Product Overview

The ZMOD4410AI1V is a gas sensor module designed for detecting total volatile organic compounds (TVOC) and monitoring indoor air quality (IAQ) in different use cases. It is a 12-pin LGA assembly (3mm x 3mm x 0.7mm) that consists of a gas sense element and a CMOS signal conditioning IC. The module's sense element consists of 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 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.
  • Algorithm to set a control signal to trigger an external action based on IAQ and odour change
  • Heater driver and regulation loop for constant heater voltage or constant heater resistance
  • Internal auto-compensated temperature sensor; not stress sensitive
  • Configurable alarm/interrupt output with static and adaptive levels
  • Adjustable ADC resolution
  • Built-in non-volatile memory (NVM) for user data
  • Very low average power consumption down to 1mW
  • Excellent for low-voltage and low-power battery applications
  • No external trimming components required
  • External reset pin (active-LOW)
