The sensors are for weather sensing, temp: 0-50C, baro: standard barometric pressures, humidity: ~0-100%RH. The sensors will be mounted in a very small package installed in a race vehicle. While a vibration intense environment, it's never operated in wet or freezing weather, and there is no need for anything more than minor water/weather proofing.
More info: the receiving device is a logger, it captures data at up to 1000/second, clearly many times faster than any sensor. I can sense as often as needed. While I'd like to maximize resolution (e.g. spread the results over the 0-5v as much as possible), I don't care about error rates, noise, etc. I will filter and calibrate all that in the resultant software. I just want the raw data from the sensors.
Is that enough info?
