Microduino OLED temperature and humidity meter(DHT11, SHT10, AM2321)

Language	English

Objective This tutorial teach you how to use three temperature and humidity sensors, DHT11, SHT10 and AM2321, and use the OLED to display result. Equipment Microduino-Core Microduino-FT232R Microduino-Weatherstation Microduino-OLED Microduino-Cube-S1 Other equipment USB cable Breadboard Jumper Breadboard DHT11 SHT10 First Experiment (DHT11) Schematic 文件:MicroduinoOLED温湿度计原理图(DHT11).jpg 600px Microduino-OLED's wire connects to Microduino-Cube-S1's slot, and then connects to sensor. Program Download program: https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Sensor/OLED_DHT11 Debug Step 1：Download DHTlib library, and uncompress it to the libraries folder of Arduino IDE, and then restart IDE. https://github.com/RobTillaart/Arduino/tree/master/libraries/DHTlib Step 2：Copy code to IDE and compile it. Step 3：Set up circuit, as follows: 文件:MicroduinoOLED温湿度计连接图(DHT11).jpg 600px Step 4：Run program. Step 5：Observe the OLED. Find a hot object to close the temperature sensor or blowing on the sensor, the OLED will display the result. Result After DHT11 sensor near the heat source, the OLED displayed value will rise, leave the heat source temperature will gradually reduce. Blowing on the sensor, the number will rise too. Second Experiment(SHT10) Schematic 文件:MicroduinoOLED温湿度计原理图(SHT10).jpg 600px Microduino-OLED's wire connects to Microduino-Cube-S1's slot, and then connects to sensor. Program Download program: https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Sensor/OLED_SHT10 Debug Step 1：Download SHT10 library, and uncompress it to libraries folder of Arduino IDE, then restart IDE. https://github.com/practicalarduino/SHT1x Step 2：Copy the code to IDE and compile it. Step 3：Set up circuit, as follows: 文件:MicroduinoOLED温湿度计连接图(SHT10).jpg 600px Step 4：Run program. Step 5：Observe the OLED. Find a hot object to close the temperature sensor or blowing on the sensor, the OLED will display the result. Result After SHT10 sensor near the heat source, the OLED displayed value will rise, leave the heat source temperature will gradually reduce. Blowing on the sensor, the number will rise too. Third Experiment(AM2321) Schematic 文件:MicroduinoOLED温湿度计原理图(AM2321).jpg 600px Program Downlaod program: https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Sensor/OLED_AM2321 Debug Step 1：Download AM2312 library, and uncompress it to libraries folder of Arduino IDE, then restart IDE. https://github.com/wangdong/AM2321 Step 2：Copy the code to IDE and compile it. Step 3：Set up circuit, as follows: 文件:MicroduinoOLED温湿度计连接图(AM2321).jpg 600px Plug in Microduino-Core and Microduino-FT232R to Microduino-Weatherstation's two slots. Step 4：Run program. Step 5：Observe the OLED. Find a hot object to close the temperature sensor or blowing on the sensor, the OLED will display the result. Result After AM2321 sensor near the heat source, the OLED displayed value will rise, leave the heat source temperature will gradually reduce. Blowing on the sensor, the number will rise too. vIDEO OLED temperature and humidity meter(DHT11) ： http://v.youku.com/v_show/id_XNjkyMzQzOTky.html OLED temperature and humidity meter(AM2321) ： http://v.youku.com/v_show/id_XNjkyMzM5Mjg0.html
