This tutorial will show you how to use DHT11 with Arduino.

Simple Temperature Monitoring with DHT22 & Arduino.

In this project I show how to build a particles detector with data display, data backup on SD card and IoT with Android application.

A simple tutorial on getting readings from an ultrasonic sensor

Read the soil moisture level (Dry-Perfect-Wet) and display results on a corresponding LED.

It reads from up to eight temperature sensors (DS18B20) and displays on the LCD display (16x2)

The purpose of "kukO2“ is to detect the CO2 content in indoor areas.

Give this the parameters you want and the LEDs will light up according to the temperature cold blue, green fine, red hot

The VCNL4000 is a proximity sensor with an integrated ambient light sensor.
