The ZMOD4510 in OAQ 1st Gen operation will respond to typical outdoor gases after a warm-up time of 60 min, consisting of 20 min for stabilization and 40 min for baseline finding. For OAQ 2nd Gen operation a response to ozone will be seen after a warmup time of 30 min. In all operation modes a conditioning period of 48 hours followed by a sensor module restart in an ambient environment is recommended to improve stability and obtain maximum performance

Introduction

The ZMOD4510 Outdoor Air Quality (OAQ) sensor is an ultra-compact pre-calibrated digital sensor designed for reliable outdoor air quality detection. These sensors enhance energy efficiency during continuous operation, with a power consumption of less than 23mW without compromising air quality. The ZMOD4510 sensor features electrical and gas calibration, verified MOx material, digital (I2C) output, and silicone resistance. This device offers leading sensitivity and long-term stability, enabling ppb detection limits. These sensors correlate with the U.S. Environmental Protection Agency (EPA) Air Quality Index (AQI). Typical applications include urban air monitoring stations, personal monitors (including wearable devices), smart fans, and home and building automation systems.
