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 ...

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 ...

Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...

Holley EFI’s Terminator X Bluetooth Module enables full wireless tuning and real-time engine monitoring for Terminator X and ...

Most modern cars have tire pressure monitoring systems (TPMS), which will alert you if your tires need air. While most of the readings they give are accurate, they can still fail like any other part ...

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 ...

Abstract: Reliable real-time monitoring of lithium-ion battery (LIB) status is critical for ensuring both safety and performance, particularly in densely packed module designs. However, conventional ...

Abstract: Press-pack power modules are valued for their reliability and stability, making them indispensable to ensure safe operation of power electronics within smart grids. However, the complex ...

New L1+L5 SE873K5-D and SE869eK5-DRK modules extend Telit Cinterion’s GNSS roadmap from ultra-compact designs to ultra-precise, uninterrupted positioning Introduces a scalable next-generation GNSS ...

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 ...
