Atmospheric-Pressure-Sensor

Datalogger using Arduino Pro Mini,BMP085 sensor, DS3231 RTC to display timestamp,pressure,altitude,temperature on a 20x4 LCD display and log CSV data to serial port. Hardware schematic available on

Uses Taskscheduler to poll data from the sensor (https://github.com/arkhipenko/TaskScheduler)
Taskscheduler is very useful and easy to use, see this skeleton code:

#include <TaskScheduler.h>
//Taskscheduler callback methods prototypes
void t1Callback();
void t2Callback();
//Tasks
Task t1(1000, TASK_FOREVER, &t1Callback);   //run t1Callback at 1 sec interval forever.
Task t2(3000, 10, &t2Callback);             //run t2Callback at 3 sec interval 10 times.
Scheduler runner;

void t1Callback() {
	//code here executes at 1 sec interval.
}

void t2Callback() {
	//code here executes at 3 sec interval 10 times.
}

void setup() {
	runner.init();
	t1.enable();
	t2.enable();
}

void loop () {
	runner.execute();
}
