MO4 Water Level Sensor
$0.471pcs
The MO4 Water Level Sensor is a non-contact liquid level switch that operates on a capacitive principle to detect the presence or absence of liquid. It is designed to be mounted on the outer wall of a container to detect the liquid level within.

Operation:
When the sensor detects the presence of liquid, it will output a low level signal.
When no liquid is detected, the sensor will output a high level signal.
Applications
- Liquid level monitoring in pipelines
- Overflow prevention in containers
- Industrial liquid level sensing
- Non-contact liquid level detection in household appliances
Schematic
Mounted on a container’s outer wall, the sensor’s surface forms an equivalent capacitor with the external medium (e.g., air or liquid). As liquid nears, the dielectric constant rises, increasing the capacitance. The chip converts this capacitance change into a voltage, which an internal comparator then measures against a set threshold. Based on this, it outputs a high or low signal to indicate whether water is present.
