How do I use this phototransistor in a circuit?
Connect the collector to the supply through a load or pull-up resistor and the emitter to ground. The voltage at the collector drops as incident light increases. Confirm the pin order from the datasheet first.
Can I use it for general light sensing, not only smoke detection?
Yes, a phototransistor responds to light in general. Its listing targets smoke detector designs, but it can be used in other light-sensing projects as long as the operating voltage and current stay within its datasheet limits.
