| About | In this roadtest, you will have the opportunity of test the ZMOD4410 Gas Sensor Module, which is designed to detect total volatile organic compounds (TVOC) and monitoring indoor air quality (IAQ). The ZMOD4410 Sensor Module is conveniently mounted on a Raspberry Pi Hat by AVNET. Roadtesters will also receive a Raspberry Pi Raspberry Pi 3 Model B and 16GB SD Card.
About the Renesas ZMOD4410 Indoor Air Quality Sensor Module Providing best-in-class stability and sensitivity, the Renesas ZMOD4410 gas sensor module is designed to detect trace gases in various locations within indoor environments. It features embedded artificial intelligence (e-AI), enabling smart odor sensing for ventilation systems, bathroom monitoring and controls, and air quality monitors. It can be configured for use in individual rooms in homes and buildings, such as bathroom and kitchens, to solve unique air quality problems. The sensor is supplied with pre-compiled libraries.
It is a 12-pin LGA assembly (3.0 x 3.0 x 0.7 mm) that consists of a gas sense element and a CMOS signal conditioning IC. The module’s sense element consists of a heater element on a Si-based MEMS structure and a metal oxide (MOx) chemiresistor. The signal conditioner controls the sensor temperature and measures the MOx conductivity, which is a function of the gas concentration.
The measurement results can be read via an I2C interface with the user’s microprocessor, which processes the data to determine the TVOC concentration, IAQ rating and estimated carbon dioxide (eCO2) level. This flexibility makes the sensors in the ZMOD4410 sensor capable of providing a variety of measurement options by varying the method of operation or changing the firmware used to interpret the resistance measurements. Downloadable firmware libraries and source code provided by IDT enables detection of TVOC and odors and supports smart devices measuring IAQ that require low-power operation.
Features
– Measurement of total organic compounds (TVOC) concentrations and indoor air quality (IAQ) – Module algorithm estimates carbon dioxide level (eCO2) – Algorithm to set a control signal to trigger an external action based on IAQ and odor change – Algorithm to discriminate sulfur-based odors
About The Avnet ZMOD4410 IAQ Pi HAT To roadtest the ZMOD4410 Indoor Air Quality Sensor Module, element14 chose to use the Avnet Renesas ZMOD4410 Indoor Air Quality HAT built for Raspberry Pi. The HAT features an on-board calibrated ZMOD4410 sensor that measures the concentrations of Total Volatile Organic Compounds (TVOC) and can estimate carbon dioxide (eCO2) levels. In addition to the ZMOD4410 sensor, the HAT incorporates a Renesas HS3001 Precision Relative Humidity and Temperature Sensor, along with software-controlled status LEDs.
Features
In addition to the AVNET ZMOD4410 Pi HAT, we will be including a Raspberry Pi 3 Model B and a 16GB SD card. About the Renesas Software So far we've talked about the hardware in this roadtest. Let's now talk about the software. Since this is a commercial product, not an “open source." Hence, source code for the software is not provided. The Renesas is encrypted and requires a software license to download and obtain the binary libraries that make the sensor function.
1. To validate the HAT’s operation and begin measuring TVOC and eCO2 “out of the box” with a Raspberry Pi solution, Avnet provides a pre-compiled test application built with those algorithm libraries that runs under the Raspberry Pi operating system. You can download it here under "Software Downloads."
2. You can download Renesas’ Software License Agreement and procedure to download the ZMOD algorithm libraries and related confidential data by clicking here Scroll down to downloads and you will see files with a yellow lock icon:
Click the icon and you will be prompted to create a Renesas account. After your account is verified, you can click the file and you will be taken to the Secure Access Request. (Be patient. it takes some time to approve your account and get access.)

The ZMOD4410 sensor device is a small module containing a low-power programmable signal conditioning IC and a specially-developed MEMS gas sensing element. Under software direction, the ZMOD4410 precisely controls the internal temperature of its sensing element, allowing for the detection of a wide range of indoor air contaminants by accurately measuring the sensing element’s conductivity and resistance. This flexibility makes the ZMOD4410 capable of providing a variety of measurement options by varying the method of operation or changing the firmware used to operate it. Downloadable libraries provided by IDT under license make upgrades straightforward to implement. All sensors are electrically and chemically (gas) tested with calibration data stored in the ZMOD4410’s built-in nonvolatile memory.
Note that the associated libraries may be obtained from IDT; they are not included with the Avnet ZMOD4410 Indoor Air Quality Sensor Raspberry Pi Hat. To validate the Hat’s operation and begin measuring TVOC and eCO2, Avnet provides a pre-compiled application built with those libraries which runs under Raspbian, the official supported operating system for the Raspberry Pi. In addition to the ZMOD4410, the Hat includes an IDT HS3001 Precision Relative Humidity and Temperature Sensor, along with software-controlled status LEDs.
