| Assembled 2N3906-transitor based temperature sensor |

I'm wondering if anyone is aware of ready-made (assembled, ready for mounting) 2N3906-transitor based temperature sensor, i.e. that is not intended for PCB temperature measurement, but as standalone sensor that can be mounted somewhere inside enclosure. I'd like to use it with I2C fan controller. Ideally, it has to be similar to this one but with transistor instead of NTC. Thanks in advance. |

Whats wrong with using LM335? Its used for batteries and power supplies. |

Nothing is wrong with LM335, but I need external sensor that is going to be connected to I2C fan controller that is expecting 2N3906 "diode" temperature sensor. I'd like to skip soldering of mentioned part to the wires and connector but looking if such assembled solution exists. |

Confused... it's three pins soldered in a diode configuration (IE two wires). I don't see any value in complicating that. It's intended to be "easy". Just make a quick PCB with a 2pin connector and the 3pin transistor and wire it. Done. What am I missing? |
