PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It’s also fully contained and very configurable. After you’ve provided power and ground, you can use the remaining 3 pins to configure whether the sensor is enabled (OEN), how sensitive the PIR should be to motion (SENS) and how long the output is active for (ON TIME). Even though there are 6 pins, the wires are flexible and long so the sensor is breadboard or perfboard friendly.
Low cost Lithium Polymer batteries have revolutionized electronics – they’re thin, they’re light, they can be regulated down to 3.3V and they’re easy to charge. On your phone, there’s a little image of a battery cell that tells you the percentage of charge – so you know when you absolutely need to plug it in and when you can stay untethered.
The Adafruit MAX17048 LiPoly / LiIon Fuel Gauge and Battery Monitor does the same thing. Connect it to your Lipoly or LiIon battery and it will let you know the voltage of the cell, it does the annoying math of decoding the non-linear voltage to get you a valid percentage as well!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
