Story
Introduction - Introduzione
GitHub : https://github.com/albino98/telegram_esp32
ENG
I devised this project to create a smart security system, without the need for external input devices, such as a numeric keypad for alarm activation, etc.
In fact, the project allows you to manage the esp32 directly from your mobile phone or PC via a telegram bot.

To create the project I took inspiration from other projects on the net, such as the following:
https://randomnerdtutorials.com/esp32-cam-take-photo-save-microsd-card/
ITA
Ho ideato questo progetto per creare un sistema di sicurezza smart, senza il bisogno di dispositivi esterni per l’input, come ad esempio un tastierino numerico per l’attivazione dell’allarme, ecc.
Il progetto infatti consente di gestire il l’esp32 direttamente dal cellulare o da pc tramite un bot telegram.

Per creare il progetto ho preso spunto da altri progetti in rete, come ad esempio il seguente:

Components - Componenti
ENG
- ESP32 cam
- PIR
- connection cable
I bought this kit from Amazon: https://www.amazon.it/ideaspark-ESP32-CAM-Istantanea-Riconoscimento-Telecamera/dp/B084H5XNGQ/ref=sr_1_11?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=esp32+kit&qid=1614103288&sr=8-11
The kit already contains the USB2.0 serial cable from USB to TTL PL2303TA needed to program the esp32.

Il kit contiene già il Cavo USB2.0 seriale da USB a TTL PL2303TA necessario per programmare l'esp32.

Connection between the Esp32Cam and the USB to serial cable - Connessione tra l'Esp32Cam e il cavo da USB a seriale
** Connect GPIO 0 and GND ports with DuPont cable as following to load the code - Collega GPIO 0 e GND per caricare il codice sull'ESP. **
** Remember to disconnect the GPIO 0 and GND ports after loading the code and press the reset button on the Esp to execute the code - Ricorda di disconnettere i pin GPIO 0 e GND dopo aver caricato il codice e premere il tasto reset dell'Esp per eseguire il codice. **
Connection between Esp32Cam and PIR - Connessione tra l'Esp32Cam e il sensore di movimento
If ESP32 CAM takes pictures frequently. Or never take a picture. Adjust the rotary buttons on the HC-SR501 Human Infrared Sensor - Se il Pir è troppo sensibile e quindi fa scattare troppe fotografie oppure è troppo poco sensibile, regolalo attraverso i pulsanti rotanti.
About the project
ITA
Questo semplice sistema di sorveglianza domestico ti consente di ricevere una fotografia su telegram non appena viene rilevato un movimento tramite il sensore PIR, di richiedere all’esp32 una foto istantanea, accendere o spegnere il led integrato sull’esp o di armare e disarmare il sensore PIR. Il tutto tramite dei semplici comandi del bot telegram. Per la creazione del bot telegram ci sono molte guide online che spiegano come crearlo partendo dal botFather.
ENG
This simple home surveillance system allows you to receive a photo on telegram when movement is detected via the PIR sensor, to request an instant photo from the esp32, turn on or off the integrated led on the esp or to arm and disarm the PIR sensor.. All through simple commands of the telegram bot. For the creation of the telegram bot there are many online guides that explain how to create it starting from the botFather.
