USING THE TEMPERATURE ALARM

There’s a limit to how much distance you can put between your temperature sensor and your Arduino. You could make the lead you attach to the TMP36 as long as 20 feet (7 m), but the sensor will become less and less accurate as the lead gets longer due to electrical noise on the line and the resistance of the wire.

Leave the sensor near the item you want to stay at a certain temperature and watch the LCD. If that wine cellar just won’t stay cool enough, try setting up the sensor in different rooms in your base until you find one with the right climate. If there isn’t a good room for the wine, just put the sensor back on your generator, invite the other survivors in your area over for a drink, and have an antizombie strategy meeting.

Now that you have a bunch of sensors to warn you of dangers in your base, in the next chapter, you’ll combine the Arduino projects with a Raspberry Pi to make a control center.
