Low-Power VOC Smart Sensing Module
IDT’s SMOD707 is a complete smart sensing solution for general
volatile organic compounds (VOCs). The module, consisting of
the SMOD smart sensing platform combined with IDT’s SGAS707
VOC sensor, provides an indication of total VOCs measured both
as resistance and as a linear response proportional to the
concentration of a representative VOC calibration gas (ethanol).
The SMOD707 communicates with an external controller or a
data logger through a USB interface, and it can be supplied with
an I2C or UART interface via special order.
The SGAS707 sensor can be supplied separately from the
SMOD707 Smart Sensing Module. See the SGAS707 Datasheet
for more information.

Typical Module Response
Figure 2 shows the typical response and selectivity of the SMOD707 module for detecting several applied VOC and non-VOC gases operated
in clean, dry air.
