You request the use of a +header file in your project source file (C, C++, etc) located in `src` folder +by including it, with the C preprocessing directive `#include'. + +```src/main.c + +#include "header.h" + +int main (void) +{ + ... +} +``` + +Including a header file produces the same results as copying the header file +into each source file that needs it. Such copying would be time-consuming +and error-prone. With a header file, the related declarations appear +in only one place. If they need to be changed, they can be changed in one +place, and programs that include the header file will automatically use the +new version when next recompiled. The header file eliminates the labor of +finding and changing all the copies as well as the risk that a failure to +find one copy will result in inconsistencies within a program. + +In C, the usual convention is to give header files names that end with `.h'. +It is most portable to use only letters, digits, dashes, and underscores in +header file names, and at most one dot. + +Read more about using header files in official GCC documentation: + +* Include Syntax +* Include Operation +* Once-Only Headers +* Computed Includes + +https://gcc.gnu.org/onlinedocs/cpp/Header-Files.html diff --git a/lib/README b/lib/README new file mode 100644 index 0000000..6debab1 --- /dev/null +++ b/lib/README @@ -0,0 +1,46 @@ + +This directory is intended for project specific (private) libraries. +PlatformIO will compile them to static libraries and link into executable file. + +The source code of each library should be placed in a an own separate directory +("lib/your_library_name/[here are source files]"). + +For example, see a structure of the following two libraries `Foo` and `Bar`: + +|--lib +| | +| |--Bar +| | |--docs +| | |--examples +| | |--src +| | |- Bar.c +| | |- Bar.h +| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html +| | +| |--Foo +| | |- Foo.c +| | |- Foo.h +| | +| |- README --> THIS FILE +| +|- platformio.ini +|--src + |- main.c + +and a contents of `src/main.c`: +``` +#include +#include + +int main (void) +{ + ... +} + +``` + +PlatformIO Library Dependency Finder will find automatically dependent +libraries scanning project source files. + +More information about PlatformIO Library Dependency Finder +- https://docs.platformio.org/page/librarymanager/ldf.html diff --git a/platformio.ini b/platformio.ini new file mode 100644 index 0000000..86a16e7 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,18 @@ +; PlatformIO Project Configuration File +; +; Build options: build flags, source filter +; Upload options: custom upload port, speed and extra flags +; Library options: dependencies, extra library storages +; Advanced options: extra scripting +; +; Please visit documentation for the other options and examples +; https://docs.platformio.org/page/projectconf.html + +[env:d1_mini] +platform = espressif8266 +board = d1_mini +framework = arduino +lib_deps = mobizt/ESP Mail Client @ ^1.1.7 + arduino-libraries/NTPClient @ ^3.2.1 + https://github.com/enjoyneering/AHTxx @ ^1.1.5 +monitor_speed = 115200 diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..1830d3c --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,100 @@ +#include +#include +#include +#include +#include + +#define ALARM_TEMP 85.0 +#define LOCATION "server room" + +#define HOSTNAME "tempmon" +#define SSID "ncc74656" +#define PSK "Rw7qfY5tmtaWbXaWQ5aMSRkF" + +#define SMTP_HOST "alfter.us" +#define SMTP_PORT 587 +#define SMTP_SENDER "salfter" +#define SMTP_PASSWD "4zD7tistzCEElgwj" +#define SENDER_NAME "Temperature Monitor" +#define SENDER_EMAIL "tempmon@alfter.us" +const String mail_recips[][2]={ + {"Scott Alfter", "scott@alfter.us"}, + {"Pushover client", "vsr61ekz1e@pomail.net"} +}; +#define mail_recips_len 2 + +#define I2C_SDA D3 +#define I2C_SCL D4 + +SMTPSession smtp; + +float ahtValue; +AHTxx aht10(AHTXX_ADDRESS_X38, AHT1x_SENSOR); + +void setup() +{ + Serial.begin(115200); + + // set up sensor + while (aht10.begin(I2C_SDA, I2C_SCL)!=true) + { + Serial.println("waiting for sensor"); + delay(2000); + } + + // connect to network + WiFi.hostname(HOSTNAME); + WiFi.begin(SSID, PSK); + while (WiFi.status()!=WL_CONNECTED) + delay(500); + Serial.println("connected to WiFi"); +} + +bool active=false; +void loop() +{ + ahtValue=aht10.readTemperature(); + if (ahtValue!=AHTXX_ERROR) + { + Serial.print("temp="); + Serial.print(ahtValue/5.0*9.0+32.0); + Serial.println("F"); + if (ahtValue/5.0*9.0+32.0>=ALARM_TEMP && !active) + { + active=true; // don't spam + + // send mail + ESP_Mail_Session session; + session.server.host_name=SMTP_HOST; + session.server.port=SMTP_PORT; + session.login.email=SMTP_SENDER; + session.login.password=SMTP_PASSWD; + session.login.user_domain=""; + session.time.ntp_server="us.pool.ntp.org"; + session.time.gmt_offset=0; + session.time.day_light_offset=0; + + SMTP_Message msg; + msg.sender.name=SENDER_NAME; + msg.sender.email=SENDER_EMAIL; + msg.subject=(String)LOCATION+(String)" temperature too high: "+(String)(ahtValue/5.0*9.0+32.0); + for (int i=0; i
