Simple Temperature Monitoring with DHT22 & Arduino.

My project helps visually challenged people to walk without crashing into walls and obstacles. This help them to live freely without taking

A simple tutorial on getting readings from an ultrasonic sensor

Easy to build temperature and humidity sensor with a cheap 2x16 LCD.

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

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

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

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

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

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