About this product
Raindrop detection module combining a rain sensor board with a 12V relay module on one assembly. An LM393 comparator provides a TTL-compatible digital output with an indicator LED, so it can switch a load when rain is detected. Suited to rain-triggered projects such as window closing or irrigation control.

Frequently asked questions
What is the price of Raindrop Detection Sensor Module with 12V Relay Module in Egypt?
Raindrop Detection Sensor Module with 12V Relay Module currently costs 120 EGP in Egypt.
Where can I buy Raindrop Detection Sensor Module with 12V Relay Module in Egypt?
Raindrop Detection Sensor Module with 12V Relay Module is available from Microohm. Compare the offers above to find the best price.
How do I connect a load to the relay?
Wire the load through the relay contacts. The relay is rated 250V 10A AC or 30V 10A DC, so keep the load within those limits. Mains loads need proper insulation and enclosure.
Can a microcontroller read the rain signal?
Yes. The digital output is TTL compatible, so it can connect to a GPIO input. Check the active level of the output by observing the indicator LED when the sensor is wet and dry.
