Skip to the content Rain and snow sensors allow you to automate controls in response to detected moisture. This is particularly useful for automatic heating controls latching when snow or ice are present. They may also be used to shut off automated sprinkler systems when there is rain.
The Comptus A70H-RS is an affordable device with a 2 inch diameter surface that detects moisture from rain or snow and latches a NO (Normally Open) relay.

Meet the A70H-RS – our compact, cost-effective rain and snow sensor, engineered for precision. With its 2″ diameter moisture-sensing plate, the A70H-RS monitors rain or snow and triggers a normally-open (NO) relay when precipitation is detected. Ideal for automated control of heating systems, sprinklers or other critical environmental systems.

Yes, absolutely. Many modern rain and snow sensors are designed to detect both types of precipitation. These dual-purpose sensors work year-round, monitoring rain in summer and snow or ice in winter.
Rain and snow gauges collect and measure precipitation over time. Rain is measured directly, while snow is typically melted before measuring its water equivalent. This gives you accurate data on how much precipitation your area receives.
Placement matters a lot! Install your gauge in an open area away from trees, walls, or roofs that might block or redirect rain or snow. Make sure it’s level and secure to get the most accurate readings especially important for snowy or windy locations.
Most sensors connect directly to your irrigation or building-management system using a simple relay or switch output. When the sensor detects rain or snow, it sends a signal to start or stop certain functions like pausing irrigation or turning on heating systems.
That depends on the model and its settings. Some rain and snow sensors trigger after detecting just a light drizzle or trace of snow, while others can be adjusted to activate only during heavier precipitation.
Usually not. Most rain and snow sensors and gauges today handle both, but make sure the one you choose is rated for freezing conditions if you’ll be using it in snowy climates.
Very little! Just keep the sensor clean and free of debris, ice, or dirt. Check connections and ensure the surface is clear for accurate detection. For gauges, make sure they’re not blocked by snow or leaves and remain level throughout the year.
That’s a common question. Wind, snow density, and drifting can cause snow gauges to collect less than what you see visually. It doesn’t mean your gauge is broken, it's just how snow behaves. Using wind shields or specialized snow gauges can improve accuracy.
Yes! Many industries and researchers rely on rain and snow gauges for tracking precipitation trends, studying climate, or managing water resources. Just make sure your gauge meets the accuracy requirements for your application.
