AVT3029 A

We present an unusual, capacitive liquid sensor. It requires few elements and can be used, for example, to control the pump. It is a device that directly monitors the minimum liquid level in the tank. The capacitive element was used as the sensor.

The device is especially recommended for monitoring the liquid level (aquarium, potable water tank etc.)

Selected parameters:

• capacitive sensor - paths on the printed circuit board
• high resistance to external interference
• configurable OC type output at the assembly stage
• layout designed on a single integrated circuit series 4000
• additional liquid level signaling - LED diodes
• power supply - 12-24Vdc
• printed circuit board and documentation included
