Frequently Asked Questions

What gases does the ZMOD4450AI1V sensor detect?

The ZMOD4450AI1V is primarily a Volatile Organic Compound (VOC) sensor. It uses its VOC readings and advanced algorithms to provide an accurate estimation of equivalent Carbon Dioxide (eCO2) concentration, which is a key metric for indoor air quality assessment. It does not measure specific gases like CO or NO2.

What is the required supply voltage and communication interface?

This module operates from a low voltage supply range of 1.7V to 3.7V DC, making it compatible with many battery-powered and 3.3V logic systems. It communicates exclusively via the I2C (I²C) serial protocol, requiring connection to the SDA (data) and SCL (clock) lines of your host microcontroller, such as an Arduino, ESP32, or Raspberry Pi.

Is this sensor pre-calibrated, and what is its accuracy?

Yes, the Renesas ZMOD4450AI1V is factory-calibrated and provides a digital output via I2C. It boasts a high accuracy of ±2% for its eCO2 estimation within its specified range of 400 to 5000 ppm. This calibrated output simplifies integration, as no end-user calibration is typically required for basic air quality monitoring applications.

What are the typical applications for this sensor?

Its primary application is Indoor Air Quality (IAQ) monitoring in smart home devices (thermostats, air purifiers), HVAC systems for ventilation control, and portable wearables. Its low power consumption and small size also make it ideal for battery-operated IoT sensor nodes and embedded systems where space and energy are constrained.
