Renesas ZMOD4410 Gas Sensor Module

Featuring an easily integrated firmware architecture

The Renesas ZMOD4410 is a gas sensor module which features an easily integrated firmware configurable architecture enabling multiple sensing solutions with a common hardware platform. The JEDEC JESD47 qualified device supports indoor air quality (IAQ) application designed for detecting total volatile organic compounds (TVOCs), estimating CO2, and monitoring indoor air quality in different smell-based use cases, including very humid and dusty applications with the possibility of water spray, condensation or immersion.

The miniature 12-LGA assembly consists of a gas sense element and a CMOS signal conditioning IC. The sensor is pre-calibrated with a signal conditioner controlling the sensor temperatures 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.

The ZMOD4410 by Renesas is ideal for applications such as air purifiers, IAQ monitors, kitchen hoods, HVAC equipment, building controls, thermostats, smart fans, and other smart devices.

Simply download one of the firmware libraries that best supports your application from the Renesas website and integrate it with your host microcontroller.

Features

  • JEDEC JESD47 qualified for 10+ years of life
  • Firmware configurability output based on AI machine learning algorithmic:
    • Absolute measurement of total organic compounds (TVOCs) concentrations and indoor air quality (IAQ)
    • Estimated carbon dioxide level (eCO2)
    • Relative control signal to trigger an external action based on IAQ and odor change
    • Algorithm to discriminate sulfur-based odors
  • Built-in nonvolatile memory (NVM) for module-specific data (configuration and calibration)

 

  • Ultra-low average power consumption down to 160µW supporting battery applications
  • Siloxane resistant
  • Supply voltage: 1.7V to 3.6V
  • RoHS compliant
  • Water and dustproof version available (IP67 certified)
  • 12-LGA package with assembly sizes:
    • 3.0mm x 3.0mm x 0.7mm (standard version)
    • 3.0mm x 3.0mm x 0.9mm (for IP67 version)

Applications

  • Indoor air monitoring to meet UBA and typical Public Building Air Quality (PBAQ) standards
  • Monitor home, office, personal, and bathroom environments for healthy conditions and comfort
  • Detect hazardous materials and unhealthy conditions (e.g., fumes from construction materials)

 

  • Automation based on indoor ambient air quality (HVAC, air purifiers, thermostats, kitchen hoods, etc.)
  • Ideal for indoor and outdoor applications (wearables, health bands, etc.)
