{"id":130,"count":3,"description":"<p>The <strong>rain gauges and rain sensors<\/strong> These are meteorological instruments used to measure the <strong>atmospheric precipitation<\/strong> and record the amount of rainfall over a specific time interval. These devices are essential in automatic weather stations, precision agriculture, hydrological monitoring, and climate studies.<\/p>\r\n\r\n<p>Precipitation is normally expressed in <strong>millimeters (mm)<\/strong>, a unit equivalent to liters per square meter (l\/m\u00b2). The rain gauge collects rainwater using a funnel of known area and directs it towards a calibrated measuring system, allowing for the precise determination of accumulated precipitation.<\/p>\r\n\r\n<h2>Rainfall measurement technologies<\/h2>\r\n\r\n<ul>\r\n<li><strong>Tilting bucket rain gauges:<\/strong> The most widely used technology in automatic weather stations.
