MH-Z19B NDIR CO2 Sensor
—The MH-Z19B is an NDIR carbon dioxide sensor that measures actual CO2 concentration in ppm, unlike the cheaper gas sensors that only infer air quality.
Specifications
- NDIR (non-dispersive infrared) measurement
- Range 0-5000 ppm, accuracy ±50 ppm ±5%
- UART and PWM outputs
- Automatic baseline calibration, disable-able
- 5V supply
- Warm-up about 3 minutes
What you can build with the MH-Z19B NDIR CO2 Sensor
- Classroom and office ventilation monitoring
- Home Assistant CO2 sensors
- Grow-room CO2 control
- Ventilation checks in New Zealand classrooms and offices
Compatibility
Works with Arduino, ESP32, ESP8266 and Raspberry Pi over serial. NDIR is the technology that gives real ppm figures; MQ-series sensors cannot do this regardless of how they are marketed.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
