireStingO2-Mini is identical to the normal FireStingO2 with 1 oxygen channel. There are only two principle differences:

(1) Due to space limitations there is no dedicated connector for the external temperature sensor, but the cable of a temperature sensor (4-wire PT100) can be soldered directly to the FireStingO2-Mini.

(2) The FireStingO2-Mini has no integrated USB-port. It offers a standard UART interface for integration in custom electronics (details on request). However, we optionally offer an external USB adapter cable FSO2-MINI-USB including a licence for the Pyro Oxygen Logger software. When connected to this USB adapter cable, the FireStingO2-Mini can be comfortably configured and operated with a PC using the versatile Pyro Oxygen Logger software.
