Frequently Asked Questions

What are the output options of the ZE08-CH2O module?

The module provides three simultaneous output options: a digital UART (serial) interface for direct communication with microcontrollers like Arduino or Raspberry Pi, an analog voltage output (typically 0-3V corresponding to 0-5ppm), and a PWM (Pulse Width Modulation) wave output. This flexibility allows integration into both digital and analog control systems.

What is the recommended power supply voltage for this module?

The module operates from a wide DC voltage range of 3.7V to 9V. This makes it compatible with single-cell Li-ion batteries (3.7V), 5V USB power, or regulated 9V power adapters, offering significant flexibility for portable and fixed installations.

Does the sensor require calibration, and how is temperature compensation handled?

The sensor is factory calibrated for formaldehyde detection. It features a built-in temperature sensor that automatically performs real-time temperature compensation within its 0°C to 50°C operating range, ensuring measurement accuracy is maintained despite ambient temperature fluctuations.

How do I interface the UART output with an Arduino or ESP32?

Connect the module's TX pin to the microcontroller's RX pin and the RX pin to the microcontroller's TX pin, ensuring a common ground. Use a logic level converter if your microcontroller operates at 3.3V. The module communicates via a standard serial protocol; you will need to refer to the Winsen datasheet for the specific command set to request concentration data.
