#Project Objectives
#Read temperature and humidity values from the DHT22 sensor
#Display the sensor readings in the console
#
#Hardware connections used:
#DHT22 Vcc Pin to 3.3V
#1k ohm pull-up resistor
#DHT22 GND Pin to GND

#modules
from machine import Pin
from time import sleep
from dht import DHT22

#creating a DHT object
dht=DHT22(Pin(14))
led=Pin(0, Pin.OUT)

#continuously get the sensor data
while True:
    #getting sensor readings
    dht.measure()
    temp = dht.temperature()
    hum = dht.humidity()

    #display the values of T and H to the console
    print(f"Temperature: {temp} C  Humidity: {hum}%")

    #read the values from sensor every 2 secs
    sleep(2)

    if temp>25:
        led.on()
    else:
            led.off()
