Non-contact Capacitive Liquid Level Sensor
We have ✅ 1 available of the DF-SEN0368 in our Sydney warehouse. An extra 320 units available with a short lead time.
A non-contact capacitive liquid level sensor that detects whether liquid is present inside a non-metallic container or pipe without direct contact with the fluid. It works by measuring changes in capacitance through the container wall, making it suitable for corrosive liquids, strong acids, alkalis, and high-temperature fluids including boiling water.
The sensor includes adjustable sensitivity, a status indicator LED, and a 4-pin adapter for direct digital signal output to Arduino or other microcontrollers. It can penetrate non-metallic materials (plastic, glass, ceramic) up to 20 mm thick.
