IR Telegram Alert
Smart Home · Board: ESP32 · Day 27 of 100
When the IR sensor trips, the ESP32 pings your phone via Telegram. Instant notifications from a five-dollar board.
How it works
When the IR sensor detects an object, the ESP32 opens an HTTPS connection to the Telegram Bot API and posts a message to your chat. Seconds later your phone buzzes with the alert. A five-dollar board becomes a notifier with global reach.
