In this project, we built a Smart Egg Incubator using the MakerBuddy IoT Kit, a DHT11 temperature sensor, a relay module, and a 5V bulb. The purpose of the project is to demonstrate how temperature ...

About five years ago, I worked on IoT for my job. I once used this DHT11 (a blue temperature and humidity sensor) to build a ...

In this project, I connected a DHT11 temperature and humidity sensor to a NodeMCU ESP8266 and used KiwisIoT to monitor temperature and humidity readings online. The ESP8266 collects data from the ...

They might have worked for a while now but the important features only just landed ...

Build a DIY ESP32 LoRaWAN sensor node to track garden temperature and humidity from up to 600 meters away. Includes PCB ...

Build a tiny ESP32 OLED keychain with a 1.3-inch display and custom 3D-printed enclosure. Wire the ESP32 S3 and program it via Arduino.

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Continuous glucose monitors have become popular among people who have diabetes and those who need to track their glucose levels. These devices are painless and can easily sync up to an app on your ...

There are plenty of “robot” projects out there that are really just a small remote control platform of some sort. We often like to think of robots of having some sort of autonomy though. [Luca Fagioli ...

Air sensor monitors that are lower in cost, portable and generally easier to operate than regulatory-grade monitors are widely used in the United States to understand air quality conditions. This ...

EPA has established air sensor loan programs independently and through collaborations with libraries, tribes, museums, and others to enable the public to learn about air quality in their communities.

Earlier this month, we saw how the humble ESP32-S3 could be turned into an SDR transmitter and receiver; then we saw ...
