Sensors / Barometric Pressure
We carry a variety of sensors to measure barometric air pressure, useful when you want to know about the weather or to determine altitude. The air thins out the higher we get above sea level. As we travel from below sea level to a high mountain, the air pressure decreases. That means that if we measure the pressure we can determine our altitude - handy when we don't want the expense or size of a GPS unit.
Weather can also be estimated with barometric pressure - low pressure means a storm is heading our way. For accessibility uses, these can also be used as sip/puff detectors. And of course, pressure sensors can also be used to measure air pressure inside a sealed container.
Most of our barometric pressure sensors also have temperature sensing built in, some have humidity sensing as well. Most of the sensors we have are for ambient pressure sensing, but we also stock some sensors with ports that can be used to attach a tube.

We stock a few barometric pressure sensors, great for altitude and weather measurements. This pressure sensor is special because it comes with a metal port! Unlike other pressure sensors, you can easily attach a tube to it, to measure air pressure inside a close space. In particular we think this would be a great sensor for use with making DIY assistive tech "Sip & Puff" interfaces, or measuring the pressure within a vacuum chamber...

We live on a planet with an atmosphere, a big ocean of gaseous air that keeps everything alive - and that atmosphere is constantly bouncing off of us, exerting air pressure on everything around us. But, how much air is in the atmosphere, bearing down on us? This absolute pressure sensor, ST LPS25HB can quickly and easily measure this air pressure, useful when you want to know about the weather (are we in a low pressure or high...

How high are you right now? If you had a precision altitude sensor, you would know for sure! The DPS310 sensor from Infineon a high precision barometric sensor, perfect for measuring altitude changes with a up to ±0.002 hPa (or ±0.02 m) precision high precision mode and ± 1 hPa absolute accuracy. That means you can know your absolute altitude with 1 meter accuracy when you set the sea-level pressure, and measure changes in...

Bosch has been a leader in barometric pressure sensors, from the BMP085. BMP180, and BMP280... now we've got the next generation, the Adafruit BMP388 Precision Barometric Pressure sensor . As you would expect, this sensor is similar to its earlier versions but even better . The BMP388 has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter . It can even be used in either I2C and SPI...

This pressure sensor from Freescale is a great low-cost sensing solution for precision measurement of barometric pressure and altitude. The MPL3115A2 has a typical 1.5 Pascal resolution, which can resolve altitude at 0.3 meters (compare to the BMP180 which can do 0.17m). It has some upsides compared to the BMP280, such as interrupt outputs for ultra-low power usage, and its also a heck of a lot easier to read altitude with a built in altimeter...

This pressure sensor from Freescale is a great low-cost sensing solution for measuring barometric pressure. At 1.5 hPa resolution, it's not as precise as our favorite pressure sensor, the BMx280 series, which has up to 0.03 hPa resolution so we don't suggest it as a precision altimeter. However, it's great for basic barometric pressure sensing. The sensor is soldered onto a PCB with 10K pull-up resistors on the I2C pins. This chip is...

Sometimes you need to sense pressure in a damp or caustic environment. And sometimes you need to know the relative changes in pressure as well as the absolute pressure. For the times you need to do both (or either), the LPS33HW is the pressure sensor for you. Combining protection from water intrusion with support for high precision relative and absolute measurements, this sensor will do what you need. With drivers for CircuitPython, Arduino, and...
