M04 Non-contact Water Level Detection Module

The M04 water level detection sensor is a non-contact sensor and by using inductance, low output power with liquid and high output power without liquid can be achieved. The detection distance is usually 3-4.5mm.

Note:
The output is open-drain and can be connected to some PLC or other devices or drive equipment directly. The M04 sensor needs to pull a resistor. The open drain output has high resistance and low level only.

Interface Structures:

1. Gnd: power supply-power source ov
2. Vcc: power supply + power supply 3.3-26V
3. Output: high-level non-inductive power output with low-level inductive output

M04 Water Level Detection Application:

1. Water reservoir
2. Garden and irrigation
3. aquarium
4. Ice machines
5. Fish tanks

M04 Water Level Detection Specifications:

1. Operating temperature: -40 to 85 degrees
2. Supply voltage: 3.3-26V (recommended no more than 24V)
