Measuring the absolute pressure of the enviroment using a digital barometer such as this has some interesting applications. By converting the pressure measured into altitude, you have a reliable sensor for determining the height of your robot, plane or projectile!
Using a sensor as capable as the GY-68 you can achieve accurary of 1m, with noise of only 17cm in ultra high resolution noise. The device will operate at only 0.3uA meaning low current draw for battery powered applications.
The GY-68 comes fully calibrated and ready to use. As the device operates over I2C we've added optional I2C pull ups that can be enabled using the PU (pull up) jumper on the board for your convenience and ease during breadboarding.
Using I2C, the device provides pressure and temperature as 16bit values, which are used along with calibration data within the device are used to provide a temperature compensated altitude calculation.
Caratteristiche:
Tensione di alimentazione da 1,8 V a 3,6 V.
Low power consumption - 0,5uA at 1Hz
Interfaccia I2C
Max I2C Speed: 3,5 Mhz
Very low noise - up to 0,02hPa (17 cm)
Full calibrated
Gamma di pressione: 300hPa to 1100hPa (+9000m to -500m)
La confezione include:
1 x GY-68 Digital Barometric Pressure Sensor Module

Montati su arduino nano per un mio progetto di controllo pressione turbo. Inserendo questo sensore ho potuto compensare la pressione atmosferica in tempo reale e avere su display anche altezza e temperatura!

Item arrived well packaged and on time. No problems with supplier or product. The barometer works well with the Arduino libraries and I've been running the test code for a few days now without problems. Seems to be fairly accurate - good enough for a simple weather station.

This is a 3.3V unit. I suspect I blew mine by using 5V.As such I can`t comment on the unit.

Useful sensor that can be used as an altimeter or barometer. Accurate temperature measurement is also provided . These are relatively easy to interface to the Arduino with library and examples available. The modules uses the IC2 communication protocol and is well supported by the Arduino.

Found a tutorial on raspberry-spy and had it working in 20 mins. Pressure value agrees with my barometer in the hall at least!
