==Objective==
This lesson will introduce the temperature sensor, combined with Microduino to be a simple thermometer. Digital temperature sensors have a common DS18b20, DHT11, SHT10 and so one. Analog temperature sensor has thermistor, AD590, LM35D so on.

==Equipment==
*'''[[Microduino-Core]]'''
*'''[[Microduino-FT232R]]'''
*Other hardware equipment
**Breadboard Jumper one box
**Breadboard one piece
**LM35D temperature sensor one

==LM35 temperature sensor==
This sensor can measure of 0-100 degrees Celsius temperature, and output the value of voltage. Starting from 0 degrees temperature rise per 1 degree output voltage will increase 10 mv, so that we can use the analog port to detection sensor voltage, after simple to calculate the measured temperature value.
===LM35 connection===

==Experimental schematic==
The connection is very easy,just pay attention to the positive and negative。

==Program==
<source lang="cpp">
void setup() {

Serial.begin(115200); //Set teh baud rate to 115200
}

void loop() {

int n = analogRead(A0); //Read the voltage from A0

float vol = n * (5.0 / 1023.0*100); //Use a float variable to save temperature value which was calculated from voltage.

Serial.println(vol); //Output the temperature from serial

delay(1000); //Wait for 1s for refresh
}
</source>

==Result==
After download, you can see the temperature data from serial monitor, refreshed every 1s.
