- Industrial temperature sensing and over-temperature protection
- Raspberry Pi GPIO temperature measurement
Arduino Example Formula
float voltage = analogRead(A0) * (5.0 / 1023.0);float tempC = (voltage - 0.5) * 100.0;
FAQ
Q: What’s the difference between TMP36 and TMP36GT9Z?
A: TMP36GT9Z is the TO-92 tape-and-reel variant. Electrically identical to TMP36GRT9Z (SOT-23) and TMP36GZ (TO-92 bulk).
Q: Can I use TMP36 with a 3.3V Arduino?
A: Yes — supply with 3.3V and use AREF = 3.3V in your sketch for accurate readings.
