The new weather sensor can be attached to the umbrella. It works in real time

The development is a lightweight touch sheet, which is equipped with a flexible resistive sensor and

reservoir. To determine the amount of precipitation, the device measures the electrical resistance that occurs when a raindrop hits its surface.

The device is coated on top with a superhydrophobicpolydimethylsiloxane (PDMS) silicone sheet, which is impregnated with graphene and additionally processed by a laser. Due to this, water droplets are repelled from the sensor, which ensures its durability and stability. Laser texturing allows you to constantly monitor and measure the behavior of water droplets, whether they remain, glide, bounce or split on the sensor surface.

The study showed that placing the sensor underdifferent angles, does not affect the reliability of the results obtained. Therefore, the sensor can be easily attached to a wide variety of objects such as an umbrella, car or house.

Although there is still much to be doneto improve the accuracy of the device, it is expected that the sensor will become the basis for the next generation of weather detection. Scientists believe that if this technology is widely adopted, it would be possible to obtain massive data that will allow the development of local weather maps in real time.

Disaster reports are coming in all overthe world, and one of the sources of serious damage to cities are floods caused by localized heavy rains. Sharing local weather information can save lives. However, real-time local weather information is difficult to collect because such data collection requires bulky and expensive sensors. The development, as the researchers hope, will help solve this problem.
