Overview

The PS1-VOC-500-MOD-I2C is a high-accuracy Volatile Organic Compound (VOC) sensor module designed for industrial and commercial air quality monitoring. It features a pre-calibrated electrochemical sensor combined with a digital output, supporting both I2C and UART communication for easy integration into embedded systems.

Why Choose This Part

The module offers a fast response speed and return to zero, coupled with excellent anti-toxicity and zero drift performance. It operates with a low run current of less than 5mA and includes a 100uA sleep mode, making it suitable for battery-powered IoT applications.

Applications

Indoor Air Quality Monitoring
Used in smart home systems and HVAC controllers to detect harmful gases and trigger ventilation.
Industrial Gas Detection
Monitoring for VOC leaks in chemical processing plants or storage facilities where accuracy and repeatability are critical.
Air Purifier Control
Integration into consumer air purifiers to automatically adjust fan speeds based on detected pollutant levels.
Commercial Building Management
Monitoring air pollution levels in office buildings, shopping centers, and other high-occupancy environments.

Key Specifications

Type Volatile Organic Compound (VOC)
Output I2C

Getting Started

Connect the module to a 3.3V to 5.5V power source and interface via the 4-pin SMD connector for I2C or UART communication. Developers should utilize the pre-calibrated digital output to read VOC concentration, temperature, and humidity values directly without the need for complex analog calibration circuitry.

Also Consider

SGP40 Sensirion - A more compact MOX-based VOC sensor with lower power consumption but different cross-sensitivity profiles.
CCS811 ams OSRAM - An ultra-low power digital gas sensor for monitoring indoor air quality that includes an integrated MCU for algorithm processing.
BME680 Bosch Sensortec - A combined environmental sensor that measures VOCs, humidity, pressure, and temperature in a single tiny package.
