I like the fact that you present not only how things work but how they are used. My only question is how did you come up with 990 and 490 ? At 19mv/G and a range of +/- 50G the voltage to the ADC would be 1.5v to 3.5v so the counts would be 307 to 716 if a 5v reference is used out of the ADC.
The accelerometer has a programmable gain output buffer stage where you can add resistance values to get a sensitivity output range from 40 to 200 mv/G. I added gain to this stage to make the circuit sensitive to impacts from a screwdriver handle. I can't remember how much gain I used but the values used in my code reflect the added gain.
hey man thanks for the videos these are a good insight for someone new to this technology if I want to measure up the impact of a device to the ground, should I use a force sensor or an accelerometer
@@0033mer thanks for replying. I was thinking the accelerometer also measures the force while the device is in motion (falling) while the resistor only detects and measures the impact with the ground which is what I needed
Hello I was wondering in your opinion or anyone who knows electronics opinion and help. What would be the best sensor to use if I wanted something to flash an LED or turn on an LED after you hit a target with a ball basically you throw a ball hits a Target and a strobe light comes on or a light LED light comes on
im new to doing stuff like this, but I want to make something that would turn a light on when it detects any amount of deceleration and stay on until its stopped or starts accelerating. is this how i would have to do it or is it a different way
An accelerometer can detect acceleration/deceleration and output "g" force values which can be used to trigger an indicator. Check out the ADXL345 accelerometer.
Analog Devices has discontinued making the ADXL50. A similar accelerometer you could use is the MM7361 by Freescale which is a 3 axis accelerometer. Check out this video: ruclips.net/video/Qcq5LdVYc5c/видео.html
Very cool stuff. We've come a long way.
thanks a lot for this i am working on making a impact detection device and your video really helped
Bro where did u get that sensor pls respond, I need an urgent help,pls respond , I'm from India
HRP Productions hey I got it from robu.in and they ship from Pune via FedEx support for the product is really good. I am using MPU6050.
@@eyeversion will it detect impact as shown in this video like he s tapping in different axes and it gives an output
@@eyeversion bro pls respond
@@hrpproductions53 it will for sure. Learn concept from this video and you can get few sketches from Google to play with.
Very helpful...these Sensors are awesome!!

Very educational, thanks. Which Forth you are using? Is it a cross- compiler ?
I am using Flashforth which runs on the microcontroller for program execution and development..

@@0033mer I have a arduino and accelerometer already, but it's the coding and wiring to the vehicle that I'm unsure about
Hello, Do you want to share your code for this sensor?
Code starts at 2:45. It is written in Forth. I do not use the Arduino IDE.
Where can you get this Accelerometer?
Analog Devices has discontinued making the ADXL50.
A similar accelerometer you could use is the MM7361 by Freescale which is a 3 axis accelerometer.
