Open box vs Closed Box Temperature Noise of AD590 circuit and sensors |
|
|
- I removed the temperature sensing circuit from the insulated box and opened the smaller metal box it was in. This left the circuit open to the air for the whole duration of the measurement.
- The original data was taken from 8 am to 1 pm, while the open box data was taken from 3 pm to 8 pm. There was most likely more activity in the room for the open measurement.
- The closed data is less noisy before about 0.2 Hz, but the open data actually becomes one order of magnitude less noisy by 7 Hz.
