Some days ago the educ8s team presented a weather station using the DTH11 humidity sensor and the BMP180 barometric pressure and temperature sensor. Although the BMP180 worked well, the DTH11 was not so accurate.
This new design uses the DHT22 humidity sensor, a more expensive but more accurate selection. The NOKIA 5110 display is used to output the results. Sleek!.
This step-by-step video will guide you through the design. Read the description of the video for the code and the data sheets. Well done!
