# :sweat_drops: Computerteknologi HF1 - Klimaanlæg
Mark Pedersen & Mads Finseth 18-06-2020
Redigeret til Github af Mads 26-07-2020
## Projektbeskrivelse:
Vi har lavet et klimaanlæg, hvor en blæser sætter i gang hvis temperaturen er over 28C.
Vores projekt består af følgende komponenter:
- GrovePi
- Raspberry Pi Model B Rev 1.2
- Strømforsyning (PSU)
- 12V kabinet-blæser
- GrovePi Relay
- GrovePi DHT11
- GrovePi LED
- GrovePi Display.
1 stk. blæser forbundet til en strømforsyning.
En temperaturføler som aktiverer vores relæ, når temperaturen overstiger 28 C grader.
En LED vil begynde at lyse når blæseren starter. Når temperaturen er under den værdi vi har sat, slukker både blæseren og LED igen.
LED Display som viser temperaturen.

## Vores kode:
```python
# Imports the libraries that we use
import time
from grovepi import *
from grove_rgb_lcd import *
# Sets the port for Grove-Relay @ D4
relay = 4
# Sets the port for Grove-Temp @ D7
sensor = 7
# Sets the port for Grove-LED @ D3
led = 3
# Sets components to Output
pinMode(relay,"OUTPUT")
pinMode(led,"OUTPUT")
# DHT sensor input
blue = 0
# Creates a loop, where we test for the temperature and turns on the fan and LED if the temperature gets above 28C.
while True:
try:
[temp,humidity] = dht(sensor,blue)
if math.isnan(temp) == False:
print(temp)
setRGB ( 210,55,30 ) # Sets the display colour
if float(temp) > 28.0: # Sets the target temperature
digitalWrite(relay,1) # When the temperature is above 28C turn on the Relay (fan)
digitalWrite(led,1) # When the temperature is above 28C turn on the LED
setText ("Temperaturen er " + str (temp)) # Writes to the Display
time.sleep(5) # Sets a timer for 5 seconds
else:
digitalWrite(relay,0) # When the temperature is below 28C turn off the Relay (fan)
digitalWrite(led,0) # When the temperature is below 28C turn off the LED
setText ("Temperaturen er " + str (temp)) # Writes to the Display
time.sleep(5) # Sets a timer for 5 seconds
except KeyboardInterrupt:
digitalWrite(relay,0) # Turn LED and Relay off before stopping
digitalWrite(led,0) # Turn LED and Relay off before stopping
break
except IOError:
print ("Error")
