目录ObjectiveThis tutorial will teach you using two temperature sensor, that are LM35 and DS18B20, and use the OLED module to display the temperature. Equipment
First experiment (LM35 temperature sensor)SchematicLM35 and DS18B20 use the same pin connection. OLED IIC connection method:
ProgramLM35 and DS18B20 use the same program. Refer to MicroduinoOLEDThermometerLM35-DS18B20.ino
DebugStep 1:Copy the code to IDE and compile it Step 2:Set up the circuit, as follows: Step 3:Download the program and then run it. Step 4:Observe the OLED module. Find a hot object to close the temperature sensor, the OLED will display the value.
ResultAfter LM35 sensor near the heat source, the OLED displayed value will rise, leave the heat source temperature will gradually reduce.
Experiment (DS18B20 temperature)SchematicLM35 and DS18B20 use the same pin connection. OLED IIC connection method:
ProgramLM35 and DS18B20 use the same program. Refers to MicroduinoOLEDThermometerLM35-DS18B20.ino
DebugStep 1:Copy the code to IDE and compile it Step 2:Set up the circuit, as follows: Step 3:Download the program and then run it. Step 4:Observe the OLED. Find a hot object to close the temperature sensor, the digital tube will display the value. ResultAfter DS18B20 sensor near the heat source, the digital tube displayed value will rise, leave the heat source temperature will gradually reduce. Video |
