== About the TMP36 Sensor ==
The TMP36 is the reference analogue temperature sensor in the Arduino world. It is affordable, small et power efficient. For sure there are better temperature sensors but this one will do the job for almost nothing :-)
This sensor is very common and easy to use. It is also one of the components of the {{pl|11|ARDX development kit}}.
With the TMP36, it is possible to measure a temperature from -50°C to 125°C, the output voltage is proportional to the temperature.
Don't be fooled, the TMP36 looks like a transistor (eg: P2N2222AG) but it isn't a transistor. It is a complex sensor within a package identical to a transistor.
There are 3 pins on the TMP36.
* the '''ground''' (on the left),
* the '''output''' signal (center position),
* the '''+5 volts''' (on the right)
[[Fichier:TMP36-pinout.jpg]]
The sensor output signal does output 10 millivolts per degree (with 500mV offset for temperature under 0°C).
Eg:
* 25° C --> output = 750 mV
* 0° C --> output = 500mV
=== Technical details ===
Pour l'utiliser, connectez simplement la broche 1 (gauche) à une source d'alimentation (entre 2.7 et 5.5V), la broche 3 (droite) à la masse (gnd) et finalement la broche 2 (au milieu) sur une entrée analogique de votre microcontroleur.
La tension de sortie est de 0V à -50°C et 1.75V à 125°C. Il est facile de convertir la tension de sortie (en millivolts) en température à l'aide de la formule:
Temp °C = 100*(lecture en V) - 50
La fiche technique du TMP36 est accessible ici.
