This sensor measures atmospheric barometric pressure. This sensor has five common ranges for displaying atmospheric pressure: kPa - Kilo Pascal Atm - Atmospheres in. Hg - Inches of Mercury mm Hg - Millimeters of Mercury The fifth range is the altitude (in meters). The highest barometric pressure is on the sea level - when we go up, the pressure goes down. *Requires connection hardware, sold separately. Experiment Duration: 1 second to 31 days. Operation Modes: Range | ADC Resolution | Resolution | Max Sample Rate (S/sec): 80 - 106 kPa, 10 bit, 0.1 kPa, 100 0.80 - 1.00 Atm, 10 bit, 0.01 Atm, 100 23.60 - 31.30 in/Hg, 10 bit, 0.01 in/Hg, 100 -380 - 1950 m, 10 bit, 0.1 m, 100
