MSGS 3002 Methane Gas Sensor
Designed for use with Gas Sensing Microsystem, or MGSM3000 Gas Sensing Module. The MSGS-3002 structure consists of a doped tin-oxide (SnO2) thin-film layer over an embedded thin film heater (figure 1). This integrated heater resistance (RH) is used to control the sensitive layer temperature which is necessary for chemisorption reaction mechanisms to properly occur. These mechanisms modify the sensitive layer resistance (RS) by reversible electron charge transfer from surface states to the conduction band.
