Sense The Surroundings

Build your own stand-alone temperature and humidity display with this guide on Instructables. The temperature at any one office varies quite a bit depending on the time of day, season. Although you can get custom made thermometers in less than 5$, however the user decide to build his own even if it cost a way too much then normal sensors. The placement of device was layout on the Prema-Proto Board. The author used a completely open-source electronics design application named Fritzing. It’s compatible with Windows, OSx as well as Linux. Its libraries can easily be found on the internet


The microcontroller used in this project is typically sold as a blank chip, but some vendors sell Atmel ATMega328P AVRs pre-programmed with the bootloader necessary to interface with the Arduino IDE. If you’re using a blank microcontroller, you’ll need to burn a bootloader to it with some kind of programmer. For the project you require a basic, DHT22 temperature-humidity sensor, a Prema-proto board , some caps, resistors, as well as multiplexed seven segment display along with an Arduino
