After we recently sent out a batch of F2(https://docs.screek.io/f2) radars (based on the LD1125F), we have Series 1 (1U, 1M, 1MS, 1W), and Series 2 (2A, https://docs.screek.io/2a) inside the radar. In total, we've made five millimeter wave radars, with a series of radars based on the LD2410, and a series 2 based on the LD2450.
In some ways, we have found that millimeter wave radar is a game changer for body sensors, and the low-cost LD2410 gives us a more reliable option for detecting a person's presence somewhere. The LD2450, on the other hand, can find out where a person is located.
Though there is a not so perfect side to things, they can be affected by ghost, and the fact that sometimes when a person isn't moving around much, they can disappear from the radar's view.
But I don't think we ever want to go back to the days of pure PIR, where we were in a stairwell full of PIR that only lit up when a person walked underneath, and we were standing in the doorway, but the lights went out in the entire hallway!
And now that we see the potential of the F2 for more sensitive static detection (static capability up to 5.5m close), longer distances (extended to 8m relative to the LD2410), and better resolution (roughly capable of 30cm at 8m, compared to the 75cm of the LD2410 at maximum distances), we're eager to see what people think of the F2.
But as a downside aspect, the F2's LD1125F costs close to three times as much as the LD2410, and there's no more bluetooth functionality, or the ability to adjust the sensitivity in segments. That means the ghosting problem is still there and even harder to eliminate. It categorizes detection into close range, intermediate range, long range, and three stages.
Even though millimeter wave radars have some of these issues, we still feel that they conquered our change of detecting the presence of live bodies. And it's really quite interesting to join the world of sensors that make some DIY them!
We've built over 3,000 millimeter wave sensors to share nationally and internationally in the last 12 months.
And for the next generation radar of the LD2450, the LD2461, we've recently heard from the HLK developers that in the second half of February will start investigating the ghosting issue to try to improve it. This is a 5-man dual antenna radar if possible. The static capability of the LD2450 will be enhanced and the number of people increased. But the current firmware is performing poorly.
Thanks to all our reddit friends for their support, and we're looking forward to exploring more sensor types. We recently shared both the external temperature and humidity sensor ths1 (https://docs.screek.io/ths1), the tof range sensor ds1 (https://docs.screek.io/ds1)
Now, we're looking forward to feedback from the first F2 users and hope to see more of how it performs in real-world situations. Is its better static ability great or is it the devil, and does its longer range make any difference? Or is this just another hlk with a digital number meaning.
We'll be taking a week off for Chinese New Year between February 7th and February 13th next week, and until then, we're setting the sensor discount at 10%.
Until February 17th, we can only ship to major European and American countries(Before February 7th), for Africa, Asia (Singapore, India, Malaysia, Japan) and other countries, we will not be able to ship due to the vacation of our partner agents, we are sorry.
