Скачать или смотреть Make a Thermometer using LM35 Analog Temperature Sensor and Arduino UNO R3

In this video we have discussed about LM35 ( Analog Temperature sensor), its features, range, accuracy etc. and all important information have been covered along with a simple demonstration of measuring ambient room temperature using Arduino UNO R3.

In the upcoming videos, we will be comparing this sensor LM35 with DHT11( Temperature and humidity sensor) and understand their basic differences.

Key moments:
00:14 LM35 and DHT11 basics
01:53 LM35 pin configuration and sensor connection with Arduino
04:47 LM35 features from datasheet
08:53 Sensor Transfer Function
10:08 Constructing program code
13:05 Adjusting code for temperature calculation
16:36 Modification needed forTMP36

Code:

float temp=0;
void setup() {
pinMode(A0, INPUT);// put your setup code here, to run once:
Serial.begin(9600);
}

void loop() {
temp=analogRead(A0);
Serial.print("Temp: ");
Serial.print(temp*4.9/10);
Serial.println(" C");
delay(1000);
}
