The DHT11 temperature and humidity sensor is a nice little module that provides digital temperature and humidity readings. It’s really easy to set up, and only requires one wire for the data signal. These sensors are frequently used in remote weather stations, soil monitors, and home environment control systems. The programming is simple too, and many libraries and example code in both Python and C already exist. In this tutorial, I’ll show you how to connect the DHT11 to the Raspberry Pi for output to an SSH terminal or to an LCD, then give you some example programs for programming it with either C or Python.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
