Intro

Thank you for supporting our DIY project Human Sensor 2A and we look forward to exploring its possibilities with you! We want to provide as sturdy a hardware as possible, giving us the freedom to brush the firmware to offer more possibilities.

Note Site~

Since there is so much information on the 2A in real time and there is test firmware, we will be doing a real time sync update on the Notion site with all the relevant knowledge for the time being.
Hopefully this will help people explore it better.

Note

After that, we will slowly update the information document here.

For the time being, this is the communication and support channel we offer, go to Contact.

Intro~

It uses the hlk-ld2450 sensor and has some very interesting features: tracking the position of the human body and tracking the position of three people at the same time.

In case you're confused about our models, this is what 2A looks like.
It is a middle square box.

Identify your sensor model, 2a is a square box.

Beta Firmware~

Please go to the Note Site and we will synchronize the updates there.

https://docs.screek.io/2a/beta

To be done~

As we're scrambling to build and test more 2A sensors, we'll be updating this place soon to add firmware updates, connectivity guides, some future additions of usage scenarios, and more.

Since the 2a and 1u use the same esphome system, the connection guide for the 1u is also when the 2a.

Note

👻We'll be back soon to complete the documentation here!
