ACEBOTT OEM Electronics Components 3.3V-5V Raindrop Vapor Sensor Steam Sensor for Arduino High Sensitivity Rainwater Sensor
Product Description
Products Description
| 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. | |
| 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. | |
| Application reference: This module can be used for car wiper, smart home and weather detection station. | |
