Description

This semiconductor-based gas sensor module from Amphenol SGX Sensortech Sensortech employs a MEMS micro-hotplate sensing element to detect a broad spectrum of volatile organic compounds and provide an equivalent CO2 reading. The module is designed for plug-and-play operation, requiring no field calibration, which makes it ideal for embedded air quality monitoring systems.

The sensor features robust signal conditioning onboard, providing stable digital outputs via I2C or PWM. Its compact form factor and low power profile suit battery-powered or portable applications. The module operates within a 0°C to 50°C temperature range, making it suitable for typical indoor environmental monitoring.

Key Features

  • Calibration-free semiconductor sensor for simplified deployment.
  • Dual-parameter output: tVOC concentration and eCO2 equivalent value.
  • Selectable digital communication via I2C (with 4.7kΩ pull-up recommendation) or PWM signal.
  • Optimized for low-power operation at 3.3V DC (±5%), ideal for embedded systems.
  • Fast tVOC response time with a data refresh rate of 1 Hz.
  • Compact and durable PCB-mounted module with high resistance to shock and vibration.
  • Wide detection range for volatile organic compounds, supporting comprehensive IAQ assessment.

Applications

  • Indoor Air Quality (IAQ) monitors for smart homes and offices.
  • HVAC system demand-controlled ventilation and fresh air intake optimization.
  • Portable and wearable personal air quality exposure loggers.
  • Embedded sensing in IoT devices for environmental data logging.
  • Air purifier and filter efficiency monitoring systems.

Frequently Asked Questions

What is the required supply voltage for this sensor module?

The module requires a regulated 3.3V DC power supply with a tolerance of ±5%. It is critical to provide a clean, stable voltage within this range to ensure accurate sensor readings and prevent damage to the internal MEMS sensing element.

How do I communicate with the sensor? What are the pinouts?

The module provides two digital output options. For I2C communication, use Pin 2 (SDA) and Pin 4 (SCL); a 4.7 kΩ pull-up resistor on the master side is recommended. For a PWM output, use Pin 1, which provides a 30Hz signal with a duty cycle (5-95%) proportional to concentration; a typical 10 kΩ pull-up to 3.3V is required on this pin.

Does this sensor require calibration?

No, this is a calibration-free module. The sensor is factory-calibrated for its stated ranges (tVOCs and eCO2 equivalent). This feature significantly simplifies integration and long-term maintenance, as no user-level calibration routines are necessary.

What is the warm-up time and response time for this sensor?

The sensor requires approximately 15 minutes for initial warm-up and stabilization after power is applied. Once warmed up, the tVOC reading refreshes at a rate of 1 Hz, with a response time of less than 5 seconds to changes in concentration, making it suitable for dynamic air quality monitoring.
