A bare LM35 in a 3-pin TO-92 package - no board, no support parts. Its output sits at exactly 10.0 mV per degree Celsius with no offset to subtract and no calibration to do, so analogRead times a constant is your temperature. Typically accurate to a quarter of a degree at room temperature, it runs on 4 to 30V, draws under 60 microamps and barely self-heats.
Key features
- 10.0 mV per degree C, no offset, no calibration
- Typically plus or minus 0.25 degrees C at room temperature
- Runs on 4V to 30V, draws under 60 microamps
- Self-heating under 0.1 degrees C in still air
- Bare TO-92 component - three legs, wire it yourself
- Reads below 0 degrees C only with an extra pull-down resistor
