Hi there, I need an advice to read the value from a TMP36 temperature sensor.
I connected:
PIN1 to VCC (5V from Arduino UNO board, tried also with 3.3V)
PIN2 to A0 (analog input)
PIN3 to GND (GND of arduino UNO board)
No resistors or capacitors are connected to this section of the circuit.
Then I uploaded a simple sketch to read the value.
The read values (from serial monitor) are right, but the TMP36 gets very hot, so the values keep raising.
At about 100°C I unplagged the power in order to save the component.
Ok Mike, I've tried adding the capacitor (today I have only a 0,47uF), but nothing changed.
Power supply is the 3.3V supply from arduino board (tried reducing input voltage).
I also tried unplugging the analog output pin of the sensor (just to be sure that the problem is on power supply side..)
I've read that now, thanks.
I noticed that the V+ and GND pins are turned with respect to what is stated on the data sheet,
what do you think about that? Will I risk to burn the sensor in case I try to connect that way?
In case there's no problem buying another one, but it takes time to arrive..
You had VDD on the ground side it shows in your Picture it's some times misleading
how the pin are like the 2n7000 some show bottom up pin side and some show top down
