Sensors with C++ sensor library?

[artiny]

Hy,
I would like to buy sensors,which are avaible C++ library....could someone me add advice, who is used before some sensors with c++ library and was easy to use it

I need (not integrated for exl. accelero+gyro, or temperature+barometer.......I need it separately):
-accelerometer
-gyroscope
-analog temperature sensor
-barometer
-gps modul

THANK YOU

hello,
I am using some of the sensors you mentioned by myself, maybe you wish to look here:

CMPS11: 9D IMU == 3D Gyro + 3D Compass + 3D Accelerometer (by I2C):

as a GPS I have the GY-NEO-6M V2 (by UART) - I have no Raspberry USB/UART code (I use it on Arduino), but I was told it would work:

about Analog sensors:
The Raspi has no ADC port, so you'd need a multi-IO Board or an i2c-to-ADC multiplexer chip like the PCF8591 for interfacing:

Notice that for HATs perhaps no C/C++ drivers exist.


HTH!

For temperature measurement I use the HTU21D ... it is a combined temperature/humidity sensor with I2C interface...:

Sparkfun HTU21D breakout board

It has the advantage that there is a hwmon kernel driver for it ... so the measurements are available via the sysfs interface, and also via lm-sensors

There is also the Microchip MCP9808 (also I2C)... this has no kernel driver, but a c driver and python bindings are existing here:

You might also give the DS1820 a try, which is a OneWire temperature sensor - kernel driver is existing.


For GPS I can also recommend the NEO-6M ... I once got this working on a Pi with the gps daemon (gpsd) which is a really nice piece of software... instructions are here:
