Most of the sensors on the market are for high levels (for warning of
|
|
|
getting a sunburn on normal skin), and so cannot be used.

## Requirements
|
|
|
|
|
|
- Resolution of 0.1 mMED/hr (0.0001 MED/hr)
|
|
|
- (MED/hr is the unit most used by the XP community).
|
|
|
- Display like 199.9 mMED/hr. E.g. a safe indication would be 0.5
|
|
|
mMED/hr.
|
|
|
- Additional symbol (or LED) showing that the level is 0.5 mMED/hr or
|
|
|
lower.
|
|
|
- Allowing an easy indication for small children (smiley, - sign
|
|
|
or other).
|
|
|
- Display on the meter itself (not needing a smartphone for display).
|
|
|
- Allows easy use, less likely that battery is empty (reduces risk
|
|
|
taking).
|
|
|
- No need for continuous measurement or logging.
