ESP32-WROOM 230V 1Ch 10A Wifi Relæ Module

ESP32-WROOM 230V 1Ch 10A Wifi Relæ Module har en indgangs spænding på 230V, og bliver kontrolleret fra ESP32-WROOM chippen. Perfekt til alle IoT projekter.

Tekniske detaljer:

AC powered esp32 WiFi Bluetooth ble single relay module esp32 development board 1, onboard mature and stable esp32-wroom-32e module, large capacity 4m byte flash;
2. The I / O port and UART program download port of esp32 module are all led out to facilitate secondary development;
3. On board AC-DC switching power supply module, the power supply mode supports AC90-250V;
4. RST reset key and IO0 programmable key of onboard esp32 module;
5. Esp32 supports the use of Arduino ide development tools and provides reference programs under the Arduino development environment;
6. On board 1-way 5V relay, output switch signal, suitable for controlling loads with working voltage within AC 250V / dc30v;
7. On board power indicator, 1 programmable led and relay indicator.

Installere ESP package (Arduino IDE)

• Åben Arduino IDE (Download her)
• Klik “Fil/Egenskaber”
• Indtast dette link i feltet “Additionel Board Manager URL’s”
• Link “https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json“
• Klik OK
• Åben “Værktøj/Board/Boards manager” (Lad programmet opdatere)
• Find “ESP32” og installere
• Klik derefter “Værktøj/Board” og find (DOIT ESP32 DEVKIT V1)
• “Værktøj/Programmer” skal være “AVR ISP”
• Du er nu klar til at sende en kode

Program Upload: (Arduino IDE)
Da dette modul ikke har en USB interface, skal der bruges en “TTL Serial Adapter Module” som sender programmet over i chippen. Du kan købe den her:

• FT232RL FTDI USB 2.0 to TTL Serial Adapter Module

Inden koden kan uploades skal IO0 forbindes til GND imens koden uploades.

Relay output:
NC: normally closed end, the relay is short circuited with com before closing and suspended after closing.
COM: public end.
No: normal opened end, the relay is suspended before closing, and it is short circuited with com after closing.
