We have diy a variety of light sensors—the wired LS1 and LS2—and now we’re adding a new member to the family: the LS3004. It uses TI’s OPT3004 light sensor chip, which offers excellent resistance to IR interference (ensuring it detects only visible light). Additionally, these chips are low-power—with extremely low power consumption—making them ideal for battery-powered applications whenever possible.
We’re thrilled to embark on this new adventure with the LS3004, housed in an even more compact enclosure. As before, it features flexible update settings (you can choose between faster or slower updates; the default of once every 10 seconds usually works well).
Like all SCREEK Wi-Fi sensors, they integrate seamlessly with Home Automation (HA)—simply pair them (turn on the sensor, create a hotspot, connect to the hotspot, and select your Wi-Fi network) . We haven’t enabled BLE pairing because BLE is constantly broadcasting, and it seems to generate more unnecessary signals. All in all, it’s the kind of sensor you can easily integrate into Home Assistant in under a minute. The wiring might be a bit of a hassle, but in return, you get the benefits of not having to worry about batteries, ultra-fast updates, and no need for any gateway. The open-source ESPHome system is also reassuring—it protects your privacy and runs reliably on your local network.
We hope you all have fun with it.
We’re excited to DIY a light sensor based on a TI solution. Its mini, compact design looks great, and we offer two cable options. It’s quite small, which might be pretty interesting. Its overall performance is comparable to the LS2, though it’s slightly more sensitive. To minimize light attenuation caused by the casing, we’ve optimized the design as much as possible by adding a light-gathering aperture. Its light detection performance looks excellent, and its power consumption is very low—it’s a truly remarkable low-power light sensor. We believe there will be many more exciting applications for it in the future. In short, this marks a new beginning, and our light sensor family now has a compact new member.
We’re offering a 10% discount to the first batch of brave adventurers. Welcome to our new adventure :)
