Arduino, Smart Home Sonoff

SONOFF DUALR2 is a WiFi based 2-gang switch that can independently connect and control two connected devices or lights - this simply means that 1 SONOFF DUALR2 control switch is equivalent to 2 Sonoff basic switches!

Sonoff 433 MHz wireless remote control 4 buttons (IM160323001) This product can work with our smart home products: SONOFF RFR2, SONOFF SlampherR2, SONOFF 4CHPROR3, SONOFF RF Bridge 433, SONOFF TX.

Sonoff RE5V1C Wi-Fi relay switch (IM171018005) has nano size and dry contact output.

Sonoff products will transform your ordinary home into a smart home that is controlled via an internet-connected phone.

SONOFF TH Elite is an ESP32-based temperature and humidity monitoring smart switch.

SONOFF POW Elite 16A is a power meter switch with a newly upgraded ESP32 chip that is 200% faster than the previous ESP8622 chip. With an LCD display, you can track the real-time power, current and voltage of your appliances and the accumulated power consumption. 

Sonoff ZBMINI-L is a universal switch controlled by ZigBee. It works with 240V voltage and enables control of any device anywhere in the world, controlling it by your mobile phone or voice assistants such as Alexa. Thanks to its small size it fits in most power supplies. No neutral wire required.

SPM-4Relay - stackable power meter (slave) realizes smart management with overload protection, metadata monitoring and electricity statistics. Up to 32 SPM-4Relays can be connected to one SPM-Main. Each SPM-4Relay has 4 isolated channels for better device management. You can monitor power consumption using the eWeLink app on your mobile phone. Each channel supports a maximum current of 20A. The SPM-Main communicates with the SPM-4Relays via RS-485, allowing multi-terminal and stable data transmission over long distances. It comes with overload protection to protect from burning out.

Arduino Mega 2560 R3  A000067 has been designed with larger and more ambitious projects in mind. It has 54 digital input / output pins (15 of which can be used as PWM outputs), 16 analog inputs, 4 UART (i.e. hardware serial ports). The large number of analog and digital pins, along with larger MEMORY, make the Mega 2560 ideal for devices such as 3D printers and other demanding applications. The Mega 2560 board is compatible with most shields designed for Arduino Uno.

Arduino UNO is the best board to start your experience with electronics and programming. If this is your first experience with the platform, UNO is the most robust board you can start with. UNO is the most widely used and documented board in the entire Arduino family. Its power ensures ATmega 328p microcontroller, the board is equipped with 14 digital pins, and 6 analog
