IDT ZMOD4410 User Manual

Description
The ZMOD4410 Evaluation Kit (EVK) is designed for evaluating
IDT's ZMOD4410 Gas Sensor Module for TVOC. The total volatile
organic compounds (TVOC) measurement is one of the indicators
for indoor air quality (IAQ). In addition, a measurement mode is
provided to trigger an external device (e.g., fan, ventilation) based
on the air quality change.
The ZMOD4410 Evaluation Software allows Windows
operating systems to communicate with the ZMOD4410 EVK via a
USB connection on the user's computer, which functions as a
master. The software and additional related documentation is
available on the IDT website.
The EVK's Communication Board (HiCom) handles the interface
between the user's computer and the ZMOD4410 module mounted
on the ZMOD4410 Sensor Board (Daughter Board). Note: Only one
Communication Board with one Sensor Board can be connected to
the computer at a time.
The ZMOD4410 Evaluation Kit uses an FTDI controller on the
Communication Board to handle the USB protocol, translate
communications, and synchronize communications with the I2C
interface. The Sensor Board includes a decoupling capacitor.
The Communication Board has devices mounted on both sides.
The components on the top side generate a stable supply voltage.
A potentiometer can be used to adjust the internal supply voltage
in the typical range from 1.7V to 3.6V. Alternatively, the user's
external supply voltage can be used. The intensity of the adjacent
LED is proportional to the supply voltage.
