In this article we are going to take a look at DHTxx series sensors, which is used for measuring temperature and humidity, both the functionality is integrated into one module. We are going to see their specification, so that you can choose best sensor for your project and finally we are going to interface it […]
Newly Updated Circuit Projects:
Simple Digital Timer Circuit with 2 Digit Display
This simple digital timer circuit can be used to obtain timing output through selectable ranges, which can be set from 0 to 99 second, with 1 second interval, 0 to 990 seconds with 10 second interval, and 0 to 99 minutes with 1 minute interval. All these timing outputs can be visualized and tracked through […]
Password Lock Circuit Using IC 4017
