<h3><span id="purpose-of-this-site">Purpose of this site</span></h3><ul>
<li>About the hardware and software of the IOT House that has been under development for many years</li>
<li>Computers, peripherals, networks, and IT fairy tales that you have experienced so far</li>
<li><b> I hope it will be a hint for an environment where parents can compliment and raise their children. </b><ul>
<li><font color="green"> Practical use of things that children have learned from experiments and play-> Parents are pleased-> Parents praise children-> Children learn more and devise to get praise-> Parents children Compliment-> Children grow up-> Society grows up </font></li>

<li>kujiranodanna: A long time ago 1970s Computer peripherals and network equipment maintenance, network engineers, part-time lecturers at IT vocational schools, part-time lecturers at universities (information basics), building management in recent years</li>
<li>People who develop and practice IOT house using Raspberry Pi or old PC and Linux</li>
</ul>
<h3><span id="what-is-practical-iot-house">What is Practical IOT House?</span></h3><ul>
<li>It is a home appliance automation, crime prevention, disaster prevention, voice response, monitoring and control system.</li>
<li>It is built with shell script, C, javascript and can be operated with a browser.<ul>
<li>Check the room temperature from the outside and operate the cooler</li>
<li>Turn on the lights of the entrance and room when it gets dark outside in the evening</li>
<li>Watering the vegetable garden at dawn based on the outside humidity</li>
<li>Email a video when the security sensor works</li>
<li>Play music at a fixed time</li>
<li>Notify by e-mail and phone (wangiri) when the fire detector issues a report</li>
<li>The underfloor ventilation fan is operated intermittently based on the outside air humidity.</li>
</ul>
</li>
<li>Introduced additional Homebridge Alexa, voice and remote control of home appliances with Alexa app</li>
<li>Let’s realize home electronics & home security with Raspberry Pi that is stowed in the back of the desk</li>

<li><p>epicon is a Linux serial communication software.</p>
</li>
<li><p>In practice IOT House uses the thermo-hygrometer AM2321 sensor and AI/DIO for control with TOCOS TWE-Lite via serial communication from the USB connection ToCoStick of Raspberry Pi.</p>
</li>
<li><p>I think that network devices such as Switch and Router that can be configured with serial ports and console PCs can be used regardless of manufacturer or model.</p>
</li>
<li><p>When automating the settings, Cisco Switch and Router copy and paste the text data created in advance and fill in the config.<br>At this time, it is important to send delay of characters and line breaks to prevent the config data from being missed.</p>
</li>
<li><p>epicon supports the transmission delay of important characters and line breaks as this serial console, and you can copy and paste the config with confidence.</p>
</li>
<li><p>In addition, file transfer software such as simple telnet and zmodem, shell, macro, start of external software, etc. CUI, but it is multifunctional and compact.</p>

<li><p>When the BME680 sensor is connected, the gas resistance value is 50 counts every 5 minutes from the <code>2021/02/04/17:22: 23,10.2,43.0,1018.9,3436</code> value created by pepobme680. Based on the average value of 80%, temperature of 10%, and humidity of 10%, the following air quality: IAQ (indoor air quality) is calculated and added.</p>
</li>
<li><p>IAQ is Sample 0(Good) to 500(Hazardous) Temperature(17-28℃):10% Humidity(40-70%):10% Gas(Gas±Gas_base/Gas_base):80%</p>
