M04 Non-contact Water Level Detection Module
The M04 Non-contact Water Level Detection Module represents a significant advancement in sensor technology, offering a reliable solution for detecting liquid levels in a variety of containers without the need for direct contact. This module utilizes an inductive sensing principle, where it detects changes in the electromagnetic field caused by the presence of liquid near the sensor. When no liquid is present, the output remains at a high level; upon detection of liquid, it switches to a low level, providing a clear digital signal for easy interpretation by microcontrollers or other control systems.
Features:
- Utilizes inductive sensing for non-contact liquid level detection.
- Supports a wide supply voltage range from 3.3V to 26V (recommended maximum 24V).
- Provides open-drain output that is high when no liquid is detected and low when liquid is present.
- Offers a sensing distance of 3 to 4.5mm through non-metallic container walls.
- Operates reliably in temperatures from -40°C to 85°C.
