We are pleased to introduce our second product, which is an environmental light sensor, it contains a light sensor (BH1750), the core processor is ESP32-C3. it is all integrated together, so it looks like a beautiful DIY electronic hardware, the shell has been carefully designed, it becomes a whole, without the use of screws It is the best part of it.
I think this is one of the biggest concerns, how they look like as shown in Home Assistant, here's how it looks on the interface, it has all this information, integrated together, and we can't find anything more rare. Because it is WIFI-powered, it can be very capricious to give feedback in very real time, without worrying about the battery products that do not update for a long time because of voltage and power consumption problems, and only have updates when changes happen.
As a price, you need to find a suitable installation location and method for the USB cable. Fortunately, we are using the current very popular TYPE-C interface and it is easy to find a cable that fits it.
This is the inside of it, you can see the three modules combined together, we didn't make a separate PCB, but we bought dozens of modules and chips and combined them with each other to find inspiration, we found this beautiful combination, after a long time of testing, it was considered stable, we liked the combination and we designed the shell for it. Then it became a gadget for ESPHome combination.
this bottom structure, it's really delicate, CSZ's clever design makes the module and structure lie nicely inside, it's kind of amazing inside and makes the whole PCB completely different.
