mq-02 detect smoke and alert to mobile app
mq-02 detect smoke and alert to mobile app ,then the sound level from buzzer and the brightness from led 10mm depend on the level of volt which receive value from map funciton of arudino , the arduino reading from MQ2 sensor respectively
mobile app receive value form bluetooth,display a sensor value if a value more than a threshold value then sound and vibration with red color of text box.you can take picture for a hazard place.
thanks for watchiing.

ESP8266-12F w/ WebConfig and Control Page , display and Alarm Sound on ...
ESP8266-12F w/ WebConfig and Control Page + PIR Motion (HC-SR501) , display and Alarm Sound on the Web Browser(PC, Mobile)
Demonstration(Short example clip , what it can do)
***Sorry, Details of Code and Hardware Wire will be shown as soon,Thanks
***ESP8266-12F + PIR Motion (HC-SR501) , display and Alarm Sound on the Web Browser(PC, Mobile)
***Sorry, Details of Code and Hardware Wire will be shown as soon,Thanks
- Alarm Security with Pir Sensor (HC-SR501)
Display and send audio detection via web browser (here using Google Chrome Version 58.0.3029.110 (64-bit))
-WebConfig for setting ssid,pwd , select fixed ip or dynamic ip given from the router
-Timer system for on/off the motion detect system and on/off the electric device via the relays. (it has 2 relays )
-display temperature in Celceius degree.
-can setting the timer via the web or the OLED + Keypad4x4
-can to apply for other for related fields.
***Main Devices List
-ESP8266-12E, ESP8266-12F + PCB Adaptor for esp8266-12e
-Alarm Security with Pir Sensor (HC-SR501)
-DS3231 RTC module
-OLED 0.96" 128x64px
-Matrix Keypad4x4
-PCF8574AT IO expender x 2
-Active Buzzer 5vdc
-Relays 2 channel with opto-isolate
-2 LED 5mm
-NPN 2N2222 x 2
-NPN BC547 x 2
- R, C
**Related Clip
-Assemble parts together and flashing fw. Esp8266-12e,12f + PCB ADAPTER + XC6206P Regulator
https://youtu.be/GJLV1nkl-UU
-Timer system with nodeMCU (Turn on/off the power by setting the timer) , 2 periods timer / an relay
https://youtu.be/JHD-qtlMAlQ
-nodeMCU v2 +Keypad 4x4 + PCF8574AT( io expender), use 2 wires only.
https://youtu.be/lDhUqzp4410
คลิปทดสอบตัวอย่างสั้นๆ Alarm Security with Pir Sensor
- ระบบตรวจจับความเคลื่อนไหว PIR Motion Sensor Module (HC-SR501) + ESP8266-12F(esp-12f) แสดงผลและส่งเสียงการตรวจจับ ผ่านหน้า Web browser (ในที่นี้ ใช้ Google Chrome Version 58.0.3029.110 (64-bit))
- web config สำหรับ กำหนดค่า ssid,pwd เลือกโหมด รับ ip หรือ fix ip addr
- ตั้งเวลา on/off สำหรับ motion detect และหรือควบคุมอุปกรณ์ไฟฟ้าอื่นๆผ่านรีเลย์สวิทย์
-แสดงผล อุณหภูมิ
-สามารถตั้งเวลา Timer system ผ่านทางเวป หรือ ผ่านทาง จอ OLED+Keypad4x4
-ฟังกชั่นอื่นๆ เช่น เปิดปิดหน้าจอ OLED , on/off ,DateTime,Timer system อื่นๆ ผ่านทาง OLED+Keypad
-สามารถนำไปประยุกต์การใช้งานอื่นๆได้ตามสมควร
**รายละเอียด Code และ Hardware Wire จะทำมาแสดงในไม่ช้า ขอบคุณครับ

Assemble parts together and flashing fw. Esp8266-12e,12f + PCB ADAPTER +
XC6206P Regulator
***sorry , for cc(closed caption ) as soon.
-รวมชุด esp8266-12e,12f เข้ากับ pcb adaptor (กรณี Vcc=5v ติดตั้ง ldo regulator แปลงเป็น 3.3v) สุดท้ายจะทำการ flash firmware ด้วย
-flash ด้วย
1. ft232rl (usb to ttl) สำหรับ Vcc 3.3v (กรณี esp ไม่มี ldo regulator) และ 5v( esp82266 ที่มี ldo regulator)
2. witty cloud mini nodemcu ใช้ power supply board ของ witty clound มาใช้ flash firmware ให้กับ esp82266 ที่มี ldo regulator
This clip is about:
-How to flash esp8266 firmware.
-How to flash esp8266 12e.
-Assemble part together an Esp8266 module , PCB ADAPTER and XC6206P Regulator.
-Flash with usng ft232rl(for Vcc of esp 3.3v /5v).
-Flash with Witty Cloud power supply board(for Vcc of esp 5v).
Note. This adapter but not soldered or any additional wires for pin CH_PD ,GPIO15 if you want.
This adapter existed
1. CH_PD is pulled to Vcc by 10k resistor (so module start working after You provide Vcc).
2. GPIO15 is pulled down to GND by 10k resistor.
So to burn new flash image just connect GPIO0 to GND during start.

ref. http://th.element14.com/torex/xc6206p332pr/v-reg-ldo-0-25a-3-3v-smd-sot-89/dp/8796998
TOREX XC6206P332PR Fixed LDO Voltage Regulator, 1.8V to 6V, 250mV Dropout, 3.3Vout, 200mAout,
SOT-89-3
The XC6206P332PR (linear ,low dropout-regulator) is a 3-terminal highly precise low power consumption
Positive Voltage Regulator manufactured using CMOS and laser trimming technologies. The XC6206 series
provides large currents with a significantly small dropout voltage. The XC6206 consists of a current limiter circuit, a
driver transistor, a precision reference voltage and an error correction circuit. The series is compatible with low ESR
ceramic capacitors. The current limiter's foldback circuit operates as a short circuit protection as well as the output
current limiter for the output pin. Output voltages are internally by laser trimming technologies. It is selectable in
0.1V increments within a range of 1.2 to 5.0V.
ref. https://nettigo.eu/products/pcb-adapter-for-esp8266-modules
PCB ADAPTER FOR ESP8266 MODULES
Adapter is for ESP8266 -07 and -12. Version
Modules -07 and -12 are in format not ready to plug in breadboard. When You solder module onto this adapter You
plug it directly into breadboard or use standard F-M wires to get access to all GPIO on board.
Adapter has pin CH_PD pulled up to Vcc, so after You supply Vcc, ESP starts without any additional wires.
This adapter makes working with ESP8266 much easier. CH_PD is pulled to Vcc by 10k resistor (so module start
working after You provide Vcc). GPIO15 is pulled down to GND by 10k resistor, so to burn new flash image just
connect GPIO0 to GND during start.
Wrong silkscreen on adapter/module
Depending on production batch some -07 and -12 modules have replaced GPIO4 and GPIO5. Before You solder in
ESP module check if silkscreen on adapter is correct to avoid errors later. You can take picture of bottom side of
ESP module (there are GPIOs described).

Inter-Integrated Circuit or I2C Between Two arduinos uno
Inter-Integrated Circuit or I2C Between Two arduinos uno
Working:
when pressed a tact switch on the sender board(uno) ,then send data to the receiver board(uno) which communicate via I2C
the receiver board(uno) will display the reCceivered data on the LCD.
Arudino uno
sender ----- receiver
SDA(A4) ----- SDA(A4)
SCL(A5) ----- SCL(A5)
GND ----- GND ***
