Tuya multifunctional alarm

 
Main functions:
1. Collect gas, smoke, temperature, humidity, light intensity, battery power, and human body infrared induction signals from time to time.
2. When any value of gas, smoke, or temperature exceeds the threshold, the buzzer alarm will be activated and the alarm will be alarmed at the same time. The lights start flashing.
3. There are alarm, mute and alarm ring selection switches on the side of the alarm, which can be turned on or off as needed.
4. The alarm also has a human body sensing night light function. When the light becomes weak and someone is moving, the night light will automatically light up, and will automatically turn off after a ten-second delay.
5. The APP adopts Tuya’s custom interface. The homepage can display the status and values ​​of each sensor. Click "Historical Data" at the bottom to view historical curve graphs of gas, smoke, temperature, humidity, and light; the "Alarm Parameter Settings" page can be opened or Turn off the alarm, turn on or off the buzzer, set the alarm duration, alarm ringtone and other parameters; the "Message Push Settings" page can turn on the APP message push function. You can also receive alarm reminders in the mobile phone message bar after exiting the APP. The following is the selection and configuration of the Tuya module
 
in the actual picture : 1. First create the product on the Tuya IoT platform and select "Multi-Function Sensor" 2. Select the corresponding function points as needed. 3. Select the panel. Use the custom panel here to create your own style interface. 4. Select the hardware and download the development materials. Here I chose the Tuya CBU Wi-Fi & Bluetooth module and placed the order after confirming it is correct. 5. The MCU program is written here using ARDUINO IDE. It is relatively simple and easy to use the Tuya_WiFi_MCU_SDK library. 6. After the program is written, you can use the Tuya debugging tool to test the program. PS: This is the work I participated in last year’s graffiti activity. I recently compiled the previous materials and released them for learning and communication with everyone. If the compilation prompts that there is no DHT.H file, you can search for DHT_sensor_library in "Library Management" and install this library to compile it successfully. You can also download the DHT_sensor_library.rar file in the attachment, unzip it and put it in the C:UsersAdministratorDocumentsArduinolibraries folder
