Open a browser and visit your Raspberry Pi Vivarium Controller "manual Controls" page and test your fans
NOTE: Buttons will show what will happen when clicked, not the current state of the device.


STEP 3

Set the Fan's humidity threshold
sudo nano /var/www/html/fanh1.php
Edit the threshold of your desired value
Repeast for fan #2
sudo nano /var/www/html/fanh2.php



STEP 4

Create a cron job to regulate humidity
* /5 * * * * php /var/www/html/fanh1.php
* /5 * * * * php /var/www/html/fanh2.php



FINISHED

The Raspberry Pi Vivarium Controller will check the humidity readings every 5 minutes and authomatically turn on the fans if the humidity is above your threshold
Your may use the same method to control other vivarium components such as heaters, misting and lighting.
