The sb-100 is a cost-effective and economical atmospheric pressure sensor with high accuracy and good stability. The accuracy is 1.5% in the range of 15~115kPa. Multiple sensors were used to test the stability model indoors and under natural conditions, with annual data drift of less than 0.5%. When the temperature is in the range of -20~50℃, the influence of temperature change on the sensor signal is less than 1%. With low power consumption and high signal, the power consumption of sb-100 is about 35mW, the voltage output is in the range of 0~5V DC, and the pressure measurement is in the range of 15~115Kpa.
