= General information =
{{:NIS Overview}}

= Mechanics =
* Dimensions 60 x 95 x 85mm (109mm including fixing brackets)
* 96mm spacing between brackets
* IP 65
* Solid ABS & PC material

= Luminosity sensor properties =

* low power
* high sensitivity
* Optional RGB spectral response
* reject IR in light sources
* rejects 50Hz and 60Hz flicker caused by artificial light sources

= Wiring =

There is nothing to be wired, because the sensor is integrated. It is mounted on the surface of the housing cover.

== Uplink data Frame format ==

The uplink payload contains multiple fields: <mask>: bit field on 1 byte indicating the presence of other fields. Bit 7 is always to 1 because the mask is never extended on next byte.

Some examples (in hexadecimal):

“820119”: the frame indicates

== Downlink Frame format ==

The sensor configuration contains the following fields:

<up_frame_mask>: the mask identifying the different fields present in uplink frames (possible values are described in “Uplink data Frame format” section)

The downlink frame has the following format:

<cmd>: 1 byte containing WRITE_CFG_CMD=0x02

== Power consumption ==

Power consumption calculator based on the number of measurements and transmissions.
