MaiYa MST-N7M NDIR CO sensor

Product catalog summary

Overview: The MST-N7M N2O Datasheet provides detailed specifications for a CO gas sensor designed for environmental detection, gas leak monitoring, and online monitoring systems. The sensor operates on the Non-dispersive Infrared (NDIR) principle.

Specifications:

Measuring Range: 0-10000 ppm
Linear Error: ±2% Full Scale (F.S.)
Response Time (T90): ≤25 seconds with waterproof breathable film
Resolution: 10 ppm
Repeatability: ≤±1% F.S.
Operating Temperature: -20℃ to 60℃
Storage Temperature: -40℃ to 85℃
Humidity Range: 0 to 95% Relative Humidity (RH)
Warm-up Time: 1 minute

Signal and Power:

Digital Signal: Modbus RTU at 38400 bps
Analog Signal: 0.4 to 2V
Power Supply: 3.3 to 6V DC
Current: 45mA average, 180mA max
Power Dissipation: 0.23W 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% F.S., 2.2V indicates overrange

Additional Features: The sensor is noted for its long life and regular 7-series size, which facilitates ease of use.
