Product information "MH-Z19C Infrared CO2 sensor, pin header"

The MH-Z19C infrared gas module is a small sensor that uses the non-dispersive infrared (NDIR) principle to detect the presence of CO 2 in the air. The sensor is characterised by good selectivity and works independently of oxygen. It has built-in temperature compensation and outputs the data via a UART or PWM output.
Compared to the previous model (MH-Z19B), the preheating time has been reduced from 3 to 1 minute and the power consumption reduced. The sensor calibrates itself every 24 hours (can be switched on and off by command), but a zero-point calibration can also be activated manually.

Technical data:
  • Model: MH-Z19C
  • Target gas: CO2
  • Operating voltage: 5 V DC (±0.1V)
  • Average current consumption: < 40mA (@5V)
  • Peak current: 125mA (@5V)
  • Interface level: 3.3 V (compatible with 5V)
  • Measuring range: 400 - 5000 ppm
  • Accuracy: ± (40ppm+5% measured value)
  • Output signal:
    • UART (TTL interface level 3.3V)
    • PWM
  • Preheating time: 1 minute
  • Response time T90 < 120 s
  • Operating temperature: -10 - 50 ℃
  • Operating humidity: 0 - 95% RH (no condensation)
  • Dimensions: approx. 33 × 20 × 17 mm
  • Connection: pin header with 2.54 mm pitch
  • Scope of delivery: CO2 sensor

Sensor funktioniert am Rasberry Pi ohne Probleme. Einzig der Abstand der PIN-Reihen ist so groß das ich das nur über zwei Mini Breadboards (170 Kontakten) installieren konnte.

Der CO2-Sensor funktioniert gut. Die Backgroundcalibration ist etwas umständlicher als z.B. bei Senseair S8, aber dafür ist er auch etwas günstiger. Wichtig ist, das man keines der im Umlauf befindlichen Fakes des Sensors erhält. Deshalb habe ich auch hier bestellt und nicht in China.
