XPSN401A-G01E1 Carbon Dioxide NDIR Infrared Gas Sensor
Model: XPSN401A-G01E1
Ningbo Xingpu XPSN401A-G01E1, 0 – 5% VOL range, low-power NDIR infrared detection
The Ningbo Xingpu XPSN401A-G01E1 is a low-power miniature NDIR (Non-Dispersive Infrared) gas sensor with diffusion gas inlet and dual-wavelength optical path. It measures target-gas concentration by infrared absorption, with average operating current below 1 mA and average power consumption below 2.7 mW@3.3V. It provides both analog signal output and UART digital output for concentration, temperature and humidity data. Carbon Dioxide detection range is 0 – 5% VOL, repeatability ±1% FS or ±2% of reading, linearity accuracy ±3% FS or ±5% of reading, T90 response time ≤ 20 s and warm-up time ≤ 5 s. With dimensions of only φ20 × 16.6 mm and weight ≤ 10 g, it meets intrinsic safety explosion-proof requirements and offers a 5-year designed lifetime — ideal for portable instruments, wireless monitoring nodes, industrial safety alarms and HVAC refrigerant leak detection where low power, compact size and long-term stability matter.
