Can I create a pocket step counter / pedometer just with accelerometer? If yes, can you explain how can I do that?
The device should detect step irrespective of direction of device.

For timed protocol I will turn on and off pinging based on a switch. It won't be on most of the time. But I was thinking about how BLE Beacons work and they continuously ping and battery last from 6 months to 2 years. Can't we do something similar or are they...
I am a product developer but not an electronics engineer. I am doing a cost analysis of a product idea for my company. The product will need something like this...
There will be two small portable devices (A and B) 1 meter apart (not in line of sight since A can be in pocket). Product A will...
I want a device that can either stick on dashboard or like a key fob in driver pocket that will help to detect whether person is in car or not.
Requirements:
- Device must have a detector and siren. When detector detects that person is not in car should buzz siren.
- Can be a device in car or...
Can we use passive infrared proximity sensor ( https://www.adafruit.com/products/466 ) that is used in mobile phones as window sensors? The device (that has sensor) is placed on window glass and when that device detects a window frame it will trigger alarm.
Will it work even if bright sunlight...
Thanks.
Do you know any existing sensors/solution in market using any of the above methods (except switches) for detection? Also, my solution should have a small form factor and it should give accurate results. Will all above suggestions do the same?
What type of engineer(s) I should look for?
Thanks. I guess both these requires to be attached to each window/door. Is there any way we can detect without attaching anything to window/door. Something like motion sensor to figure out window is in motion, measuring pressure of room etc.
How can we detect whether a home window or door is opened or closed using sensors. I know it can be done using proximity sensors and window sensors. I want to know all possible ways/sensors to detect it.
I am no way related to physics so please try to answer considering that :)
Thanks in advance.
