Not recommended for new design-ins
The BMP180 is the new digital barometric pressure sensor of Bosch Sensortec, with a very high performance, which enables applications in advanced mobile devices, such as smartphones, tablet PCs and sports devices. It follows the BMP085 and brings many improvements, like the smaller size and the expansion of digital interfaces.
The ultra-low power consumption down to 3 μA makes the BMP180 the leader in power saving for your mobile devices. BMP180 is also distinguished by its very stable behavior (performance) with regard to the independency of the supply voltage.
- Indoor navigation
- GPS-enhancement for dead-reckoning, slope detection, etc.
- Sport devices, e.g. altitude profile
- Weather forecast
- Vertical velocity indication (rise/sink speed)
A wristband personal alarm clock will make sure that not only will you get up on time but also in sync with your natural biorhythm. A smartwatch can improve your health by detecting poor air quality in your environment. Smart fitness wear can improve the efficiency of your workout by measuring your speed and calorie consumption. What do all these wearable applications have in common? They are made possible by the almost invisible MEMS sensors and clever sensor solutions.
BMP280 is a barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact package. Its small dimensions and its low power consumption allow the implementation in battery powered devices such as mobile phones, GPS modules or watches.
The BMP380 is a very small, low-power and low-noise 24 bit absolute barometric pressure sensor. BMP380 is specifically designed and ideally suited for a wide range of altitude tracking applications.
The BME680 integrates sensors for gas, pressure, humidity and temperature. The integrated gas sensor within the BME680 can detect a broad range of gases to measure indoor air quality for personal well being. It comes in a metal-lid 3 x 3. x 0.95 mm³ LGA package.
The BME280 is an integrated environmental sensor developed specifically for mobile applications. The unit combines sensors for pressure, humidity and temperature in an metal-lid 2.5 x 2.5 x 0.93 mm³ LGA package.
