Ligne 14 :
Ligne 14 : + + − − We have used a widely available analog temperature sensor called {{pl|59|TMP36}} from Analog Devices, and is the temperature sensor that comes with your Spark Maker Kit! You can [http://www.analog.com/en/mems-sensors/digital-temperature-sensors/tmp36/products/product.html download the datasheet] here.

Notice how we are powering the sensor from 3.3V* pin instead of the regular 3.3V. This is because the 3.3V* pin gives out a (LC) clean filtered voltage, ideal for analog applications like these. If the readings you get are noisy or inconsistent, add a 0.01uF (10nF) ceramic capacitor between the analog input pin (in this case, A7) and GND as shown in the set up. Ideally, the sensor should be placed away from the Core so that the heat dissipated by the Core does not affect the temperature readings.
