Description

This pressure from Freescale sensor is a solution at low prices for Grand barometric pressure. With a resolution of 1, 5hPa, it is not as accurate as the BMP085 pressure sensor which has a precision of 0.03 hPa, so that is why we do not offer it to measure altitude. On the other hand, it's good enough for basic measures of barometric pressure. The sensor is welded on a PCB with a resistance of 10 kΩ pullup.

This tour offers of an eplage of power between 2, 4V and 5, 5V, which is that it can be used with a 5V logic or 3V3. The dialogue is carried out through an I2C link.
