Hi i want to develop an application to track whether a person is wearing helmet while driving his motorcycle. For this i need a sensor which can be easily installed in existing helmet , Please suggest a sensor which can be used .Purpose of the sensor is just to give a notification / alert to the mobile application when the helmet is put on
Major concerns are
1 . Battery for the sensor should be long lasting
2 Installation of sensor should be hassle free
3. Cost effective

Which mobile application do you plan on using and what distance do you want it to work over?

 

Don't confuse him with all these pesky details, he's gonna be a Millionaire soon.

Both android and IOS application. It should track all the distance covered by wearing a helmet

With that kind of range, be prepared to pay a subscription for a satellite link! We are not a free engineering design team. That is your responsibility. We will try to help when you run into a problem. Your next step is to write a detailed requirements specification. Then you can decide which hardware will be required.

 

What is the usage scenario? I know whether I am wearing my helmet or not. Why do I need a sensor to tell me that?

 

just recommend him a sensor if you know one....... even a freakin' microswitch....

I think you misunderstood my requirement, I just need the sensor to give a signal to the mobile application all the tracking will be done in the mobile application

So what is the mobile application?

 

What do you care? Seriously? Sometimes there are endless questions on a thread completely straying away from the main topic.
At least ask something reliable as:

To what extent do you plan to modify the helmet in order to mount the sensor?
Would you glue it? Would you drill the helmet to mechanically fix the sensor?

A few microswitches on carefully chosen spots could do the trick but the mounting would be a real problem.
Also there are some flat capacitive sensors that you could use... but again... how you gonna mount them?
Also you would need a battery and some kind of wireless transmitter, where are you going to place those?

 

I want to develop an application which will track whether a person is wearing a helmet while driving or not .

Let me rephrase: Why do you think anyone would want such an app?

Here is an example: A parent might use it to make sure their teenage son was wearing his helmet all the time. But, in all likelihood it would be easily circumvented.

So who and see as a customer?

 

I thought this was electronics forum, not entrepreneur consulting website.

I understand that some people are not clear what they want and usually whoever wants to help them has to ask 10 more questions, but the guy wants a sensor that could be mountable (and removable???) on a helmet.

Hi thanks for the reply , My purpose is to install an IR( Infra red) type of sensor which can be easily installed inside the existing helmet . So please suggest me how can i manage the battery of the sensor

I do understand that this is a electronic forum , I want some information regarding an electronic item so i have posted my query in this forum . And yes regarding my requirement i have made my self very clear in the starting saying that i just need a sensor which can be easily installed in helmet and purpose that sensor is to just send signal to the mobile application that the helmet is put on by the concerned person

I have some plans regarding the development of the application, If possible please suggest a sensor which can serve my purpose

 

Dude, I am defending you if you did not notice

The problem is not WHICH sensor you gonna choose, I would say it is HOW do you plan to install it?
Lets say you get a pair of IR diode and photodiode (this was one of my first thoughts).
Theoretically, it will work great. The problem is, how is this doable to be additionally bought and installed on existing helmet, and if needed, to be removed without any trace?
What I thought would be a cool solution, is a hidden layer inside the helmet with 5 microswitches in a cross-allignment, so when you put your helmet on your head they all click. That is even harder to pull out on existing helmet.

The problem you have is not exactly electrical, it is generally a concept (design) issue.

I can think of at least 3 types of solutions (microswitches, IR pair, capacitive sensor) but for each of them it is the same obstacle: how you gonna mount any of them?

Thanks for writing back again . Mounting and all i think it can be possible by installing the sensor using a glue type material into the helmet . Can you just explain me how a micro switch will transmit the data to a mobile application saying that helmet is put on by the person

 

Without knowing the purpose the product, it is only guesswork to make any suggestion, since I don’t know what is important.

But here goes:

Put an RFID reader in the helmet and embed an RFlD chip in the rider’s skull. Make sure to use rolling codes, so that the RFID cannot be duplicated on a melon. This will offer at least some immunity to attempts to defeat it. But it will still be vulnerable to the user digging the chip out of his scalp and installing it in a melon.

Yes, this is a silly answer. But you have given me no reason to think your question is not silly.
