==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-FT232R]]'''
*'''[[Microduino-Weatherstation]]'''
*'''[[Microduino-OLED]]'''
*'''[[Microduino-Cube-S1]]'''

**Breadboard 
**DHT11
**SHT10


==First Experiment (DHT11)==

==Schematic==
[[File:MicroduinoOLED温湿度计原理图(DHT11).jpg|600px|center|thumb]]
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 unzip 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:

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==
[[File:MicroduinoOLED温湿度计原理图(SHT10).jpg|600px|center|thumb]]
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:

[[File:MicroduinoOLED温湿度计连接图(SHT10).jpg|600px|center|thumb]]
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==
[[File:MicroduinoOLED温湿度计原理图(AM2321).jpg|600px|center|thumb]]

==Program==
Download 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:

[[File:MicroduinoOLED温湿度计连接图(AM2321).jpg|600px|center|thumb]]
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.
