Small load cell to interface a microcontroller.

Small load cell to interface a microcontroller for a digital scale.

I need a thin load cell of 5kg capacity to interface with a microcontroller for a digital scale, Is there any small load sensor ? or some other type of weight sensor ? How to get signal to the microcontroller from the load cell? What is the amplification circuit used in between?



Thank you.

Thank you for your reply. Can this give accurate measurements of weight ? I'm sorry I wasn't clear enough. I want to build a digital scale. But not a bulky one.

Load cell will give analog output. For processing the information, you have to connect ADC between load cell and microcontroller.

I need a thin load cell, to measure weight on a surface, sensor height should be about 0.5 cm. Can you suggest me such sensor? Is a strain gauge sensor suitable for this ?

The links you gave me says "Use them to sense if it's being squeezed, but you may not want to use it as a scale." Have you experienced otherwise ? Did you use them to measure weight ?

Thank you. But you are are not getting any value there. I need the sensor to be accurate to 10g or more.

I just bought a load cell in UK with a wireless load indicator and load link. It can capacitate up to 300 tonnes with high accuracy. I think it's more reliable to have this wireless load cell device.
