What is the Ohm value of the 30POTDM?

The resistance of the 30POTDM is 500k Ohms. It also has a trim pot to adjust the minimum brightness level.

Some of the key features are:
  • For use with 32/1000 and 32/2400 high power remote dimmers only

Can I stop triggering my SAE_UE_MS_CDBWE sensor when I walk past my room in the hallway?

Yes. the sensor head can be pulled down 30º and rotate in range of 350 º to orient at desired angle for better detection, or avoid from unwanted direction

How does the sensitivity adjustment work on the SAE_UE_MS_CDBWE 360° PIR sensor ?

Sensitivity can be adjust for different requirement by adjust the knob setting or use remote control to set Lux value (10Lux to 1000Lux), time 1 (5sec to 20min), time 2 (10sec to 60min),
the sensor head can be pulled down 30º and rotated in range of 350 º to orient at desired angle for better detection

How to Check Index Fragmentation on Indexes in a Database

SQL Queries taking longer than normal to complete.

When a database is frequently updated via INSERT, UPDATE, or DELETE statements we can expect it to become fragmented over the time.
If database indexes are fragmented, the SQL Server query optimizer may chose a non-optimal execution plan when using an index to resolve a query.
This will affect the overall query performance and you may notice a query behaving slower than normal.

*Warning: Irreparable database damage can occur. This procedure should only be performed by users familiar with SQL Server Management Studio. Databases should be backed up prior to performing this procedure.*

The following is a simple query that will list every index on every table in your database, ordered by percentage of index fragmentation.
SELECT dbschemas.[name] as 'Schema',
dbtables.[name] as 'Table',
dbindexes.[name] as 'Index',
FROM sys.dm_db_index_physical_stats (DB_ID(), NULL, NULL, NULL, NULL) AS indexstats
INNER JOIN sys.tables dbtables on dbtables.[object_id] = indexstats.[object_id]
INNER JOIN sys.schemas dbschemas on dbtables.[schema_id] = dbschemas.[schema_id]
INNER JOIN sys.indexes AS dbindexes ON dbindexes.[object_id] = indexstats.[object_id]
AND indexstats.index_id = dbindexes.index_id
WHERE indexstats.database_id = DB_ID()
ORDER BY indexstats.avg_fragmentation_in_percent desc

This query can be modified to focus on specific tables by append the table name to the 'where' clause:

WHERE indexstats.database_id = DB_ID() AND dbtables.[name] like '%%'

In order to reduce fragmentation we will have to reorganize or rebuild the indexes. Choosing between reorganizing or rebuilding depends on the query results.
For heavily fragmented indexes a rebuild process is needed, otherwise index reorganization should be sufficient.

The following table summarizes when to use each one:
Reference Values (in %) Action  SQL statement
avg_fragmentation_in_percent > 5 AND < 30  Reorganize Index  ALTER INDEX REORGANIZE
avg_fragmentation_in_percent > 30  Rebuild Index  ALTER INDEX REBUILD
