High-concerned chemical: None Model: ZMOD4510 Sensor category: Air Quality Sensor The ZMOD4510 Outdoor Air Quality (OAQ) sensor is a sub-miniature pre-calibrated digital sensor designed for reliable outdoor air quality detection. These sensors improve efficiency during continuous operation, with power consumption below 23m W, without affecting air quality. The ZMOD4510 sensor features electrical and gas calibration, proven MOx materials, digital () output, and silicone resistance. The device has leading high sensitivity and long-term stability, enabling ppb detection limits. These sensors are correlated with the U.S. Environmental Protection Agency (EPA) Air Quality Index (). Typical applications include urban air monitoring stations, personal monitors (including wearable devices), smart fans, and home and building automation systems.
