Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•WHAT IT IS: Raindrop sensor is a device used to detect the falling of raindrops, which is commonly used in automotive, smart home, and meteorological fields. It can sense the presence of precipitation and trigger the corresponding operation or feedback. Note：Expansion board is attached to esp32 controller board.
•HOW IT WORKS: The working principle of the raindrop sensor is to use the resistance between two electrodes to sense the landing of raindrops. When the raindrop falls to form a conductive path between the electrodes, the resistance value will change accordingly, and the sensor determines whether there is a raindrop by measuring the resistance change.
