Overview

IDT's ZMOD4410AI1V gas sensor module is designed for detecting total volatile organic compounds (TVOC) and monitoring indoor air quality (IAQ). It is a 12-pin LGA assembly (3.0 mm x 3.0 mm x 0.7 mm) that consists of a gas sensing element and a CMOS signal conditioning IC. The module’s sensing 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 ZMOD4410AI1V platform capable of providing a variety of measurement options by varying the method of operation or changing the firmware used to interpret the resistance measurements. IDT provides downloadable libraries and source code for the most common applications.Features: Measurement of TVOC and IAQ concentrations, Module algorithm eCO2 level, Multiplexed input channel for heater, resistance, and temperature measurements, Internal auto-compensated temperature sensor; not stress sensitive, I2C interface: up to 400 kHz, Configurable alarm/interrupt output with static and adaptive levels, Adjustable ADC resolution for optimal speed versus resolution: 16-bit max., Siloxane resistant
