{"title":"12 eTape Liquid Level Sensor + extras","handle":"12-etape-liquid-level-sensor-extras","url":"/products/12-etape-liquid-level-sensor-extras","description":"The eTape Liquid Level Sensor is a solid-state resistive sensor that measures fluid level without mechanical floats. As the liquid level rises, the hydrostatic pressure compresses the sensor envelope, decreasing its resistance. The output is inversely proportional to the liquid height — lower liquid means higher resistance, higher liquid means lower resistance.\n\nThe sensor is resistive, so it can be read directly from a microcontroller or Arduino ADC pin with a simple voltage divider circuit. A 4-pin connector and 560Ω resistor are included so you don't need to solder directly to the delicate sensor pins.\n\nKey Features\n\n\nSolid-State Design – No mechanical floats or moving parts\n\nResistive Output – Easy to read with any ADC or microcontroller\n\n12\" Sensing Length – Suitable for tanks and containers up to 30cm deep\n\nIncludes Connector & Resistor – 4-pin connector and 560Ω resistor included\n\n\nIdeal For\n\nHydroponics and aquaponics systems\nAquarium and fountain level monitoring\nRain gauge and weather station projects\nPool and water tank controllers\nArduino and microcontroller liquid-level projects\n\n\nPackage Contents\n\n1× 12\" eTape Liquid Level Sensor\n1× 4-pin connector\n1× 560Ω resistor\n\n\n\nTip: For chemical, petroleum, or food-safe applications, see the Chemical eTape version with Teflon jacket.\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":12448,"title":"Default Title","sku":"AF-464","price":85.78,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
