TV Sensor

Purpose:

I have built this project to keep a check on children how much time they spend on TV when parents are not at home.

Working:

The Bolt Wifi IoT device regularly senses the light intensity of the television and as soon as the light sensor input value goes above Z-score upper limit, it sends a message to the user stating TV has been turned on. Now, after some time the z-score changes dynamically on the basis of continuous input of light sensor and sends a message to the user when the TV is turned off when the input value falls below the z-score lower limit.

Technical Requirements:

1. DigitalOcean account: To work with Python-based code execution.

2. Twilio SMS service account: To send SMS to the user on the basis of conditions satisfied by python code.

3. BOLT wifi module with light intensity sensor and 10k ohm resistor: The hardware configuration is below.

4. A television.

Output:

On execution of my python code, the outputs recorded were somewhat like the ones displayed below :

Since all my number is on DND, SMS was not delivered but we can check the report on Twilio dashboard :
