Value returned will be pressure in units of Pa.HC-05 Bluetooth Modules are the go-to Bluetooth modules for any Arduino project! It’s easy to hook up and code in the Arduino IDE.
b5 is also required so bmp085GetTemperature(.) must be called first. Static void print_float(float val, float invalid, int len, int prec)įor (int i=7 i= 1000 ? 4 : vi >= 100 ? 3 : vi >= 10 ? 2 : 1 Serial.print("\n") // delay before next reading: add a small delay between pin readings. do this but haven't tested the importance Add a small delay between pin readings.

b5 is calculated in bmp085GetTemperature(.), this variable is also used in bmp085GetPressure(.) #define BMP085_ADDRESS 0x77 // I2C address of BMP085Ĭonst unsigned char OSS = 2 // Oversampling Setting It requires the use of SoftwareSerial, and assumes that you have aĤ800-baud serial GPS device hooked up on pins 3(rx) and 4(tx).
* This sample code demonstrates the normal use of a TinyGPS object. I wanted to off-load the sensor readings to an SD card as needed, but before I can even code the SD functions, the mere inclusion of the SD.h library renders my code useless. I'm having some very weird issues using the following hardware elements:
