It outputs an NPN signal (low when liquid detected) suitable for microcontrollers and control circuits. Ideal for water tanks, pipelines, and automatic water level control systems.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e5-24V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eNPN (active low)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensing Distance\u003c\/td\u003e\n\u003ctd\u003eUp to 13mm through non-metal wall\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;100ms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;5mA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20°C to 80°C\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-water-level-indicator\"\u003eWater level indicator with LED or LCD display\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eAutomatic water pump controller for overhead tanks\u003c\/li\u003e\n  \u003cli\u003eTank overflow alarm with buzzer and relay\u003c\/li\u003e\n  \u003cli\u003ePipe burst detection by monitoring flow at multiple points\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks with 3.3V and 5V logic microcontrollers like Arduino, ESP8266, ESP32, Raspberry Pi (with voltage divider).

Add a 10kΩ pull-up resistor from yellow wire to VCC if microcontroller internal pull-up is insufficient. Ensure sensor face is tightly attached to the non-metal container wall.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
