The SMOD electronic module creates an easy way to evaluate the SGAS sensor. An MCU-based electronic module encompasses all measurement and control aspects of SGAS sensors. The factory configured SMOD functions with a specific SGAS sensor type. The SMOD board connects to a Windows PC via a bi-directional USB connection; supplied with an application facilitating SMOD operation. The sensor response is both native resistance units and linearized concentration units.  Sensor operating parameters are customizable.
