Hello
I just bought this sensor.
http://www.dealextreme.com/p/arduino-hdpm01-electronic-barometer-w-compass-module-high-sensor-module-141365

But I cant find the liberies to make it work. Anyone know where I can find them.

Thanks

Datasheet appears to be here: http://www.hoperf.com/upload/sensor/HDPM01.pdf - seems to be I2C

Thanks.

I finaly I have found a working library: HP03 pressure sensor library update - Sensors - Arduino Forum

The problem it is not compatible with the version 1.0.1 of arduino.

The changes are probably relatively easy:

  • Change "WProgram.h" to "Arduino.h"
  • Change every call of "Wire.send()" to "Wire.write()"
  • Change every call of "Wire.receive()" to "Wire.read()"

Then test it.

Thanks pylon

Now it is working, I had to change as well, the byte type for uint8_t
