Description
The ZMOD4510 Evaluation Kit (EVK) is designed for evaluating
IDT’s ZMOD4510 Gas Sensor Module for Total Outdoor Air Quality
(OAQ). The sensor module is optimized for the detection of trace
atmospheric gases, including nitrogen oxides (NOx) and ozone
(O3) and reporting an Air Quality Index (AQI) based on the standard
of the US Environmental Protection Agency (EPA).
IDT’s Gas Sensor Evaluation Software allows Windows®-based
operating systems to communicate with the ZMOD4510 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 ZMOD4510 module mounted
on the ZMOD4510 Sensor Board (i.e., daughter board). Note: Only
one Communication Board with one Sensor Board can be
connected to the computer at a time.
The ZMOD4510 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.

1. Setup
1.1 Required or Recommended User Equipment
By default, the internal supply voltage for powering the Sensor Board is generated from the USB voltage supplied by the user’s computer via
the USB cable. If there is a need for currents higher than the defined USB standard (usually 500mA at 5V), an external voltage supply source
can be used instead of the internally generated voltage supply provided on the Communication Board.
The external supply only powers the sensor modules, and not the communication board itself. The supply must meet the following requirements:
Voltage – 1.7V to 3.6V
Current must meet the user’s specifications – The minimum is 30mA for electronics with additional current needed for each gas sensor
module of approximately 11mA (with a 1.8V voltage supply).
1.2 User Computer Requirements
1.2.1 Computer Requirements
A Windows-based computer is required for interfacing with the EVK and configuring the ZMOD4510. The user must have administrative rights
on the computer to download and install the Gas Sensor Evaluation Software.
The computer must meet the following requirements:
1GB RAM
Hard drive with at least 250MB free space
1 USB port
Windows Vista
®
/Windows 7®/Windows 8®/Windows 10®
Internet access for initial download of the drivers and software
Important: Before installing and activating the software, assemble and connect the hardware for the kit to the user’s computer according to
steps 1 through 3 in “EVK Hardware Connections and Initial Power-up.”
1.3 Software Installation and Setup
Before using the Gas Sensor Evaluation Software, the USB drivers for the FTDI device must be installed. Download the drivers and
corresponding installation guides from the FTDI website (www.ftdichip.com). The drivers will not affect the operation of any other USB
peripherals. The kit does not need to be connected during installation of the drivers.
Complete the following procedure to download and install the ZMOD4510 Evaluation Software with the kit connected:
1. Download the ZMOD4510 Gas Sensor Evaluation Software zip file at www.IDT.com/ZMOD4510-EVK.
2. Create a folder on the user’s computer for the software (e.g., C:\Program Files (x86)\IDT Software). Extract the contents of the
downloaded zip file into this folder.
3. Double-click on the extracted executable file Gas_Sensor_Evaluation.bat to start the software each time the program is used and
select the ZMOD4510 – Outdoor Air Quality option. Figure 1 shows the initial display after execution.

1.4 EVK Hardware Connections and Initial Power-up
To set up the EVK hardware before using the software, complete the following procedure:
1. Refer to Figure 2, Figure 3, and Table 1 to determine the correct jumper settings for the ZMOD4510 Communication Board depending on
whether an external supply or the internal voltage supply on the board is used.
If the internal voltage supply is used, ensure that the jumper is across the pins labeled “int” on the K2 connector.
If using an external supply, ensure that the jumper is across the pins labeled “ext” on the K2 connector. In this case, without
connecting the external supply to the Communication Board, verify that the external voltage supply setting does not exceed the
voltage supply specifications (i.e., a minimum of 1.7V and a maximum of 3.6V) as per the ZMOD4510 Datasheet. With the external
supply off, connect the external voltage to the 2-pin “+ - V ext” header adjacent to the K2 jumper with the orientation indicated in
Figure 3. Note: If this option is used, adjustments of the external voltage are not possible on either the Communication Board or the
Sensor Board for adjusting an external voltage supply.
2. Install the ZMOD4510 Sensor Board on the 14-pin connector on the Communication Board, taking care to ensure the proper orientation
of the Sensor Board as shown on page 1.
3. Insert the micro-USB cable into the X1 connector on the Communication Board and connect it to a free USB port on the user’s computer.
If the external voltage supply has been selected, turn on the external supply and verify that the D3 LED adjacent to the potentiometer is
on (see Figure 2). Note: The intensity of the green D3 LED is proportional to the supply voltage.
4. Activate the software as described in “Software Installation and Setup”.
5. If the internal voltage is used, the Gas Sensor Evaluation Software activates the internal voltage after the sensor has been started. Use
the metal potentiometer to the left of the K2 connector to adjust the VDD supply voltage in the typical range from 1.7V to 3.6V as
measured across the V_TGT and GND pins available on the K3 connector as shown in Figure 3. Its initial adjustment on delivery
provides a voltage of VDD ≈ 2.0V. Once a measurement has been started by the software, the green D3 LED adjacent to K2 will light
with an intensity proportional to the voltage supply that was set using the potentiometer.
6. Verify that the red D1 LED is on, which indicates that the kit is properly connected and powered (see Figure 2).
The Communication Board provides the additional K3 and Modul1 connectors for the following optional uses as described in Table 1. To make
use of any of these options, contact IDT for further instructions (see contact information on last page).
Extra measurement options (e.g., current consumption to determine the power requirements of the ZMOD4510)
Connections for additional sensors (e.g., IDT humidity sensor HS3001)
