If you leave the sensor powered on, electrolysis will eventually destroy the nickel coating on the sensing pad (water + electricity + metal = corrosion). Usaha Ayam Petelur Doc Updated: Contoh Proposal
But if you’ve ever tried to read the official "datasheet" (often a folded piece of paper with broken English), you know it leaves a lot to the imagination. It tells you the voltage is 5V and the output is Digital or Analog, but it doesn't tell you why your readings are fluctuating or why the sensor seems to "forget" it’s raining after ten minutes.

The grid pattern consists of interlaced traces that are not connected. When dry, the resistance between them is near-infinite (open circuit). When raindrops bridge the gap, the water acts as a conductor, lowering the resistance significantly.
Long wires create resistance. If your control board is far from your MCU, the analog signal can degrade. The "Better Datasheet" fix? Place the Control Board near the sensor , and run long wires for power and digital signals, OR use a capacitor (100uF) across the VCC/GND rails near the sensor to smooth out the power supply.
If you’ve ever built a weather station, an automatic window opener, or a smart irrigation system, you’ve likely stumbled across the YL-105 Rain Sensor Module . It’s cheap, ubiquitous, and incredibly useful.
