The raindrop sensor is an analog-type sensor that effectively measures changes in resistance when it encounters water. This property makes it an ideal choice for detecting rain and water presence in ...

Create a circuit diagram showing the connections between the DHT11 sensor, Raindrop sensor, microcontroller, and alert mechanisms. Design the physical casing to ensure the device is compact, ...

The Internet of Things technology and sensor technology can be used to analyze and process the rainy day data, and the raindrop detector based on Arduino is built. Arduino is a convenient, flexible ...

The advent of smart drying racks, as an intelligent device, has seen a gradual rise in consumer favour due to the ongoing development of smart home technology. This paper proposes an intelligent ...

The raindrop sensor detects the presence of rain by measuring the conductivity of water droplets on its surface. The setup involves connecting the sensors to the Raspberry Pi’s GPIO pins.
