The precipitation is a meteorological variable of extreme importance. The variable is directly associated with the water supply reservoir, energy production and is responsible for flooding and soil erosion processes (SOUSA, 1998). In the agriculture, particularly, the knowledge of the rainfall regime stands out as a analysis tool and decision-making. Pluviograph and pluviometers are used to quantify rainfall. Through these two instruments it is possible to measure the rainfall amount and intensity. Therefore, with this data it is possible to local forecasting model and analysis systems. Thus, the accurate knowledge of precipitation time series is an essential tool future behavior modeling. In this work, a review of the main sensors employed to measure precipitation and the practical difficulties encountered by researchers when using rainfall data and sensor calibration. For this, a research in the Google academic was filtering the works associated with the subject. The results allowed to conclude that any rain gauge can be used, provided that it is properly calibrated.
