Full description
The TMP36 is one of the easiest ways to measure temperature in your electronics projects. It outputs an analog voltage that scales linearly at 10mV per degree Celsius, so a single analogRead() and one line of math give you the temperature - no lookup tables, libraries or calibration required.
It operates from 2.7V to 5.5V, draws less than 50µA, and covers -40°C to +125°C, making it ideal for weather stations, thermostats, battery-powered loggers and classroom experiments. The TO-92 package plugs straight into a breadboard.
Pinout: flat face toward you - left pin V+, middle pin Vout, right pin GND.
