ESP32 / ESP8266 (NODEMCU) arduino based r2 relay switching on off with Sim800L having 2g GPRS internet -- 2


Sim800L EVB (with internet SIM)

2 ch RELAY TO BE USED FROM ANYWHERE TH INTERNET using a website hosted on server

Authorized numbers stored in sim card can Switch ON OFF Relay using GPRS or th AP / STATION mode using ESP config (th password and command) by creating webpage so that relays can be operated from anywhere using internet th wifi router GPRS data from sim or by sending SMS

ESP32 / ESP8266 and SIM800L based RELAY SWITCHING On OFF

VIA SMS or Wifi router or GPRS as per availability

1 if Wifi Router Internet is available connect and use relays from local area

2. When wifi internet not available use sim card internet data from anywhere

3 Sending SMS

3 options required

Hardware to be used 1. Esp32 / ESP8266 NodeMCU 2. Sim800L / 900 with working internet and sms pack in sim card


for sms

S11 to switch relay 1 on

S10 to switch relay 1 off

S21 to switch relay 2 on

S20 to switch relay 2 off

for GPRS

I11 to switch relay 1 on

I10 to switch relay 1 off

I21 to switch relay 2 on

I20 to switch relay 2 off

or by using making webpage
