Product catalog summary
Features:
S1003Y is a high-performance, cost-effective electrochemical gas sensor designed for carbon monoxide detection. It is suitable for household use and complies with UL2034 and EN50291 standards.

Specifications:
  • Detection Gas: Carbon monoxide
  • Range: 0-2000ppm
  • Maximum Overload: 5000ppm
  • Life: 5 years
  • Output Signal: 3-9nA/ppm
  • Resolution: 0.5ppm
  • Repeatability: <2% output value
  • Temperature Range: -20° to 60°C
  • Humidity Range: 15% to 90%
  • Response Time: T90≤60s
  • Zero Drift: <±10ppm
  • Long-term Drift: <5%/year

Working Principle:
The sensor operates using a two-electrode fuel cell mechanism. It maintains functionality despite changes in temperature and humidity, ensuring stable calibration.

Signal Amplification:
Output signals are amplified using a direct current-to-voltage operational amplifier. A feedback resistor determines the signal value, with a typical setup converting 5nA to 5mV.

Cross Interference:
The sensor's response to various gases is documented, showing minimal interference from substances like ethanol and hydrogen sulfide.

Precautions:
  • Soldering temperature should not exceed 280°C, and time should be under 1 second.
  • Avoid contact with organic solvents and high-concentration gases.
  • Do not block the venting surface.
  • Do not disassemble the sensor due to corrosive electrolyte content.

Sensitivity Figure 2 S1003Y temperature sensitivity characteristics (-20℃~+70℃) W orking principle The sensor contains a conventional two-electrode fuel cell sensor. The working electrode releases electrons to the counter electrode through the external circuit, and is consumed at the end of the counter electrode as oxygen decreases. The internal circuit is realized by the ion current in the electrolyte. The design is well designed to facilitate the growth and decline of the electrolyte. The growth and decline of the electrolyte varies with changes in ambient temperature and humidity, but it can...
