Customer Questions & Answers
What exact dimensions and weight does the module have, and what is included in the box?
The module measures 33 mm long, 20 mm wide and 9 mm high; its weight is 21 g. The package includes 1 MH-Z19B sensor and 1 connection cable.
What tolerances and accuracy limitations does it have in typical environmental use ranges?
The specified accuracy is ±(50 ppm + 5% of the reading), valid within 0–5000 ppm, 0–50 °C and up to 95% relative humidity without condensation. In environments with condensation or outside those ranges, accuracy may deteriorate.
What maintenance does it require and how is its service life best extended?
The sensor does not require regular maintenance, but prolonged exposure to condensation, contaminants or extreme temperatures should be avoided. In critical applications, annual recalibration is advised to ensure accuracy, although long-term stability is high.
What is the measurement range of the MH-Z19B CO2 sensor?
The MH-Z19B sensor measures carbon dioxide concentrations in a range from 0 to 5000 ppm.
What output types does the MH-Z19B sensor offer?
It provides UART and PWM outputs to make integration with microcontrollers such as Arduino easier.
What is the sensor response time?
The T90 response time is less than 60 seconds, allowing fast and accurate readings.
Is the MH-Z19B sensor compatible with Arduino?
Yes, the sensor is compatible with Arduino boards that support UART or PWM interfaces.
What is included in the package when buying this sensor?
The package includes an MH-Z19B CO2 sensor and a cable for connection.
