Quickly integrate Sulfur Dioxide sensing into your system with very low power consumption and a simple analog sensor signal output. The ULPSM converts the Sulfur Dioxide sensor’s linear current signal output to a linear voltage signal, while maintaining the sensor at its ideal biased operation settings.

Key Features
  • 0 to 3 V Analog Signal Output
  • Low Power Consumption <45 uW
  • Fast Response
  • On-board Temperature Sensor
  • Easy Sensor Replacement
  • Standard 8-pin connector
  • Fixed Industrial Safety Monitoring
  • Portable Industrial Safety Monitoring
  • Portable Personal Safety Monitor
  • Indoor Air Quality Monitoring
  • Outdoor Air Quality Monitoring
  • Air Purification Control

Q: What is the measurement range of this SO2 sensor module?

A: The measurement range of the sensor is 0 to 20 parts per million (ppm).

Q: How does the ULPSM-SO2 module work?

A: The ULPSM-SO2 converts the SO2 sensor's linear current signal output to a linear voltage signal while maintaining the sensor at its ideal biased operating settings.

Q: What is the power consumption of this module?

A: The module is designed for ultra-low power consumption, which is important for battery-operated applications. However, the exact power consumption is not specified in the product description.

Q: What is the response time of the sensor?

A: The response time (T90) is less than 30 seconds, meaning it takes less than 30 seconds for the sensor to reach 90% of its final reading.

Q: What applications is this SO2 sensor module suitable for?

A: This sensor module is ideal for applications that require monitoring sulfur dioxide levels, such as air quality monitoring, industrial safety, and environmental sensing.
