Arduino DHT11 TM1637 display
Measure the temperature with the DHT11 sensor and display it on a TM1637 display with 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 a TM1637 display with Arduino.
Necessary components
- Arduino UNO
- DTH11 sensor
- TM1637 display
- test plate
- connecting wires
Mounting
To make the assembly, we can connect :
- DATA pin of DTH11 sensor to pin 1 of Arduino
- VCC pin of DTH11 sensor to 3,3 V pin of Arduino.
- GND pin of DTH11 sensor to GND pin of Arduino.
- DIO pin of TM1637 display to pin 3 of Arduino
- CLK pin of TM1637 display to pin 2 of Arduino
- VCC pin of TM1637 display to 3.3V pin of Arduino
- GND pin of TM1637 to GND pin of Arduino
Program
Here is the program that reads the temperature measured by the DTH11 sensor and displays it on a TM1637 display:
