Wireless Rain Gauge

A wireless rain gauge is a type of an electronic device that is used in the measurement and recording of rainfall on a daily basis. The rainfall that is taken into a rain collector is measured by the gauge and the results are transferred to a display panel wirelessly. Therefore, a wireless rain gauge always consists of two units, one indoor and the other outdoor. The outdoor unit is the rain collector and the indoor unit is the one that obtains data from the collector. There are several places where this device can be of good use, including weather stations, gardeners and sometimes in homes, just to have some fun with measuring the rain.

In older times a rain gauge was a cylindrical, graduated instrument that involved the observer walking out in the rain to manually take measurements. This is also called a standard gauge. Keeping this in mind, the wireless rain gauge has two main advantages over traditional ones. The first is due to the display panel which is an indoor unit, rainfall can be measured without having to go outside and get wet in the rain. Second, most wireless rain gauges come with rain collectors that have a self-emptying feature. Hence, the additional task of emptying the container each time before rainfall or after the experiment, is eliminated.

Extra features are also available with wireless rain gauges. Some models can act as barometers, while some others come with a thermometer for outdoor temperature measurement. The range of coverage provided commonly is in between 100 to 350 foot. More advanced models or versions of this product may offer higher range and are also able to detect and measure wind speed, wind chill, wind direction, humidity and dew point. These wireless rain gauges also include settings such as a clock and calendar. If needed, connection to a PC is also one of the available features. These instruments not only act on measuring the rainfall but also in providing a complete weather forecast. Wireless rain gauges are also sometimes programmable so that upon detection of rain, an alarm can be sounded off. There are electronic rain gauges that are wired, with wires connecting the collector to the display unit. By using a wireless rain gauge, all these wires can be eliminated and it is much easier to install.

Most of the wireless rain gauge models available are battery operated. Certain brands offer solar powered rain gauges as well. The regular battery operated models run on inexpensive 4-AA batteries. This may vary, however, depending on the make and design. In general, rainfall records can be stored for up to 9 days on a standard wireless rain gauge. A majority of rain gauges have rain collectors that are designed with a funnel that tapers down into a cylinder where measurement of rain takes place. On an average, the price of a wireless rain gauge for home users may begin anywhere around $ 20 to $35 and rise with the number of features that are incorporated.

The data accumulated by using a rain gauge is useful to a variety of people such as atmospheric scientists and meteorologists. Some people who are weather forecast enthusiasts take up rainfall measurement as a hobby. Incidentally, the earliest instance of use of a standardized rain gauge is believed to be by a Prince in Korea in the 1400s. Prince Munjong is credited with the invention of the device and it was put to use by the King Sejong, his father. The main purpose for its use was the collection of taxes. Depending upon the amount of rainfall received by each village, taxes were accordingly determined.
