Don’t Let Your Roommate Take your Snacks!

Temperature monitor and alert system making use of IoT, which alerts us if there is any problem.

1. IN INDUSTRIES

This project is about temperature monitoring, which is used in the medicine manufacturing. During the manufacture of medicines, the constant temperature should be maintained. If the temperature crosses the limit, then all the manufactured medicines must be discarded. To avoid this huge loss, this temperature monitoring system can be used. This system sends an email whenever the temperature crosses the threshold and whenever the temperature changes suddenly.

2. HOME SECURITY

This is about home security. The system is connected to the door handle, so that we get the mail whenever someone touches the handle. The time limit can be set in the program, so whenever there is no one in the home or at night we get the mail as soon the person tries to enter the home.

3. POLLUTION CONTROL

Using this system, pollution can be controlled. We can set the count in the program, which counts the number of times the fridge is opened and sends the mail. This makes sure that the usage of fridge is reduced! Which shows major impact on depletion of ozone. As we use refrigerator less, amount of CFCs is released is less. This reduces the ozone layer depletion and hence our earth is protected.

I have used BOLT Wi-Fi module to do this project.

Final output of the project is shown in this video.

Step 1:

Login to cloud.boltiot.com and note the ID of your Bolt Wi-Fi Module.

Plug in the bolt module, link the device to the bolt cloud.

Circuit connection is done as shown in the picture.

Go to the product and change the configuration of the product.

Complete the hardware and code part as shown in the screenshots.

Go to devices and view the actions.

Now the Bolt part is completed.

Step 2:

Get API key and bolt device number.

Step 3:

Login to mailgun.

In the site app.mailgun.com

Go to domain information and note down all the values.

Step 4:

Create a python file to store all APIs, keys and secret tokens of Bolt and mail and name it as email_conf.py

Keeping bolt module in refrigerator for 2 hours we get the minimum and maximum temperature, using which we can get to know if the temperature is below or above the threshold by an email sent to us. Download the data from the Bolt 'view this device'. Analyse it and use the value in the program.

Using Ubuntu write the python code as shown in the screenshots.

The output will be similar to this.

We have used z-score analysis for detecting an anomaly which sends an email of sudden change in temperature.

This is the email sent to your mail informing about the anomaly.

Similarly home security program is also written with different temperature. Using Bolt collect the room temperature and note down the maximum and minimum room temperature. Give the limits of human body temperature, so that when someone touches the handle an email will be sent.

This the mail sent to us, when the human body touches the door handle.
