Adafruit 5" eTape Liquid Level Sensor + extras

The eTape Liquid Level Sensor is a solid-state device offering a resistive output that changes with fluid levels, eliminating the need for bulky mechanical floats. Seamlessly interfacing with electronic control systems, the sensor's resistance varies inversely with liquid height.

Benefits and specifications include:

• Compact design for easy integration
• Highly accurate and affordable liquid level measurement
• Resistive output for simple microcontroller interfacing
• 5-inch version with 4-pin connector and 560Ω 5% resistor

Useful in applications such as hydroponics, aquariums, fountains, pools, and rain tube measurement, the sensor detects hydrostatic pressure changes, translating them into reliable resistance variations. Its user-friendly design includes a connector to protect delicate pins while ensuring easy soldering and setup.
