I'm new to electronics and I'm trying to design some circuits and blocks on my own.
I'm making a block to measure temperature in a range between 2ºC and 50ºC, by using the sensor LM35. I have set the circuit (which is pretty basic) in a Protoboard and it works. However, I'm wondering if there is any way to maximize the resolution (currently, I obtain a resolution of 0.1mV). I am using a ISO TECH IDM 203 multimeter (which is 3 3/4 digits).
I thought that this could be done with an amplifier. But my knowledge of amplifiers is not very good.
Is this feasible? And any idea on how to start to do it (or what OpAmp block should I use)?
