About this item

The MPL3115A2 is a compact and low-power I²C sensor that measures barometric pressure, altitude, and temperature. Operating within a voltage range of 3.0V to 5.5V, it offers high-resolution data with a pressure sensing range of 50–110 kPa and an altitude resolution of 1.5 Pa (approximately 0.3 meters). The sensor provides 20-bit pressure and altitude measurements, along with 12-bit temperature readings. Its small form factor (18mm x 19mm x 2mm) and low power consumption make it ideal for portable applications such as weather stations, drones, and environmental monitoring systems. The MPL3115A2 is compatible with various microcontrollers, including Arduino and Raspberry Pi, and is widely available from electronics distributors.
