A Temp. Monitor for boats to measure outside- and inside temp and humidity
Required hardware: Arduino mini (a ATMega 168 is sufficient) , LCD Display 4 x 20 with I2C-adapter FC113, DHT22 Sensor, DS1820B, 12 to 5V DC-DC adapter, LDR
The address of the DS1820B has to be identified and inserted into the code prior programming. The display can be dimmed in darkness. The threshold of the dimming can be adapted by changing the value "if(analogRead(3)>= 200) //threshold" The min brightness is defined by the value " analogWrite(LCDPin, 10); // dimmed brightness"
