    FAQ:
    1. Question: If the M04 input is 12V, how do I connect the pull-up resistor? Answer: Depending on the connected device, pull it up to 5V or 3.3V if connected to a microcontroller port. The voltage can be adjusted according to the device's specifications.
    2. Question: Can it be connected to a microcontroller or Arduino? Answer: Yes, the open-drain output allows for connection to PLCs, microcontrollers, or other equipment. M03 can be directly connected to an Arduino microcontroller, while M04 requires a pull-up resistor for open-drain output.
    3. Question: What is the working principle? Answer: Liquid output is low level when detected by the inductor and high level when not detected.
    4. Question: Can I buy the chip alone? Answer: Yes, the chip is available for purchase separately.

    Enhance your liquid level detection applications with the reliable and versatile M03/M04 Non-Contact Liquid Level Detection Module Sensor, offering precise sensing and easy integration into your projects without the need for direct contact.
