It operates using real-time data from a humidity sensor, with a feedback loop ensuring that conditions remain within the desired range at all times. Fig. 1 shows a prototype built on a breadboard. The ...

Create a smart blind stick using Arduino to help visually impaired individuals navigate safely. This DIY project uses an ultrasonic sensor, buzzer, and LED indicators to detect obstacles and provide ...

Monitor temperature, humidity, and air pressure in every room with the Aqara Temperature Sensor. Optimize comfort, prevent damage, and automate your HomeKit smart home.

Xiaomi Mijia Smart Temperature and Humidity Sensor 3 Mini has launched for crowdfunding at $4, featuring a compact design, smart connectivity, and long battery life.

It’s a simple enough idea, and with an Arduino and a DHT11 temperature and humidity sensor, it was pretty easy to put together.

We’re going to be dealing with near-record heat and poor air quality in metro Atlanta on Wednesday.

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Our kit includes the Maker Uno RP2040 itself, four Grove to jumper cables, a USB-A to USB-C cable, a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a Grove cable, a SG90 ...

This is a BMP280/BME280 temperature/pressure/humidity sensor library for Arduino.

You can even build yourself something simple based on an Arduino Uno! The build uses Panasonic’s cheap “Grid-EYE” infrared array as the thermal sensor, in this case, a model with an 8×8 ...
