Frequently Asked Questions

What is the operating voltage range for the Winsen ZE40B-TVOC module?

The module operates from a 3.7V to 5.5V DC power supply. This range makes it compatible with common 3.3V and 5V microcontroller logic levels, such as those found on Arduino, ESP32, and Raspberry Pi boards. Ensure your power source is stable within this range for optimal sensor performance and longevity.

What output interfaces does this TVOC sensor provide?

The ZE40B-TVOC provides two output interfaces: a digital UART serial interface operating at 3V logic levels and an analog voltage output. The UART interface allows for direct digital communication and configuration with a host controller, while the analog output provides a simple voltage proportional to the TVOC concentration for basic readouts.

How do I calibrate or maintain the Winsen ZE40B-TVOC sensor?

The sensor is typically factory calibrated. For maintenance, it requires a brief pre-heat time of up to 3 minutes upon power-up for stable readings. The electrochemical sensor element has a finite lifespan of approximately 2 years in normal atmospheric conditions. Exposure to high concentrations of target gases or certain contaminants can shorten its operational life.

What gases does this sensor detect, and what are common interferences?

The primary target gas is Total Volatile Organic Compounds (TVOC). The electrochemical principle offers good selectivity, but like most VOC sensors, it can be cross-sensitive to other reducing gases. The datasheet notes potential interference from gases like carbon monoxide (CO). For critical applications, consult the full datasheet for detailed selectivity data.
