ST-309 is a smart home control system that can help users manage the various smart devices in their homes, and control the on/off, brightness, temperature, etc. of devices through the mobile App
The document describes the Koden ST-309 as a double-type high-sensitivity silicon phototransistor molded with visible light-cutting resin. It is noted for its compact size, making it optimal for use in optical mice and encoders.
Key features include a side-viewing plastic package and built-in 2-channel phototransistors. The datasheet provides maximum ratings such as a collector-emitter voltage of 4V and operating temperatures from -25°C to +85°C, along with electro-optical characteristics like peak wavelength at 800nm. This manual is written in Japanese.
