Air Pressure Sensor
The MPX4115A sensor converts atmospheric pressure to an analog voltage value in a range between 0.2V and 4.8V.
This sensor is designed to sense absolute air pressure in an altimeter or barometer (BAP) application. It integrates on-chip, bipolar op-amp circuitry and thin-film resistor networks to provide a high-level analog output signal and temperature compensation.
With six pins spaced at 2.54mm, this sensor is easy to work with on breadboards.

Compatible with Waspmote This sensor can be used in a Waspmote wireless sensor platform by plugging it into the Waspmote Gases Sensor Board or the Waspmote Agriculture Sensor Board PRO. Those boards also have a voltage divider to reduce this sensor's output range to between 0.12V and 2.88V, which is safe for the low-power Waspmote system.
