This is an Arduino Uno with a DHT11 temp/humidity sensor with and LCD screen powered by a power bank.

Use HC-SR04 on Arduino with Processing

We built a stylish and useful humidity and temperature sensor for our home workshop that uses color to alert us to big swings in humidity.

Use the DHT Temperature Sensors in C# code via a C++ Windows Runtime Component to implement a one-wire protocol on Windows 10 and the RPI2.

This is tutorial to help you understand ultrasonic and buzzer and go deeper into learning Arduino, follow these steps and give me feedback.

The sunflower follows the light using a servo motor and two photoresistors.

Water quality, anywhere, anytime!

This is the first generation of my Arduino based mini-weather station with Wi-Fi connection, which is able to post data publicly online.

Short and easy, read distance 2 - 400 cm and plot it in I2C OLED screen.

The ESP system make it easy to recognize gestures you make using an accelerometer.

Track the sun in X and Y with this simple Arduino project.

I'm going to show you how to make an LCD thermometer with an Arduino UNO and a LM35/36 analog temperature sensor.

Very useful project made at school that detects some weather data.

It is a simple tutorial on how to create little a security device using an Arduino.

How to measuring the air quality of the Open Data Institute using an Arduino and a Shinyei PPD-42.

A fall detection system based on Arduino, Windows 10 and Microsoft Azure

A step-by-step tutorial for interfacing an IMU (Inertial Measurement Unit) sensor with an Arduino and reading the Yaw, Pitch & Roll values.

LIDAR stands for Light Detection and Ranging. LIDAR is used for many applications including 3D scanning, mapping, laser guidance, etc.

Anemometer or a wind speed measuring device is a common weather station instrument. It was costly online, so I built one!

I built an Arduino Weather Station. It uses a DHT 11 (it will also work with DHT21 DHT22).

Use an Arduino, two small servo motors with light sensing photo resistors to steer a solar panel towards the sun. UPDATED

Check the humidity & temperature of your terrarium with a DTH22 humidity and temperature sensor and display this on an LCD I2C 16x2 display.

This is the first version of my Arduino Weather Station, a very simple project that will give you weather information.

We connect a VL53L0X Laser time-of-flight sensor to an Arduino to measure the liquid level in a tank using ToF ranging.
