IDT offers innovative, high performance gas sensors for indoor air quality (IAQ) and industrial leak detection. IDT’s gas sensors are capable of accurate detection of Volatile Organic Compounds (VOCs), hydrogen and other flammable gases, and leverage advanced sensing materials with more than 12 years of proven stability and reliability.
IDT provides two gas sensor platforms to fit your needs: the ZMOD and SGAS. The ZMOD platform is an integrated digital gas sensor ideal for high volume consumer and industrial IAQ applications, while the analog SGAS family is best suited for industrial control and leak detection applications.
ZMOD Indoor Air Quality Gas Sensor Platform
The ZMOD4410 indoor air quality platform is an integrated digital sensor module offering:
- Chemical and electrical calibration
- Recognized indoor air quality definitions from the German Environment Agency (UBA)
- A flexible interface that enables software configurable indoor air quality sensing solutions for sensing VOCs and targeting applications in homes and offices
IDT has a rich history of shipping precision ASICs that are accurate, energy-efficient, and provide maximum flexibility through software-configurability. The combined experience of both sensing materials and sensing controls has created the industry’s most accurate and flexible gas sensing platform.
The ZMOD4410 gas sensor module is a firmware configurable platform that addresses air quality requirements in a wide range of IAQ applications such as smart homes and buildings, including thermostats, air purifiers, building controls, smart fans and smart HVAC equipment. For example, sources of VOCs in a home may vary by room. The ZMOD4410 offers a library of downloadable firmware to address these specific applications. If the application requires a battery-powered source, a low power firmware configuration can be downloaded, providing an optimized duty cycle operating within a restricted power budget.
IDT’s ability to provide a configurable sensing platform comes from three factors: materials, temperature, and time. The MOx material delivers outstanding sensitivity to air quality contaminants, with a well-controlled manufacturing process developed and demonstrated over many years. The ability to vary operating temperature and time at temperature comes from our innovative ASIC. These three parameters create a tunable system for reliable detection of a wide range of air contaminants. Our ZMOD platform can leverage critical parameters based on target gases to optimize sensitivity and provide the ultimate firmware-enabled gas detection platform. IDT’s advanced manufacturing supply chain, calibration and JEDEC-based qualification ensure best results for our customers.

SGAS Family Gas Sensor Solutions
IDT's SGAS gas sensor portfolio features trace hydrogen, industrial organic chemical (including VOC, TVOC), and flammable gas sensors. The devices utilize innovative sensing materials to achieve industry-leading stability. This results in fewer calibration cycles and longer product service life, which can save costs associated with replacing or recalibrating sensors in the field. In addition, superior gas sensitivity and selectivity enables customers to detect low-levels of gas, while avoiding false readings.

About Gas Sensors for Leak Detection and Indoor Air Quality (IAQ) Applications, VOC Sensors
A gas sensor (often called a gas detector) is a device used to determine the presence and amount of a specific gas or gases. At the core of any gas detection system is a sensor element. The gas sensor element is typically manufactured to detect a specific gas, and convert that measurement into an electrical signal that can be interpreted by the system. Several factors influence the quality of a gas sensor, including accuracy (how accurate is the measurement), sensitivity (detection of very low levels of gas), selectivity (how well it performs in the presence of other gases), and stability (how reliably it performs year after year).
IDT’s gas sensors provide industry-leading specifications, addressing industrial leak detection and indoor air quality (IAQ) applications. Options are available for measuring the presence of hydrogen gas, methane gas, propane gas, liquefied petroleum gas (LPG), and volatile organic compounds (VOCs), and total volatile organic compounds (TVOC).
MOx Sensor Technology Offers Superior Performance
MOx sensors, sometimes called chemiresistive sensors, are well known for their ability to offer affordable, reliable performance in harsh applications compared to non-MOx sensors. MOx materials and appropriate deposition methods that have been in use for more than 10 years ensure production of the most reproducible and reliable sensors that will enable you to safely predict the future performance of your products.
Liquefied Petroleum Gas (LPG) and Propane Gas Sensors
Liquefied petroleum and propane gas sensors are used to detect mixtures of hydrocarbon gases. These gases are used for fuel in heating appliances, cooking equipment, and vehicles. Unfortunately, these systems have the potential to leak small quantities of gas into the environment. While there are well established approaches to quantifying explosive levels, such as pellistors and non-dispersive infrared (NDIR) sensors, detection of trace or ppm levels is a challenge for many sensor technologies. The high sensitivity and fast response time of IDT propane gas sensors makes finding leaks easier.
Methane Gas Sensors
Methane gas sensors monitor the colorless, odorless, hydrocarbon gas. Quick detection of this gas is vital, as this is a contributor to climate pollution and global warming. While there are well established approaches to quantifying explosive levels, such as pellistors and non-dispersive infrared (NDIR) sensors, detection of trace or ppm levels is a challenge for many sensor technologies. The high sensitivity and fast response time of IDT methane gas sensors makes finding leaks easier.
