MPL3115A2 - I2C Barometric Pressure/Altitude/Temperature Sensor
We have ✅ 1 available of the AF-1893 in our Sydney warehouse. An extra 100 units available with a short lead time.
The MPL3115A2 is a precision barometric pressure, altitude, and temperature sensor from NXP (formerly Freescale) that communicates over I2C. With 1.5 Pa resolution, it can resolve altitude changes as small as 0.3 m and includes a built-in altimeter calculation — no external calibration or manual computation required.
This breakout includes an onboard 3 V regulator and logic level shifting, so it works directly with 5 V microcontrollers like Arduino as well as 3.3 V boards. The sensor also features interrupt outputs for ultra-low-power applications, and a built-in temperature sensor with ±1 °C typical accuracy.
