I am new at this. I have 3 TMP36 temperature sensors in parallel attached to a 5V regulator and ground. I am passed hooking up the sensor backwards and burning my fingers as most of us learn. But some how after they are hooked up correctly the die and have an output value of 3.8-4.3 volts instead of the .750 @ 25C range. Usually, this happens when trouble shooting, maybe a current spike. Is there a way to protect the temperature sensor without affecting the value out? Diode? The las time this happen they all three were working, plug into analog 0-2 on the Uno. I had a 5VDC on the Vin and switch to 12Vdc since 5 is too low, something happen and they all three died at once.
help in understanding and fixing this from happening again.
