Overview
Description
The ZMOD4510 gas sensor platform detects air quality in a variety of indoor and outdoor applications. The module is a 12-pin LGA assembly (standard version 3.0mm x 3.0mm x 0.7mm) that consists of a gas sense element and a CMOS signal conditioning IC. The module’s 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 resistance, which is a function of the gas concentration.
The freely available firmware enables different ZMOD4510 features based on traditional and machine learning algorithms with embedded artificial intelligence (AI) using the same hardware platform. This is used to determine the Air Quality Index (AQI) output, which is based on the gases present. The measurement results can be read via an I2C interface with the user’s microprocessor, which processes the data to determine the levels of gases present and to indicate the AQI based on international standards. With its latest ultra-low power mode, the ZMOD4510 is an excellent choice for detecting ozone and nitrogen dioxide in indoor and outdoor applications.

ZMOD4510 warmup and timing question
Hi, I've been running some test on the ZMOD4510 and O3 concentrations never went up from 0, so there's probably something I'm doing wrong... Our application has to get O3 concentration every 20 mins. The implementation of the firmware is done in a way that performs the ...

RX Family: CK-RA6M5/CK-RX65N is used. I can only read 00h data from the outdoor sensor (ZMOD4510) installed in the same kit. Is it malfunctioning?
The ZMOD4510 (outdoor sensor) in the CK-RA6M5 and CK-RX65N requires a warm-up time. This time varies depending on the operating mode of the sensor.It is 60 minutes when operated in Gen1 mode and 42 hours in Gen2 mode.Also, since this warm-up time is required ...
