The Sense HAT has a set of environmental sensors for detecting the conditions around it. It can detect:
* Pressure
* Temperature
* Humidity
We can collect these readings using three simple methods:
* {{fname|sense.get_temperature()}} - This will return the temperature in Celsius.
* {{fname|sense.get_pressure()}} - This will return the pressure in millibars.
* {{fname|sense.get_humidity()}} - This will return the humidity as a percentage.
'''1.''' Using these, we could create a simple scrolling text display which could keep people informed about current conditions.
<nowiki>from sense_hat import SenseHat
sense = SenseHat()
while True:
t = sense.get_temperature()
p = sense.get_pressure()
h = sense.get_humidity()
t = round(t, 1)
p = round(p, 1)
h = round(h, 1)
msg = "Temperature = %s, Pressure=%s, Humidity=%s" % (t,p,h)
sense.show_message(msg, scroll_speed=0.05)</nowiki>
