We’ve manufactured 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). In addition, these chips are low-power—very low-power, in fact—making them ideal for battery-powered applications whenever possible. We’re excited 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 10-second interval usually works well). 

Like all SCREEK Wi-Fi sensors, they integrate seamlessly with smart home systems—all it takes is a simple network setup (turn on the sensor, enable the 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 exchange, you don’t have to worry about batteries, and you get benefits like ultra-fast updates—plus, no gateway is required.

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—it’s mini and compact and looks great. We offer two cable options; it’s quite small, which might be pretty fun.

Its overall performance is comparable to the LS2, though it’s slightly more sensitive. To compensate for light attenuation caused by the casing, we’ve optimized the design as much as possible by adding light-gathering holes. Its light sensitivity is excellent, and with extremely low power consumption, 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—our light sensor family now has a compact new member.
