SparkFun Barometric Pressure Sensor - MPL115A1 SMD ICs Turn Signal Assemblies & Lenses They can also be used

They can also be used for a very small audio transducer such as a buzzer

but the SMD module prohibits immediate gratification

It’s a great board that will get you up and running quickly

Both the transmitter and receiver work at common frequencies and don’t have IDs

Stops light coming into the lens at extreme angles and being reflected inside the lens

SparkFun Barometric Pressure Sensor - MPL115A1 SMD ICs Turn Signal Assemblies & Lenses They can also be usedThe MPL115A1 is a digital barometer that uses MEMs technology to give accurate pressure measurements between 50kPa and 115kPa. We stock the SPI interface version of the sensor. Average current consumption is 10A at one measurement per second. The sensor outputs both temperature and pressure readings on the SPI bus. See page 3 of the datasheet for information on how to take readings from the pressure sensor. Breakout board coming soon! Features: Wide
