ESP8266 WiFi 릴레이 모듈
(ESP8266 WiFi Relay Module)
개요
- 본 제품은 1채널 릴레이와 ESP8266 Serial WiFi 모듈이 결합된 제품입니다.
- WiFi 네트워크 상에서 릴레이를 제어하고자 할 경우에 사용이 가능합니다.
- 250VAC 혹은 30VDC의 부하를 스위칭할 수 있습니다.
- 모듈에는 LED가 장착되어 모듈의 상태를 표시하는데, 빨강 LED는 IN 핀에 신호가 들어올경우 켜집니다.
- 릴레이는 ESP8266을 통해 제어가 되고, 이를 위해서는 UART를 통해서 먼저 ESP8266을 설정하는 것이 필요합니다.
특징
- Size: 45*28mm
The board function description:
IN +,IN-: 5 v power input;
TX ,RX and GND: a serial port debug pins;
Introduction:
Onboard the ESP8266 WIFI module has three work modes: STA (client), AP (hot), the STA + Ap( hot +client), according to the workings of a module to the corresponding choice of WIFI module working mode.Module need before use serial debugging software and USB to TTL module send serial command was carried out on the WIFI module configuration (don't power outages after configuration is complete, as some of the parameters of WIFI module cannot be saved when the power is cut off), mobile phone and WIFI module after establishing a network connection can use the phone APP control relay. - Onboard ESP8266 WIFI module, AP mode 5 client can be connected at the same time;
Module has two work modes: 1, cell phones, carry on the WiFi module;2, mobile phone and WiFI module
Carrying on the same router, by mobile phone APP to control relay;
Transmission distance:
1.The open environment, the mobile phone when carrying on the WIFI module maximum transmission distance of 400 m;
2.When the WiFI module and cell phone carrying on the router at the same time the signal transmission distance in accordance with the router On the weak;
Onboard 5 v, 10 A / 250 v AC 10 A / 30 v DC relay, absorb 100000 times continuously;
Module with diode effusion protection, short response time;
Module baud rate: 9600,8,1,0,0.
