Rain Drop Sensor acts as a switch when raindrops fall to the sensor, other than that with slight tweaks in the code it can also measure the intensity of the rainfall. We Interfaced the Rain sensor ...

Ultrasonic Distance Sensor with LED and Piezo Speaker This project uses an ultrasonic distance sensor to measure the distance to an object and controls three LEDs (Green, Yellow, and Red) based on the ...

In this project we are going to build a rain detector project using arduino and rain drop sensor.

This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...

A novel low-cost rain sensor based on a Surface Plasmonic Resonance (SPR) platform has been designed, realized, and tested. The SPR platform has been used to detect the presence of rain by using a ...

Shifting to the new waterproof ultrasonic sensor is not a big deal, since it’s pretty easy to modify some example codes to use it. The quick road test, oh it’s a simple approach to display the ...

Arduino UNO circuit board [8] and an HC-SR04 ultrasonic distance sensor [9] were used for data collection and are shown in Figure 2. Arduino UNO was placed on upper face of top plate and ultrasonic ...
