Indoor air quality is becoming a growing concern as people spend more time indoors—whether at home, in the office, or in public facilities. From volatile organic compounds (VOCs) to carbon monoxide and formaldehyde, harmful substances can silently affect human health. One of the most reliable solutions for real-time monitoring is the PS-VOC-E air quality module, a compact yet powerful sensor designed to detect a range of harmful gases and help ensure cleaner air.

In this article, we’ll answer the most frequently asked questions about the PS-VOC-E air quality module, including its applications, working principles, technical parameters, and integration tips. Whether you're an engineer, product developer, or a buyer in the air quality industry, this guide will give you the insight you need.

1. What is the PS-VOC-E Air Quality Module?

The PS-VOC-E air quality module is a highly integrated gas sensor designed to detect total volatile organic compounds (TVOCs), ethanol, and other harmful gases in indoor environments. It is based on advanced semiconductor gas sensing technology and features a built-in signal processing circuit for reliable and fast measurements

It is especially useful in smart home systems, HVAC controls, air purifiers, and environmental monitoring devices where compact size and energy efficiency are essential.

2. What Gases Can It Detect?

The PS-VOC-E is primarily tailored for detecting TVOCs, including common pollutants such as:

Ethanol

Formaldehyde (HCHO)

Benzene

Toluene

Xylene

It provides a real-time index of air quality based on the concentration of these gases and other volatile organic compounds, making it a useful general-purpose indoor air quality indicator.

3. How Does the PS-VOC-E Work?

The module works by utilizing semiconductor-based sensing elements, which react with specific gases in the air. When VOC molecules come in contact with the sensor surface, the resistance of the semiconductor changes, which is then interpreted as a gas concentration value.

The PS-VOC-E also comes with built-in algorithms to convert raw resistance data into meaningful air quality metrics. This enables product developers to directly incorporate it into consumer electronics with minimal processing.

4. What Are the Technical Specifications?

Here are some of the typical technical parameters of the PS-VOC-E module:

Detection Range: 0-5ppm

Response Time: <90s

Power Supply: 4.5-7V

Digital Output: TXD (0～3.3V data output)

Operating Temperature: -40℃~70℃

Operating Humidity: 10％－90％RH (non-condensing)

Lifetime: Over 5 years in normal indoor environments

These specs make the PS-VOC-E ideal for long-term integration into indoor air quality solutions.

5. Where Can the PS-VOC-E Be Used?

The module is widely adopted across multiple sectors:

Smart home devices: Air purifiers, smart thermostats, ventilation control systems

Consumer electronics: Wearable air quality monitors, handheld detectors

Automotive: In-cabin air monitoring systems

Industrial applications: Workplace safety monitors, factory automation

IoT systems: Smart buildings and environmental monitoring stations

Its small size and low power consumption also make it ideal for battery-operated devices.

6. How Easy Is It to Integrate into Products?

The PS-VOC-E module is plug-and-play, featuring standard digital interfaces like I²C and UART. It also includes built-in calibration and automatic baseline correction, reducing the need for frequent recalibration.

For developers, detailed datasheets and reference designs are available, making hardware and software integration straightforward. Whether you’re prototyping or moving into mass production, the PS-VOC-E minimizes development time and risk.

7. How Accurate Is the PS-VOC-E?

While VOC readings can vary based on the environment, the PS-VOC-E provides consistent, stable readings under normal indoor conditions. Its intelligent baseline tracking algorithm helps reduce false readings due to sensor drift, humidity, or temperature changes.

It’s important to note that this module is designed for air quality indication, not for precise quantitative analysis of individual gases. For applications requiring exact measurements of specific gases, additional specialized sensors may be recommended.

8. Is the PS-VOC-E Safe and Environmentally Friendly?

Yes. The PS-VOC-E is designed to be RoHS compliant and environmentally safe. It uses no harmful chemicals, and its long operational life reduces electronic waste. This aligns with modern standards for sustainable and eco-conscious product design.

9. Who Manufactures the PS-VOC-E Module?
