<br>
== Description == 
DS18B20 Temperature Module is one of the most commonly used components for setting the smart home when we are doing the Internet of Things.<br>
For wireless control, we specially designed this ESP-01 DS18B20 Temperature module. 
The DS18B20 Temperature module is equipped with an ESP8266-01 Wifi module, which can access to the wireless network.<br>
You can remote control any other devices according to the temperature data measured by the DS18B20 module.
<br>
<br>
For simple use, we provide our own compiled firmware, the firmware is server mode. The specific information are as follows: <br>
*'''Module working mode:''' <br>

== Use Methods ==
=== 1. Burn the Firmware ===
We have already burned the firmware in the ESP8266-01 WIFI module. And you can re-burn the firmware by yourself as well.  <br>
The programming method is as follows:  <br>
'''<big>①</big>''' Plug the ESP8266 WIFI module onto the keyestudio USB to ESP-01S Wifi shield, and push the shield’s button to '''Uart Download''' end. Then can directly connect them to your computer’s USB port.  <br>
<br>[[File:Ks0408-图片3.png|600px|frameless|thumb]] <br>

<br>
'''<big>②</big>''' Double click to open '''FLASH_DOWNLOAD_TOOL''', as shown in the figure below, uploading the firmware.  <br>
You will see the interface window below.  <br>
<br>[[File:Ks0408-图片4.png|600px|frameless|thumb]] <br>
<br>[[File:0339图片49.png|600px|frameless|thumb]] <br> 
<br>
Then open the ESP8266 Download Tool. <br>
For SPIDownload, open the corresponding file. As shown below. <br>

<br>
<br>
=== 2.Station Mode Operation ===
Because the station_server IP is automatically assigned by the router, so need to read the IP from the serial port. For example: <br>
'''<big>①</big>''' Set the SSID of the home Wifi to: KeyesWifi_S and password is KeyesWifi   <br> <span style=color:red>(note here should set your own home wifi) </span><br>
<br>
'''<big>②</big>''' Directly connect the keyestudio USB to ESP-01S Wifi shield to your computer’s USB port. Then push the shield’s button to '''Flash Boot''' side. <br>
<br>[[File:Ks0408-图片10.png|500px|frameless|thumb]] <br>
<br>
'''<big>③</big>''' Open the PUTTY software on your computer. Below is the example figure we operate. <br>
<br>[[File:Ks0408-图片11.png|600px|frameless|thumb]] <br>
<br>
Double-click the icon of PUTTY software, pop up the interface window below.
<br>[[File:Ks0408-图片12.png|800px|frameless|thumb]] <br>
<br>
After Click Open, plug the ESP8266 WIFI module into keyestudio USB to ESP-01S Wifi shield. <br>
<span style=color:red> Note must click '''Open''' first, then plug the ESP8266 WIFI module into keyestudio USB to ESP-01S Wifi shield. Or else it is invalid. </span><br>
<br>[[File:Ks0408-图片13.png|600px|frameless|thumb]] <br>

<br>
'''<big>④</big>''' The PUTTY terminal will print the message showed below. IP read success! <br>
<br>[[File:Ks0410-图片4.png|600px|frameless|thumb]] <br>
<br>
From the figure, remember your IP name, here is '''192.168.3.13'''  <br>
<br>
<br>
'''<big>⑤</big>'''　The computer and the home wifi are in the same LAN, and the network segment is the same. Connect your computer to your home WiFi. For example, here we use: '''SSID: KeyesWifi_S  ;  Password: KeyesWifi'''     <br>

<br>
'''<big>⑥</big>'''　Plug the ESP8266-01 WIFI module into the DS18B20 Temperature module and access to 3.3V power supply. <br>
<br>[[File:Ks0409-图片5.png|600px|frameless|thumb]] <br>

<br>
'''<big>⑦</big>''' Open the network debugging assistant software, as shown below. <br>
<br>[[File:Ks0408-图片15.png|600px|frameless|thumb]] <br>
<br>[[File:Ks0410-图片5.png|600px|frameless|thumb]] <br>
   
<br>
'''<big>⑧</big>''' Send '''PIN02=DS18B20''', print out the temperature data of current environment.<br>
<br>[[File:Ks0410-图片6.png|600px|frameless|thumb]] <br>
<br>
<span style=color:red> Note that the data tested at the first time may be not accurate; it becomes accurate after the second time.</span><br>   
For the Station mode operation, the test is finished!<br>

<br>
<br>
=== 3.Softap Mode Operation ===
<br>
'''<big>①</big>'''　The computer and the home wifi are in the same LAN, and the network segment is the same. <span style=color:red> Change your home wifi name to avoid wifi module automatic connected. </span><br>
<br>
'''<big>②</big>'''　Connect your computer to your home WiFi. For example, here we use: '''SSID: KeyesWifi_A  ;  Password: KeyesWifi'''   <br>
<br>
'''<big>③</big>''' Plug the ESP8266-01 WIFI module into the DS18B20 Temperature module and access to 3.3V power supply and wait for 20 seconds.<br>
<br>[[File:Ks0409-图片5.png|600px|frameless|thumb]] <br>
<br>
'''<big>④</big>'''　Open the network debugging assistant software, as shown below.<br>
<br>[[File:Ks0408-图片15.png|600px|frameless|thumb]] <br>
<br>[[File:Ks0410-图片7.png|600px|frameless|thumb]] <br>
<br>
'''<big>⑤</big>'''　Send '''PIN02=DS18B20''', print out the temperature data of current environment.<br>
<br>[[File:Ks0410-图片8.png|600px|frameless|thumb]] <br>
<br>
<span style=color:red> Note that the data tested at the first time may be not accurate; it becomes accurate after the second time.</span><br>   
For the Softap mode operation, the test is finished! <br>
