What is my room's temperature ?

One day I was wondering how can I get to know the temperature of my room without going into the room or from anywhere in the world by just saying "What is my room's temperature ? ". Then I came up with an idea that we can achieve this using Bolt IoT.

A temperature monitor which is capable of autonomously recording temperature over a defined period of time. The digital data which is retrieved, viewed and evaluated after it has been recorded. The system is integrated with Google voice assistant and user will receive SMS alerts of his room's temperature.

Lets Build the system:-

Please refer the circuit diagram while connecting wires.

Connecting LM35 to Bolt :-

1. Connect the VCC pin of LM35 to 5V pin of the Bolt.

2. Connect the GND pin of LM35 to GND pin of the Bolt.

3. Connect the analog output pin of LM35 to A0 pin of the Bolt device.

Connecting Bolt to Cloud:-

Please follow the instruction as per the below link to connect the Bolt device to Cloud. Connect Bolt to Cloud..

Plotting Graph on the Bolt Cloud :-

Login into cloud.boltiot.com & you will see the Blot devices is connected to cloud.

click on "+ADD product" tab.

Paste code in Code tab.

Save the project & click on link the product to bolt device.

Graph Output.

Thats it!! Temperature monitoring system has build using BOLT-IOT device.

Lets Integrate Temperature monitoring with google voice assistance. With the help of google voice assistance you can trigger the bolt device and get the temperature value over SMS.
