I'm a beginner when it comes to electronic circuits and came across this schematic diagram for a class exercise. It's my first time coming across this certain component (encircled). It does say it's an LM35 temperature sensor, but the LM35 only has 3 pins, while this one apparently has 5. Any idea what it is?
If it'll help, here are some details about the exercise:
- Title of exercise is Temperature Modeling
- Materials/Components to be used include: a 12v brake lamp with socket, lm35 temp sensor, lf353 op-amp, mc4741 op-amp, tip35c transistor, and some resistors and bourns trimmer
- The objective is to record the output voltage per time interval
