Description
Arduino Weather Station v1.0 (BMP280)
First version of a very simple weather station made with an Arduino UNO, a BMP280 sensor and a LCD.
I'm already working on the v2.0 (which will be wireless), so keep up with me to stay updated! ;)
Code
Arduino Code
C/C++
BMP280 bmp; //Initialize your sensor LiquidCrystal lcd(12, 11, 5, 4, 3, 2); /*Initialize your LCD, make sure you wired it correctly */ double T = 0; //Starting temperature value double P = 0; //Starting pressure value char measure = 0; void collectData() { measure = bmp.startMeasurment(); if(measure != 0) { delay(measure); measure = bmp.getTemperatureAndPressure(T, P); if(measure != 0) { P = P + 17; // '+17' is a correction for the sensor error T = T - 0.8; // like said above lcd.clear(); lcd.print("T: "); lcd.print(T); lcd.print(" C"); lcd.setCursor(0, 1); lcd.print("P: "); lcd.print(P); lcd.print(" hPa"); } else lcd.print("Error."); } else lcd.print("Error."); } void setup() { lcd.begin(16, 2); pinMode(contrast, OUTPUT); pinMode(brightness, OUTPUT); analogWrite(contrast, 100); // '100' and '255' are the contrast and brightness analogWrite(brightness, 255); // values I suggest, but you can change them as if(!bmp.begin()) { // you prefer delay(1000); lcd.print("Init. failed."); lcd.setCursor(0, 1); delay(1000); lcd.print("Check wiring."); while(1); } else lcd.print("Init. OK."); bmp.setOversampling(4); delay(2000); collectData(); } void loop() { collectData(); delay(2000); }
