• Wide Voltage Range: Rated for both low-voltage DC microcontroller circuits and higher-voltage AC relay applications
• 100% Authentic: Sourced directly from trusted suppliers with quality verification
• Fast 1-5 days shipping: Dispatched from our Bengaluru warehouse with same-day delivery available in Bengaluru
• Expert Technical Support: Full guidance on wiring, integration, and troubleshooting included with your purchase

How the Float Switch Works

The float switch sensor operates on a simple magnetic reed principle. A buoyant float containing a permanent magnet slides along a stem. When water rises, the float moves upward, bringing the magnet close to the reed switch contacts inside the stem, which closes (or opens) the circuit. When the water level drops, the float descends and the switch returns to its default state. This purely mechanical operation requires no external power for the sensing element, ensuring exceptional reliability and longevity.

Wiring Guide

• With Arduino/Microcontroller: Connect one wire to a digital input pin and the other to GND. Enable the internal pull-up resistor in your code (INPUT_PULLUP) or use an external 10kOhm pull-up resistor to VCC. Read HIGH/LOW to detect water level state
• With Relay Module: Wire the float switch in series with the relay coil trigger input. When water reaches the set level, the switch activates the relay, which can control a motor pump or solenoid valve
• Direct Pump Control (Low Power): For small pumps within the current rating, wire the float switch directly in series with the pump power supply for fully automatic operation without any controller
• With PLC: Connect to a digital input terminal on your PLC. Configure the input logic in your ladder program for automated industrial water level management

Project Ideas

• Automatic Water Tank Controller: Install multiple float switches at different heights in your overhead or underground tank to create a fully automated pump control system that fills when low and stops when full
• Sump Pump Automation: Place the sensor in a basement sump pit to automatically activate a drainage pump when water accumulates, preventing flooding
• IoT Water Level Monitor: Pair with an ESP8266 or ESP32 to build a WiFi-connected water level monitoring system that sends alerts to your phone via Blynk, MQTT, or Telegram
• Aquarium Auto Top-Off: Maintain consistent water levels in fish tanks and aquariums by triggering a dosing pump or solen
