Static, active 
threshold 

 

 

Active threshold 

The active threshold can be changed by the gateway issuing a command; 
Active activity threshold range is 0x0003-0x00FF (default is 0x0003); 
The scale factor of the threshold is 62.5 mg, and g is the gravitational acceleration at standard 
atmospheric pressure. 

 

Static threshold 

The Inactive static threshold can be changed by the gateway issuing command; 
Inactive static threshold range is 0x0002-0xFF (default is 0x0002) 
The scale factor of the threshold is 62.5 mg, and g is the gravitational acceleration at standard 
atmospheric pressure. 

 

Example

 

if you need to set the active threshold to 10m/s

²

, you need to set the value to 10/9.8/0.0625=16.32. 

The last value obtained is an integer and is configured as 16.

 

 

 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Example of threshold configuration: 

 

Assuming that the active threshold is set to 10m/s2, the value to be set is 10/9.8/0.0625=16.32. The last value obtained is an integer and is configured as 16. 

Assuming that the active threshold is set to 8m/s2, the value to be set is 8/9.8/0.0625=13.06, and the last value obtained is an integer and is configured as 13. 

 

Configure device parameters ActiveThreshold=16, InActiveThreshold=13
