Measuring temperature with DHT11 sensor and Arduino

Purpose of this tutorial:

In this tutorial we will see how to read the temperature measured by the DTH11 sensor and display it on an LCD display.

Required components

• Arduino UNO
• sensor DTH11
• LCD display
• connecting wires

Mounting

For the DTH11 sensor, we connect:

• DATA pin of the DTH11 sensor to the digital PIN2 of arduino.
• VCC pin of the DTH11 sensor to the 3.3 V PIN of Arduino.
• GND pin of the DTH11 sensor to the GND of Arduino.

For the LCD display we connect:

• the SDA pin at the Arduino analog pin A4.

• the SCL pin at the Arduino analog pin A5.

• the VCC pin at the Arduino 5v pin.

• the GND pin at the Arduino GND pin
