What is the best temperature sensor for Arduino?

DHT11 is the most popular temperature and humidity module for Arduino and Raspberry Pi due to its many advantages. E.g. Low power consumption and excellent long-term stability. Relatively high measurement accuracy can be obtained at a very low cost.

How to use 433MHz RF transmitter and receiver with Arduino?

Receiver Section Wiring

The wiring for the receiver is just as easy as the transmitter. Once again there are only three connections to make. Connect the VCC pin to 5V pin and GND to ground on the Arduino. Any of the middle two Data-Out pins should be connected to digital pin 11 as shown in the figure.

Does Arduino have built in temperature sensor?

The temperature sensor in Arduino converts the surrounding temperature to voltage. It further converts the voltage to Celcius, Celcius to Fahrenheit, and prints the Fahrenheit temperature on the LCD screen.
