Microduino OLED thermometer(LM35, DS18b20)

Language	English

Objective This tutorial will teach you using two temperature sensor, that are LM35 and DS18B20, and use the OLED module to display the temperature. Equipment Microduino-Core Microduino-FT232R Other equipment Breadboard Jumper Breadboard LM35 temperature sensor DS18B20 temperature sensor Microduino OLED USB cable First experiment (LM35 temperature sensor) Schematic 文件:MicroduinoOLED温度计(LM35,DS18B20)原理图.jpg 600px LM35 and DS18B20 use the same pin connection. OLED IIC connection method: OLED Core Core+ SDA A4 SDA SCL A5 SCL 3V3 3V3 3V3 GND GND GND Program LM35 and DS18B20 use the same program. Refer to MicroduinoOLEDThermometerLM35-DS18B20.ino Debug Step 1：Copy the code to IDE and compile it Step 2：Set up the circuit, as follows: 文件:MicroduinoOLED温度计(LM35, DS18B20)连接图.jpg 600px 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. Result After LM35 sensor near the heat source, the OLED displayed value will rise, leave the heat source temperature will gradually reduce.
