🚀 12.2022 - UPDATE TO BLYNK 2.0 🚀

Project was updated to the new version of Blynk 2.0

To build a project, you need to download all the necessary libraries and create the settings.cpp file in the src folder:

// Project settings
#include "IPAddress.h"

struct Settings
{
    const char *wifiSSID = "YYY";
    const char *wifiPassword = "ZZZ";
    const char *imageUploadScriptUrl = "http://example.com/upload.php";
    const char *version = "2.0.0";
    // IPAddress ip = IPAddress(192, 168, 43, 223);
    // IPAddress gateway = IPAddress(192, 168, 43, 1);
    // IPAddress subnet = IPAddress(255, 255, 255, 0);
};

Features

• measuring the temperature and humidity inside the hive measuring the temperature, humidity and pressure outside the hive
• triggers an alarm (SMS/call/notification) when someone opens the hive - gyroscope sensor
• triggers an alarm (SMS / call / notification) when someone picks up the hive - a magnetic contact sensor
• audio transmission via SMI800L - mobile phone call

Currents list:

• ESP32 WROOM-32
• MMA8452 Triaxial Accelerometer
• SHT30 digital temperature/humidity sensor
• BMP280 digital temperature/humidity/pressure sensor
• SIM 800L module
• MAX4466 microphone
• INA219 sensor
• Magnetic contact sensor
• Solar panel 18V with battery and solar charger or other power supply

Save battery power:

• Set CPU frequency to 30% (80Mhz) - setCpuFrequencyMhz(80);
• Setup lowest WiFi power - WiFi.setTxPower(WIFI_POWER_MINUS_1dBm);
• Setup static IP, Gateway and DNS (quicker WiFi connection) - WiFi.config(settings.ip, settings.gateway, settings.subnet, settings.gateway);
• When disconnect WiFi, turn off WiFi modem - WiFi.disconnect(true);
