Wireless Temperature Alarm

Project Name Suggestions Wi-Safe TempLink – Wireless Temperature Alarm Link. TempAlert ESP – ESP8266-based temperature alert system. TwinGuard – Transmitter & Receiver temperature guard system. AirLink Alarm – Wi-Fi temperature alarm link. HotLine ESP – Wireless hot temperature alert. I’d vote TwinGuard because it captures the idea of two linked devices working as a safety pair. Introduction Have you ever needed a remote way to know when your environment gets too hot? With a couple of ESP8266 boards, a temperature sensor, and a buzzer, we built TwinGuard , a wireless alarm system that alerts you when temperatures go beyond your set threshold — even from another room. How It Works Transmitter Reads the temperature using a DHT11 sensor. Displays the temperature on a built-in web interface. Sends a wireless alarm signal to the Receiver when the threshold is crossed. Hosts a captive portal in AP mode for quick configuration. Receiver Conn...

Creepy Noise Program Using The ESP32

fun prank project using the ESP32 — a creepy beeper that beeps at random intervals and enters deep sleep between beeps to save power and avoid suspicion. 🎯 Features of Your Creepy Noise Program: Produces a short beep using a buzzer. Beeps at random intervals between 1 and 15 minutes . After beeping, it goes into deep sleep . Wakes up after a random interval and repeats. 🧾 Wiring Assumptions: Buzzer connected to GPIO 13 (you can change this). Buzzer is active high (set HIGH to beep).   #include <esp_sleep.h> #define BUZZER_PIN 13  // Change as needed void setup() {   Serial.begin(115200);   // Initialize buzzer pin   pinMode(BUZZER_PIN, OUTPUT);   digitalWrite(BUZZER_PIN, LOW);   // Beep logic   beep();   // Pick a random time between 1 and 15 minutes (in seconds)   uint32_t minSeconds = 60;      // 1 minute   uint32_t maxSeconds = 900;     // 15 minutes   uin...
