FIRE ALARM SYSTEM

Title : Fire Alarm System

Theme : IoT ( Internet Of Thing )

Sinopsis

 A fire alarm system has a number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be activated automatically from smoke detectors, and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes which sound an alarm, followed by a voice evacuation message which warns people inside the building not to use the elevators. Fire alarm sounders can be set to certain frequencies and different tones including low, medium and high, depending on the country and manufacturer of the device. Most fire alarm systems in Europe sound like a siren with alternating frequencies. Fire alarm electronic devices are known as horns in the United States and Canada, and can be either continuous or set to different codes. Fire alarm warning devices can also be set to different volume levels. And here I will explain how it works and also the materials for making a fire alarm system.

Tools Required

1. NODEMCU ESP8266

2. Temperature Sensor DHT11

3. Smoke Sensor MQ2

4. USB Cable

5. Jumper Female to Female Cable

Here I use 2 paths, namely the website path and the internet path.

Assembly Line

1. Connect the jumper cable to connect the Nodemcu with the temperature or temperature sensor

2. We further install jumper cable to connect Nodemcu with Smoke / Gas sensor

3. Connect the usb cable to the PC. Then open the arduino application on your PC.

4. Input Nodemcu programming language

5. Finally, i was successful i tested the tool using gas and fire.

Testing Tools

1. We will try the gas sensor first. We have to aim the gas near the gas sensor. We'll wait until the number on the gas sensor goes up and a warning notification appears. Now censored with gas, the number that will make a warning notification appear is 390. And this is an example if the sensor has reached 390 on the gas detector.

2. If we have advanced to the temperature sensor. And this sensor we use the fire as a testing tool. Censored, the web will display a notification when the temperature reaches 35 ° C

That's all the reviews from me. More or less apologize. Thank you

TUTORIAL MEMBUAT NIRMANA DENGAN MUDAH MENGGUNAKAN CORELDRAW

PENGERTIAN NIRMANA

Nirmana berasal dari bahasa Jawa Kuno ( Kawi ) yang artinya "Tanpa angan-angan. Secara arto kata, Nirmana sebagai tidak ada wujud atau tidak ada rupa. Hal ini dimaksudkan bahwa Nirmana dari semula yang tidak ada rupa kemudian berwujud media rupa untuk memperoleh keindahan. Jika diartikan lebih dalam Nirmana berarti lambang-lambang bentuk tidak bermakna.

Nah lalu bagaimana sih cara membuat Nirmana di Coreldraw? Sekarang mari kita lanjut ke tutorialnya
