Frequently Asked Questions

What is the output interface of the ZE08B-CH2O module?

The module provides dual outputs: a digital UART interface operating at 3V logic levels for direct communication with microcontrollers, and a linear analog voltage output proportional to the formaldehyde concentration. This allows for flexible integration into both digital and analog measurement systems.

What is the recommended operating voltage and how do I power it?

The module requires a DC power supply between 3.7V and 5.5V. It can be powered directly from a regulated 3.3V or 5V microcontroller rail, or via a dedicated LDO regulator. Ensure the power source is stable and free from noise for optimal sensor performance.

How fast does the sensor respond and how long does it take to warm up?

The sensor has a warm-up (start-up) time of 3 minutes or less from a cold start. Once warmed up, it achieves 90% of its final reading (T90) within 60 seconds of exposure to a target gas concentration, and recovers to baseline within a similar timeframe.

What is the sensor's lifespan and does it require calibration?

The electrochemical sensor element has a typical operational life of 2 years when exposed continuously to air. For accurate measurements, periodic calibration using a known formaldehyde standard is recommended, especially after extended use or exposure to high concentrations.
