How Does it Work?

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

What we Can Do With it?

>Make a Weather Box

>Digital Thermometer

>Fire Alarm

>Know the weather outside

and lots more………….

>Plant Watering

Things Required

>Arduino Uno  (The brain)

>DHT11 Temperature and Humidity sensor  (http://goo.gl/qHFAU5) (http://goo.gl/qHGwLi)

>Jumper Wire (Male To Female)

Lets Get Started
