Anti-Corrosion Rated Water Level Sensor with Ball Float Switch
Anti-Corrosion Rated Water Level Sensor with Ball Float Switch
This water level sensor uses a ball float switch mechanism to detect liquid levels. Designed with corrosion-resistant contacts, it is ideal for water tanks, sumps, and industrial liquid containers. It provides reliable on/off switching for automatic pump control or level alarms.

Compatibility
This float switch works with any microcontroller including Arduino, ESP8266, ESP32, and Raspberry Pi. Use a digital input pin with internal pull-up to detect the switch state. It is compatible with both 5V and 3.3V logic boards when configured correctly.
Wiring Notes
Connect one wire to a digital I/O pin with an internal pull-up resistor enabled, and the other to ground. When liquid level rises, the internal reed switch closes, pulling the pin low. Avoid switching high inductive loads directly; use a relay module for pump control.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, connect the float switch to any digital pin with internal pull-up enabled. It acts as a simple switch, giving a HIGH/LOW signal for water level detection.
How does the anti-corrosion feature work?
The anti-corrosion rating comes from the sealed reed switch and corrosion-resistant PP plastic body, preventing rust and ensuring long life in water.
What is the maximum current this switch can handle?
The switch can handle up to 0.5A of current. For higher loads, use a relay to control the pump or device.
