I have been searching for a sensor that trigger a response with an air pulse. I have BMP180 and BMP280 sensor that I am currently working with, but the BMP280 refresh rate is too low for my application at 1Hz( As far as I can tell it wont refresh fast enough and that is what I am reading through my searches). Although the BMP180 does seem to work in my test conditions I am worried if dirty air may hinder it's reading in the long run, additionally I need two sensors working simultaneously and the BMP180 library has a fixed address for I2C(I attempted to make a modified version for a different address with no success, but I believe that is my lack of knowledge). Ultimately I am not interested in measuring pressure itself, but a pulse of air pressure. The program is currently written to detect a sudden increase in pressure to trigger, but that is only because I am using pressure sensors for the reading. Please advise, I would be grateful.
- Has to respond to air pulse.
- Faster than 50ms refresh(20Hz), but ideally lower than 15ms.
- Low power(Will be on batteries).
- Need 2 separate readings.
