Description
Water pump control for irrigation via telegram and esp32
Water Pump Control by Telegram and ESP32 is an automated system that allows you to remotely control a water pump by using an ESP32 microcontroller and the Telegram messaging platform.
The ESP32 is a low-cost, low-power microcontroller that can connect to the Internet using Wi-Fi, making it ideal for IoT projects. On the other hand, Telegram is an instant messaging platform that can be used to send and receive messages, photos, videos, and other types of files.
The ESP32 is responsible for receiving the commands sent by Telegram through a BOT and processing them to control the relay that activates the water pump. The user can send commands to turn the pump on or off.
In short, water pump control via Telegram and ESP32 allows for efficient and easy management of water supply in real time, with the possibility of controlling the water pump from anywhere with Internet access.
