Ttgo-Tcall Relay Modül
I designed this circuit for my own garden. The purpose of the circuit is to remotely turn on and off the connected system, and to perform events such as working in the desired time interval and time. As an extra, it is to learn the temperature and humidity in the environment thanks to the dht11 sensor. Thanks to the Ttgo T-call module, which performs the main operations in the circuit, remote control can be provided via internet, call and sms.
Thanks to 4 relays added to the circuit, it is possible to remotely control 4 different devices at the same time.
The relays are electrically disconnected from the circuit with an optacoupler to protect the circuit against any failure.
Since I do not use the circuit commercially, I control it myself thanks to the blynk software. It is also possible to control with dtmf and sms.
