Hydrogen Gas Smart Sensing Module
IDT’s SMOD701 is a complete smart sensing solution for
measuring hydrogen (H2) gas in the parts per million range. The
module, consisting of the SMOD smart sensing platform combined
with IDT’s SGAS701 H2 sensor, provides an indication of hydrogen
gas measured both as resistance and as a linear response
proportional to ppm of H2. The SMOD701 communicates with an
external controller or a data logger via a USB interface, and can be
supplied with an I2C or UART interface by special order.
The SGAS701 sensor can be supplied separately from the
SMOD701 Smart Sensing Module. See the SGAS701 Datasheet
for more information.

Typical Module Response
Figure 2 and Figure 3 show the typical response and selectivity of the SMOD701 module when operated in clean, dry air.
Typical H2 Response:
Air applied for 300 seconds, then H2 in
air for 300 seconds, followed by air
Rs = Resistance in displayed gas
R50 = Resistance in 50ppm H2
Gas Concentration (ppm)
