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 ...

This project demonstrates the usage of a rain sensor and nRF24L01 communication module with Arduino. If you need to change pin configurations, locate the corresponding section in the Arduino code and ...

An Arduino-based smart drying stand that uses a Raindrop sensor to detect rain and a DHT11 sensor to monitor humidity. A servo motor automatically retracts the stand when it rains or humidity is high, ...

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 ...

Using an ESP8266 programmed via the Arduino IDE, [OttoNL] hooked up a light dependent resistor, a rain sensor, and the all-round workhorse BME280 for temperature, barometric pressure, and humidity ...

In the first video below, we see that as more data accumulates, the Arduino’s estimate of pi eventually converges on the well-known 3.14159 value.

Hackster.io member “t ps” has created an Internet of Things (IoT) Raspberry Pi rain checking system complete with a light sensor to provide a way of triggering other devices or code using the ...
