Why there is more static electricity or static shock in winters?

Why there is more static electricity and shock in winters?

Before answering the question: why there is more static electricity in winters? we first must understand, why does this happen and why do we get a static shock in the first place?

 

Why do we get static shock?

 

 

Actually, when you move across an insulator, such as a nylon or wood carpet etc., you collect the extra electrons from the surface.

 

Why do we get a static shock?

 

These extra electrons get accumulated on the surface of your body and start building up an electric charge when the amount of electrons accumulated gets considerably high and then you come in contact with a conductor such as a metal doorknob, this charge will jump from your body to the conductor in order to neutralize itself. And in the process, your body will feel a jerk called static shock.

 

Why do we get a static shock?

 

Now back to the main question why is static electricity and static shock worse in winters? 

 

Why there is more static electricity in winters?

The reason is that air is an insulator. It is a collection of gases and is not a good conductor or radiator. Therefore it does not allow electrons to pass through it.

Water molecules present in the air allow the electrons to flow through it.

In warm weather, we don’t suffer many shocks because moisture in the air forms a very thin layer on the surface of objects around us, which conducts the static charge away when we touch anything.

Whereas during winters, humidity is less and thus air is dry. There are very less water molecules and thus electrons do not flow and start building upon your body, which ultimately results into shock.

And here is a fun fact: If you use a heater in winters, the situation may become even worse for you. Why, you ask? Because heaters suck the little amount of moisture present in the air, making the charge build-up process more intense and the chances of getting a shock is increased.

Top IoT Projects for beginners in 2019 using Bolt IoT Device

TOP 3 IOT PROJECTS FOR BEGINNERS USING BOLT

Hey guys in this tutorial we are going to make 3 easy IoT projects for absolute beginners using Bolt IoT device. So if you are looking for a detailed post on top IoT projects for beginners in 2019, then you crashed at the right webpage.

Our first project will be a light monitoring system which can be used for monitoring the amount of light a plant is receiving.

In our second project, we are going to monitor the room temperature using an LM35 temperature sensor with Bolt IoT device and this temperature data will be available to us 24X7.

Finally, in our last project, we will control an output device directly from the internet for example, in this case, the LED strip shown in the above image.

Watch this video to see each of the above projects in action:

 

BUY BOLT FROM AMAZON:

India: https://amzn.to/2TLi2GC

USA: https://amzn.to/2CoAPk0

 

1. LIGHT MONITORING SYSTEM

STEP 1:

For this light monitoring system IoT project for beginners, you need:

1. Bolt IoT Device

2. Breadboard

3. 1OK Resistor

4. LDR or Light Dependent Resistor

Connections for Light monitoring system:

Circuit for Light Monitoring System
Circuit for Light Monitoring System

1. Connect resistor in series with the LDR on breadboard

2. Connect the end of resistor and LDR to 5v and Gnd pin respectively.

3. Remaining terminal goes to the only analog pin available on bolt.

 

STEP 2:

Now go to cloud.boltiot.com in your web browser.

**Next step is setting up the bolt wifi or IoT module, which is very easy to do. It will hardly take more than 5 minutes. Click the link below for instructions.**

Setting up the Bolt wifi Module

After configuring the Bolt IoT device with the cloud for the first time, the homepage will display the device name. It will be online/offline depending on whether the Bolt IoT module is connected to the cloud or not.

Bolt can be powered through a normal 5v mobile charger. Blue light indicates that the device is on whereas Green light indicates that it is now connected to the cloud.

 

STEP 3:

Now its time to create our first project on this Bolt IoT platform. Follow the steps given below for the same:

STEP A: Click on Products– Build new product

STEP B: Give your project a name. Select Input and Gpio option, since we are using an analog pin of Bolt IoT device

STEP C: Click on Configure this product.

Hardware Setup: Select Analog pin A0 from the Bolt pinouts and give this variable a name

Software Setup: Write the code(Javascript) and give it a name. Save and exit.

 

This slideshow requires JavaScript.

