For those who are often confused by series 1 disturbances, the whole parameter adjustment may just seem confusing. Our general recommendation for this is to use the HLKRadarTool APP to dynamically see what is happening. However this chart is also difficult to be confusing at first.
Here we will try to do some explanation:
- In the chart triggers will be categorized as static and dynamic, which represent active and slightly moving targets respectively. The difference between these is that we like to think of large movements as triggering dynamics, whereas when you are barely moving, this will be considered static (e.g. sitting, when there is only a slight body undulation such as breathing).
- The numbers 1 to 8 below each energy represent gates, and each gate represents a pitch; they could easily be misinterpreted as historical times, but they are not.
- The red line represents the set parameters, this is what you can adjust, each gate corresponds to a Sensitivity, by adjusting a threshold high or low you decide what is a valid trigger.
- The blue line represents the current detected energy value, when the energy value is higher than the red value of the corresponding gate, you get a trigger.
- Note that the gate behind the trigger often triggers as well, it's like a signal reflection, because it has to go through you to detect the place behind it.
- If you want to understand what wrongly triggers your radar, stop, take a deep breath, let it open the app when it is wrongly triggered, and watch carefully for a while on the front page those waveforms rise and fall, and you'll understand that something is in front of the radar causing the radar to see it as a valid feedback signal. If this interference is not very strong, like a small fan, which has an energy of 30, 40, then a proper jump in the Sensitivity of the corresponding gate will allow it to consistently produce a signal without interference. Of course, this will sacrifice a little bit of responsiveness to tiny human movements, but it's useful for avoiding interference.
- This is probably the most confusing in the parameter settings! You need a conversion interval, which is indicated in the figure below where each red sensitivity corresponds to the one set in the settings.
- There is a parameter that determines how long each gate represents, there are 0.75m and 0.2m and they affect the maximum distance of the radar, which is usually 0.75m (this means the 8th gate, which equals 0.75m x 8 = 6m)
- If you don't want a certain distance measured, set the sensitivity of this gate to 100 and it will never trigger. Note that this includes static and dynamic, you can set them both to 100 then both will turn off.
- For example if you only need detections in a distance of 3m, then any gates after 3m can be set to 100 and they will never trigger!
- Conversely, if you only need the ones beyond 3m, you can set all the ones before 3m to 100.
