ESP12F + One Channel Relay Module for IOT (ESP8266)
This is a One channel WiFi module equipped with an ESP-12F WiFi module (8 bit MCU). This MCU is capable of controlling relay at any time with some simple coding. By using a WiFi relay phone application, the user could control the relays from anywhere in the world as long there is Internet connectivity!
Features:
- Onboard high-quality MCU and ESP-12F WIFI module
- Two working modes:
Mode 1: cellphone carry on wifi module directly
Mode 2: cellphone and wifi module carry on router together
- Additional function: ESP-12 works as a microcontroller when disconnected from the relay module
- Transmission distance:
(1) In the open environment, the mobile phone when carrying on the WIFI module maximum transmission distance of 100 m;
(2) When the WiFI module and cell phone carrying on the router at the same time the signal transmission distance depends on router signal - Use the Smartconfig technology to complete the configuration of the account and password of the esp-12F WIFI module on the mobile APP. The configured account and password will be memorized after power off
- Power:
Logic: 5V, Relays: 10A/250VAC OR 10A/30VDC, Cycles:100,000 times - protection diode for short and fast response time. - With mode option and working statue LED indicator
- With 4 isolator and strong anti-interference ability
- Reserved UART debug interface and MCU download port for program
- Board size: 60*63mm
- IN+, IN-: 5V voltage input
- 5V, GND, TX, RX: UART serial port PIN
- SWIM, PIN8, NRST: reserved MCU download port
- Button S1: change mode, the default mode is mode 1
- Button S2: reset
Control command for relay(hex format):
Open relay 1: A0 01 01 A2
Close relay 1: A0 01 00 A1
Open relay 2: A0 02 01 A3
Close relay 2: A0 02 00 A2
Open relay 3: A0 03 01 A4
Close relay 3: A0 03 00 A3
Open relay 4: A0 04 01 A5
Close relay 4: A0 04 00 A4
