Frequently Asked Questions

What is the supply voltage requirement for the ZE630 module?

The module requires a stable 5V DC power supply with a tolerance of ±0.5V. It is designed for direct compatibility with standard 5V logic systems, including many microcontroller development boards and automotive control units. Ensure your power source can provide adequate current for the sensor's pre-heating and continuous operation phases.

How do I interface with the ZE630 sensor module?

The ZE630 provides two digital output options: UART (serial communication) and PWM (pulse-width modulation). You can select the desired interface via configuration. The UART output provides direct digital concentration data, while the PWM signal's duty cycle corresponds to the gas concentration, allowing simple reading with a microcontroller's digital input pin.

What is the module's response time and start-up procedure?

The sensor requires an initial 3-minute pre-heating period after power-on to stabilize its electrochemical element. After this, it achieves a T90 response time of less than 40 seconds to changes in hydrogen concentration. For accurate initial readings, allow the full pre-heat cycle to complete before taking measurements.
