Hello to all,
I am in the process of developing a sensor that will detect the impacts or airborne particulates and am hoping to receive some advice on how feasible this goal actually is. Tentative plans are to use a cylindrically shaped ceramic PE transducer that will output a voltage each time it is impacted. Ideally these impacts will be output in pulse form and these pulses will then be counted and logged, however, as of now I am not able to locate a sensor with the required sensitivity. The other option is to mount a high sensitivity vibration sensor in the collection pan of an instrument we make (BSNE is the name of the device, photos and info @ SoilErosionProducts.com under the “products” tab and also in the attached file) that would possibly detect the small vibrations created by the impact of particles as they enter the inlet and drop out of the air stream into the collection pan of the sampler.
Does anyone have any thoughts on whether or not this is doable and, if so, offer some advice on HW, signal conditioning, instruments amps, op amps, etc. that might be best suited to for the job? Thanks a million in advance for any insight you can offer.
Look forward to hearing any and everything.
Cheers,
