Measure the temperature with the LM35 analog temperature sensor - one of the most used in the world
This is a Temperature Sensor based on LM35. The LM35 is a small chip used with Arduino (5V logic) and 3.3V logic microcontrolers. This analog sensor is used to detect ambient air temperature and offers an output voltage proportional to temperature. As it has a good good linearity and high sensitivity, this sensor is really great for learning.
The LM35 (National Semiconductor) can be used in the range 0 to 100 °C and it output 10mV per degree Celsius. Do not place it in the deep freeze or under the oven.
It is a really common measurement sensors is well known in the Arduino world (as popular as the TMP36). Its high sensibility is great for testing and the project requiring fast reaction but sometime it is also a pitfall. Temperature regulation project will requires some inertial reaction when temperature changes (the TMP36 will be more appropriate in that case).
The Gravity IO expansion shield for Arduino is the best match for use this sensor. As this sensor can work at 3.3V it can also be used with MicroPython, Raspberry Pi, intel edison, joule and curie nano.
Using this sensor is easy, connect the black wire to the ground, connect the red wire to the power supply (3.3V or 5V depending on the microcontroler used) and the blue wire to a microcontroler's analog input.
For each order, you will receive a LM35 module and an analog cable.
