Batteries and Accumulators Demystified

A battery is a device which stores chemical energy and which can convert it into electricity. There are two types of batteries: primary batteries (single use) and secondary batteries (rechargeable), also known as accumulators.
In this post, I will explain how to chose the right batteries for your projects and how to compute how long will that battery last.
HB100 Microwave Motion Sensor Projects
I’ve recently discovered this video posted by Piotrfirst, who shows the output signal obtained using an amplifier circuit designed by following the guidelines from the application note of the microwave sensor.
If you’re interested to build a project like that, you can get a microwave motion sensor from here.
