Rain Steam Sensor

The rain sensor module is a versatile and reliable tool for detecting rain and measuring rainfall intensity. Making it a must-have for weather monitoring, smart gardening, and DIY projects. It features a separate rain board and control board for flexible installation. Along with a power indicator LED and an adjustable sensitivity potentiometer for precise calibration. The module offers both analog and digital outputs, thanks to the onboard LM393 comparator. Making it compatible with a wide range of microcontrollers, including Arduino and Raspberry Pi.

When powered with 5V, the module’s LED lights up when the rain board is dry, and the digital output (DO) remains high. Once water droplets hit the sensor’s exposed copper traces, the DO output switches to low, turning on the indicator LED. The sensor quickly resets to its initial state once the water evaporates or is wiped off, ensuring reliable performance in varying weather conditions. This makes it ideal not just for rain detection, but also for monitoring water levels, like checking if a water tank is overflowing.

Whether you’re building a smart irrigation system, a weather station, or just need a reliable way to detect moisture, this rain sensor module is an affordable, easy-to-use solution that will enhance your project.
