What would be the equivalent load of a Temperature sensor? or how can I measure it?

Can I assume an equivalente 1k Ohm load for a WSN?

I need this value to design a rectifier. I'm confused, hope you can help me.
 

Hi,

A temperature sensor can be:
* digital
* thermocouple
* ptc
* ntc
* semiconductor...

Maybe you first should specify what to use..then read it's datasheet.

I'm using an LM61. It's an analog sensor. But none datasheet specifies the equivalent resistive load of the component.
I dont think I can measure that with simply a multimeter, did I?
 

Hi,

I don't know what datasheet you used.
I opened the first datasheet that google showed. It is the TI datasheet.
On page 4, chapter "6.5 Electrical characteristics", parameter "output impedance".

This specifies the signal source.....but what load you connect depends on you.
There is no need for a dedicated load resistor (as you can see in the application circuits)...usually it should be high impedance to reduce errors.

Thank you, my bad.
