Electronics enthusiasts and makers, these water level sensors are fantastic for all kinds of Arduino and DIY projects! This 20-piece pack gives you plenty to experiment with for multiple projects or replacements. The sensor works by measuring water droplets and levels through exposed parallel wire traces - basically, the more water contact, the higher the analog signal output.
Operating at DC 3-5V with less than 20mA current draw, these sensors are energy-efficient and easy to power with most development boards. The detection area measures 40x16mm, and the overall module size is 62x20x8.1mm - compact enough for various applications. The FR4 double-sided construction with tin spraying and electronic components ensures reliability and durability.
What's really cool is how versatile these sensors are. You can use them for water level alarms in tanks, rain detection systems, weather stations, plant watering automation, or any project where liquid presence or level needs monitoring. The analog output makes integration straightforward with Arduino, Raspberry Pi, or other microcontrollers. The working range of 10-30°C and 10-90% humidity means they perform well in most indoor environments. Whether you're a student learning about sensors, a hobbyist building smart home projects, or a professional creating monitoring systems, these water level detectors provide reliable performance at an affordable price point. Your electronics projects just got smarter with liquid detection capabilities!
