The IDT Gas Sensor Advantage

IDT's gas sensor portfolio features trace hydrogen, industrial organic chemical (including VOC, TVOC), and flammable gas sensors, respectively. 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. IDT's gas sensing technology has a proven track record in real-world applications dating back more than 10 years.

Gas Sensor Evaluation Modules Available

The SMOD7xx evaluation module is an MCU-based solution encompassing all measurement and control aspects of IDT’s gas sensors. Each factory-configured SMOD7xx evaluation module senses a specific gas type. They connect to a Windows PC via a bi-directional USB connection, complemented by a software GUI. The sensor response is measured in both native resistance units and linearized concentration units. The SMOD7xx evaluation modules can be made available to system integrators. UART and I2C interfaces are optional, and all sensor operating parameters are customizable.

About Gas Sensors for Leak Detection and Indoor Air Quality (IAQ) Applications

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 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).
