  • Linear Error: ±2% Full Scale
  • Response Time (T90): ≤25 seconds with waterproof breathable film
  • Resolution: 1 PPM
  • Repeatability: ≤±1% Full Scale
  • Operating Temperature: -20℃ to 60℃
  • Storage Temperature: -40℃ to 85℃
  • Humidity Range: 0 to 95% RH
  • Warm-up Time: 1 minute
Signal and Power:
  • Digital Signal: Modbus RTU 38400 bps
  • Analog Signal: 0.4 to 2V
  • Power Supply: 3.3 to 6 VDC
  • Current: 45 mA (average), 180 mA (max)
  • Power Dissipation: 0.23 W (average)
Pin Functions:
  • V+: VCC+ 3.3 - 6V
  • GND: VCC-
  • Tx: Serial port transmitter, TTL level 0 – 2.5V
  • Rx: Serial port receiver, compatible with 1.8-5V input
  • DA: Analog output, 0.2V indicates preheat, 0.4-2V corresponds to 0-100% Full Scale, 2.2V indicates overrange
Additional Features: The sensor is characterized by its long life and regular 7 series size and pin distribution for easy system integration.
