Renesas | ZMOD4410AI1R

The ZMOD4410 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 x 3.0 x 0.7 mm) 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 the gas concentration.

FEATURES

• Measurement of total organic compounds (TVOC) concentrations and indoor air quality (IAQ)
• Module algorithm estimates carbon dioxide level (eCO2)
• 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 maximum
• Siloxane resistant