 

CODE: 

setChartLibrary(‘google-chart’);
setChartTitle(‘Light Monitoring’);
setChartType(‘lineGraph’);
setAxisName(‘time_stamp’,’ldrip’);
plotChart(‘time_stamp’,’ldrip’);

 

STEP D: Click on “Link device to the product”

 

STEP E: Next step is deploying the configuration from the cloud on to the Bolt Device

 

STEP F: Now click on view this device. A new window will open.

 

STEP 4: Monitor the Data

The graph will look like this. On the y-axis, we have analog values or light intensity falling on LDR with respect to time on X-axis.

Graph between Light intensity on y axis and time on x axis

 

The input data from the LDR to the Bolt device is pushed to the cloud automatically every 5 minutes but you can get the data whenever you want by pressing Push date to the cloud.

The graph shown below shows the analog values received for different light intensity falling on the LDR.

 

This way you can monitor the light 24X7 depending on your purpose.

 

2. Temperature Monitoring System

 

STEP 1:

For this Temperature monitoring system IoT project for beginners, you need:

1. Bolt IoT Device

2. Breadboard

3.  LM35 Temperature Sensor

Connections for Temperature monitoring system:

 

 

1. Connect Vss and GND pin of the LM35 temperature sensor to 5V and GND pin of the BOLT respectively.

2. Connect Vout pin of LM35 to the Analog pin A0 of Bolt

 

STEP 2:

 

Now go to cloud.boltiot.com in your web browser.

For creating this new product we are going to follow the same steps as we did for the light monitoring system.

 

STEP 3:

 

STEP A: Click on Products– Build new product

STEP B: Give your project a name. Select Input and Gpio option, since we are using an analog pin of Bolt IoT device

STEP C: Click on Configure this product.

Hardware Setup: Select Analog pin A0 from the Bolt pinouts and give this variable a name

Software Setup: Write the code(Javascript) and give it a name. Save and exit.

 

CODE:

setChartLibrary(‘google-chart’);
setChartTitle(‘Temperature Measurement’);
setChartType(‘lineGraph’);
mul(0.0977);
setAxisName(‘time_stamp’,’temp’);
plotChart(‘time_stamp’,’temp’);

 

STEP D: Click on “Link device to the product”

STEP E: Next step is deploying the configuration from the cloud on to the Bolt Device

STEP F: Now click on view this device. A new window will open.

 

STEP 4: Monitor the Data

The graph below shows the room temperature with respect to time in degree Celsius for the past two hours.

 

 

Highest temperature was 14.1-degree Celsius and lowest 13.5-degree Celsius.

 

3.  LED Strip Control

 

STEP 1:

For this LED Strip control IoT project for beginners, you need:

Components required for LED Strip Control IoT project
Components required for LED Strip Control IoT project

1. Bolt IoT Device

2. LED Strip

3.  Relay Module

4. Power supply for LED strip

 

Connections for LED strip control:

 

 

Circuit Diagram for LED Strip Control
Circuit Diagram for LED Strip Control

 

1. Connect Relay Module with LED strip

2. Connect the BOLT device with the Relay module

 

 

 

STEP 2:

Now go to cloud.boltiot.com in your web browser.

**For creating this new product we are going to follow the same steps as we did for the light monitoring system except for the first one, here we have to select output instead of input since we need BOLT to give ON/OFF signal to the Relay rather than taking input from a sensor.**

 

STEP 3:

STEP A: Click on Products– Build new product

STEP B: Give your project a name. Select Output and Gpio option.

STEP C: Click on Configure this product.

Hardware Setup: Select digital pin 0 from the Bolt pinouts and give this variable a name.

singleButton({name:”Led On”, action:”digitalWrite”,
pin:”0″, value:”HIGH”})singleButton({name:”Led Off”, action:”digitalWrite”,
pin:”0″, value:”LOW”})

 

STEP D: Click on “Link device to the product”

STEP E: Next step is deploying the configuration from the cloud on to the BOLT Device

STEP F: Now click on view this device. A new window will open.

 

Given below is the required GUI having two control buttons:

LED ON” turns on the strip light

LED OFF” turns off the strip light
