The P45 float switch mounts vertically inside your tank. As the water rises or falls, the float moves along its stem and switches the circuit, so your Arduino, ESP32 or controller knows exactly when the level changes.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVertical mount design with a float that slides up and down its stem\u003c\/li\u003e\n\u003cli\u003eMagnetic reed switch inside, no moving electrical contacts exposed to water\u003c\/li\u003e\n\u003cli\u003eSimple 2-wire output, works like an on\/off switch\u003c\/li\u003e\n\u003cli\u003eSwitch action can be reversed by flipping the float, for rising or falling level detection\u003c\/li\u003e\n\u003cli\u003eThreaded stem with nut for easy mounting through the tank wall or lid\u003c\/li\u003e\n\u003cli\u003eWorks with Arduino, ESP8266, ESP32, relays and water level controllers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Uses\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWater tank overflow and low-level alarms\u003c\/li\u003e\n\u003cli\u003eAutomatic water pump \/ motor control (with a relay or controller)\u003c\/li\u003e\n\u003cli\u003eAquariums, fish tanks and hydroponics\u003c\/li\u003e\n\u003cli\u003eWater dispensers, RO systems and humidifiers\u003c\/li\u003e\n\u003cli\u003eSmart home IoT and university projects\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eGood to Know\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThis is a low-power signal switch.
