“Working with electronics has become much easier after the arduino line of boards, the large community develops a large number of libraries that make interfacing with any sensor with the arduino easy. And now years later, after the launch of the first arduino board there are thousands of arduino projects on it. Here is a project for those who like gardening and growing plants in a greenhouse, growing plants requires specific temperature and humidity to be maintained in this instructable I’m going to show you how to make a device that measures the humidity data and temperature data and logs it and displays it on a LCD screen. You could run more than one sensor at once. So in this instructable I’m going to show you How to make a temperature and humidity logger with the arduino and DTH11.”
