Precise details:
Features:
1. On board esp8266 chip;
2. The module has two working modes
Mode 1: the mobile phone is directly mounted on the esp8266 chip;
Mode 2: the mobile phone and esp8266 chip are carried on the router at the same time;
3. Transmission distance:
(1) In the open environment, when the mobile phone is mounted on the esp8266 chip, the maximum stable transmission distance is 100m;
(2) When esp8266 chip and mobile phone are carried on the router at the same time, the transmission distance depends on the signal strength of the router.
4. The account and password of esp8266 chip can be configured on the mobile app with smart config technology. The configured account and password have the power-off memory function;
5. On board 5V, 10A / 250V AC, 10A / 30V DC relay, which can pull in 100000 times continuously, with diode leakage protection and short response time;
6. On board mode selection indicator;
7. The program download interface of esp8266 chip is reserved.
8. Board size: 44.8 x 41.7mm
9. Weight: 16g
Note:
(1) When the mobile phone is mounted on the WiFi module, the maximum stable transmission distance is 100m.
(2) When WiFi module and mobile phone are carried on the router at the same time, the transmission distance depends on the signal strength of the router.
(3) At present, the module only supports Android system.
Board function description:
Ln +, in -: 5V power input;
5V, TX, Rx, GND, lO0: program download interface; Key S1: short press mode switch, long press 2s to clear password key S2: reset key
Led D4 and D5 (red light): the relay working indicator is on
Led D2 (red light): power indicator
Led D1 (green light): mode indicator, described as follows: (1) mode 1 when off;
(2) When 1s flashes once, it means waiting for mobile app to configure WiFi account and password for ESP 8266 module;
(3) When it is always on, it means that the TCP connection is successfully established with the mobile phone.
COM1: common terminal;
NC1: normally closed end, the relay is short circuited with COM1 before closing and suspended after closing;
NO1: normally open, the relay is suspended before closing, and then it is short circuited with COM1 after closing.
First place: the relay is suspended before closing, and then short circuited with COM1
Com 2: common terminal;
NC2: normally closed end, the relay is short circuited with com2 before closing and suspended after closing;
NO2: normally open, the relay is suspended before closing, and then it is short circuited with com2 after closing.
Normally, the relay is suspended before closing, and then it is short circuited with com 2.
Relay control command (hex form): open the first relay: A0 0101 A2
Close the first relay: A0 01 00 A1, open the second relay: A0 02 01 A3, close the second relay: A0 02 00 A2
Turn off the first relay: A0000 A1, turn on the second relay: A0002001 A3, turn off the second relay: A0002000 A2
2. Prepare the following tools and software before use:
(1) 5V / 1A power adapter, the positive and negative poles of the power supply are connected to the in + and in - of the module respectively;
(2) The app "esotouch DEM" installed on Android mobile terminal is used to configure wifi account and password for esp-01 module when working mode 2 is used for the first time.
Package included:
1 x Relay Module with PIN
