The MS5839 digital altimeter measures only 3.3 x 3.3 x 2.75 mm. It is optimized for applications where chlorine and saline are present. The gel-filled MS5839 design allows it to work in harsh environments while providing accurate and reliable measurements.
The MEMS-based sensor provides water resistance, chlorine resistance, shielding, low power consumption and digital interconnectivity in a low profile package. It has a sensing accuracy of ±0.5mbar for pressure and ±2°C for temperature measurements.
