An Arduino Uno raindrop sensor detects rain or moisture by measuring the conductivity between its probes. It's often used in weather monitoring systems and automated irrigation systems for detecting ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Connections are pretty simple and only a few wires. Connect the VCC and GND of the sensor to the 5V and GND pins of the Arduino. Then connect the output to the Arduino’s D2 pin. Here's how the ...

The Arduino Mega interfaces with a raindrop sensor module to detect rain or water presence, useful for weather monitoring, irrigation systems, and rain detection alarms in various electronic projects.
