Build an Arduino heart rate monitor with a MAX30102 sensor and a 16x2 LCD.

Create a burglar-tripwire with the ultrasonic sensor.

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

Intelligently reduce the moisture in your basement/crawlspace to help control mildew growth and lower your heating/cooling bill.

Periodically measure environmental conditions and send them to WolkAbout IoT Platform to monitor the environment remotely.

As the title says, this is a pretty simple PIR motion controlled relay using an Arduino Nano.

The ElectronicsLovers Tech Team built this module, which has one difference from a usual one: it’s digital.

During the summers, many people get sunstroke because of playing in the sun for too long. So this device will prevent getting sunstroke.

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.

Water quality, anywhere, anytime!

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!

Generates maps based on distance between itself and obstacles autonomously and provides visual feedback.

Someone has been eating my cookies! Thankfully Arduino is here to help find out who it is.

It is a device that measures CO2 levels, inside and outside temperatures, and humidity.

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

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

Read temperature and humidity values in a remote location and store the data in an SD card.

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

Uses an accelerometer to level a platform.

Tracks compass heading, altitude, temperature, pressure, humidity, time, travel distance and GPS location during a hike.

A project that speaks on behalf of mother nature. It is real time air quality monitoring device.

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

Here we use PIR sensor and Arduino to detect the motion of a hand. This detection can be used to operate electronic equipment.

This project is about control of temperature in values of 23 and 25 grades and control for hysteresis using DHT22 and Arduino 101.
