One of the most exciting features of IoT is that it allows us to control devices remotely.

Imagine:

• You are outside your home and forgot to turn OFF the fan. With IoT, you can switch it OFF using your mobile phone.

• A doctor can monitor a patient’s heart rate and suggest medicine even when the patient is at home.

• Farmers can water crops while sitting in their village office.

Remote control through IoT is possible because devices are connected to the internet. When you press a button on a mobile app or dashboard, the signal travels across the internet to your device (like fan/LED), and the device responds instantly.

This is how smart homes, remote healthcare, and industries are becoming more efficient.
