[SOLVED] LTspice 3rd party libraries

[kingkongjong]

Hi

Does any one know if there are any ltspice 3rd party libraries for ultrasonic distance sensor, servo motor, temperature sensor, sound sensor, and light sensors like photodiodes. Basically I am looking for sensor and motor 3rd party libraries.

Thanks

I'm not aware of any 'libraries'.

However LTSpice can import generic spice models provided by manufacturers. So google for spice models of the parts you're interested in.

That said some of the things you mention (servo motor) are somewhat outside the domain of typical spice simulations which focus on circuits and circuit details. You can abstract many things into spice in various ways however you're not likely to find models for such things ready to go.

Tools like PSIM, Plecs and Simulink come to mind as perhaps better tools for simulating system level components.

As asdf44 mentioned, you are essencially looking for devices that are usually in the scope of measurement/monitoring and (loopback) control, which are very often interfaced with microcontrollers; some of these devices are not so simple and their models would be more concerned on the behavioral aspect than on their electric characteristics. Maybe LTspice is not the suited tool for making simulation with those devices, but rather the Proteus or some other of the same strain.
