Abstract: Temperature and humidity controlling system which has the function of alarm memory was designed by PROTEUS software. The MCU AT89C51 was used to control the whole system. The humidity and ...

Want instant SMS alerts from your ESP32 without relying on a bulky GSM module? Whether it's motion detection, a sudden temperature spike ... ESP32 communicate with the DHT11 through the sensor’s ...

Thermal excursions included those typical in mixed technology assembly processes. Exposure to temperature/humidity was varied from near ambient (35/spl deg/C/85% RH) to harsh (steam aging). A minimum ...

This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...
