IC LM 35 / TL 431 does not require calibration or adjustment from the outside because of its accuracy until approximately a quarter degree centigrade temperature in the room. Term sensor from - 55 ° C to 150 ° C, IC LM35 / TL 431 is very easy to use, as the work of the indicator display control portion power split. IC LM35/TL431 can absorb a flow of 60 m from supplay so that the heat caused a very low own less
from 0 ° C in room temperature.
