Hi
I am rather new to 1 Wire - but pretty impressed so far with the easy of getting things working. Has anyone out there set up a Vibration Sensor for 1-Wire? I am thinking along the lines of finding a sensor that produces 4-20mA and using a DS2450 to convert to 1 Wire. Has anyone got other ideas?

Hi
Thanks for all your suggestions. Yes will use the DS2438. I am looking at some accelerometers that give out 4-20mA. Seem to be very expensive. Will continue looking for a cheaper sensor.

Sorry, I had to jump in.
Accelerometers are not good at measuring vibration. Accelerations are measured instantaneously and are designed to operate above the noise floor of the sensor. The accelerometers have filters to remove the noise to give less erratic readings. The filters are a best guess by the designer of the maximum meaningful rate of acceleration change (jerk) vs the amount of noise to allow through. Most tend to lean toward heavily smoothed readings. Vibration sets the noise floor of acceleration in rough terms. You need something that internally integrates the various frequencies of noise into RMS and peak vibrational energy measurements. Depending on what you want, it is often better to measure the vibration in multiple frequency bands. My guess the specific reading regimens are driven by the military and space applications areas, they are the most demanding/knowledgeable about the area. Things shake quite a bit on rockets and ships, and the equipment needs to be able to survive that. I have never needed to deal with this, but can get more information from a friend if others want it. At higher frequencies, it becomes audio noise and then it's a whole different set of techniques and constraints (microphones, SPL meters.) jerry On 01/11/2012 02:14 AM, Mick Sulley wrote:

Hi
Thanks for your comments - I am finding out that Vibration sensing is pretty specialised - seem to be mainly designed for rotating machines and various vehicle applications where the sensor produces an RMS output over time.
