The 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 UART interface by special order.
The SGAS701 sensor can be supplied separately
from the SMOD701 Smart Sensing Module. For more
information, see the SGAS701 Datasheet.
