ZMOD4510AI1V

The ZMOD4510AI1V is a gas sensor module detects outdoor air quality in a variety of indoor and outdoor applications. The module is a 12-pin LGA assembly (3mm × 3mm × 0.7 mm) that consists of a gas sense element and a CMOS signal conditioning IC. The module sense element consists of a heater element on a silicon-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 device is ideal for monitoring and reporting Total Outdoor Air Quality. The Air Quality Index (AQI) output is based on a combination of outdoor gases present, including nitrogen oxides (NOx) and ozone (O3).

• Supports international standards for total outdoor air quality
• Heater driver & regulation loop for constant resistance, minimize effect of temperature on signal
• Internal auto-compensated temperature sensor; not stress sensitive
• I2C interface: up to 400kH
• Configurable alarm/interrupt output with static and adaptive levels
• Built-in non-volatile memory (NVM) for module-specific data
• Low average power consumption in low mW range
• Supports low-voltage and low-power battery applications
• No external trimming components required
• External reset pin (active-LOW)
