A quick search in the forum or web didn't get me a satisfactory answer, so I'm asking here again. Also, novice alert!
I purchased a Rev. C sensor for measuring indoor air velocities (,of course). I've connected it to two boards. One is MKR1010 and the other is Wemos D1 mini using an ads1115 analog-to-digital converter. Because Wemos D1 mini has only one Analog pin. I have not yet calibrated it, but it appears to give better results via MKR1010, compared to Wemos D1 mini. May be esp8266 isn't a reliable board for this sensor.
I am planning to use this sensor for thermal comfort studies, where the indoor temperature keeps changing. It fluctuates in the range of 24-30 °C. Basically, the occupants in the space are free to change the indoor temperature, while the air velocity is kept constant. The acceptable indoor temperatures are measured for varying air velocities.
Could you please clarify a couple of things regarding its operation:
- If I calibrate the sensor for a zeroWindAdjustment at a particular room air temperature, does it produce reliable results in indoor conditions when the ambient temperature keeps fluctuating? Or does the sensor work correctly at the ambient temperature it is calibrated?
- Does Rev. P suits the purpose I sated above instead of Rev. C, as it says that it includes hardware compensation for ambient temperatures? Does "hardware compensation for ambient temperatures" mean that it can be used in ambient temperatures other than the ambient temperature it is calibrated for zeroWindAdjustment?
