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 ...

How Does the ESP32 WhatsApp Alert Message Work? The ESP32 uses its built-in WiFi to communicate with CircuitDigest Cloud WhatsApp API and send WhatsApp notifications whenever a sensor condition is ...

UNSW researchers have developed a thermal-aware tracking algorithm that reduces solar module temperatures and UV exposure during inverter clipping and curtailment, slowing degradation without lowering ...

The Ikea Timmerflotte temperature and humidity sensor is a complete steal for what it offers. It’s affordable, Matter-compatible and delivers reliable readings, all wrapped in a clean, unobtrusive ...

Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor module. Given the power of microcontrollers these days, it was only a matter ...

In this module, a waterproof temperature sensor is used to measure the temperature and relay the measured temperature data to a Raspberry Pi. A software application implemented using the Python3 ...

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...
