WebJun 29, 2024 · It can be used with single power supplies, or with plus and minus supplies. As it draws only 60 µA from its supply, it has very low self-heating, less than 0.1˚C in still air. The LM35 is rated to operate over a −55˚ to +150˚C temperature range, while the LM35C is rated for a −40˚ to +110˚C range (−10˚ with improved accuracy). WebMay 6, 2024 · You also don't appear to actually be changing the LED: You've initialized led=P1^0, so led is ending up set to whatever P1^0 (I'm guessing that's the port register on the 8051's?) is at startup, and then you assign other values to it. But nowhere do you write the new value of led to P1, so you're not changing the pin anywhere after setup().
