In this video, I'm making a carbon monoxide monitor for my home using an MQ7 carbon monoxide sensor, a DHT11 temperature and humidity sensor, and a NodeMCU microcontroller board. This sensor is ...

A temperature-controlled fan system that automatically adjusts the fan speed based on the environment using Arduino and DHT11 sensor. The system also displays the current temperature and humidity on a ...

Abstract: This paper reports a novel composite high-frequency vision-based tactile sensor with an embedded transparent MEMS-based piezoelectric module. Taking advantage of the transparency of the ...

Abstract: This project aims to design an IoT home automation application. The suggested system involves a range of sensors gathering temperature and humidity information, then using an Arduino ...

The ESP32 creates a Wi-Fi hotspot (SoftAP). When a device connects and opens the ESP32 IP address in a browser, a web page displays live sensor readings collected from the connected sensors.

Tired of condensation wrecking your shed tools or greenhouse gear? I built a no-frills ESP32 + DHT22 node that wakes every 15 minutes, grabs temp/humidity data, beams it over Wi-Fi, and sleeps—running ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...
