PIR Motion Sensor

Passive infrared (PIR) sensors are motion-detecting devices used in security systems across the world, even though you may not see them, they probably see you.

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.

Pololu Adjustable Boost Regulator 2.5-9.5V

This powerful, adjustable boost regulator can generate an output voltage as high as 9.5 V from an input voltage as low as 1.5 V, all in a compact, 0.42″ x 0.88″ x 0.23″ package. A trimmer potentiometer lets you set the boost regulator’s output voltage to a value between 2.5 and 9.5 V.

Lithium Ion Battery – 2.5Ah

These are very slim, extremely light weight batteries based on Lithium Ion chemistry. Each cell outputs a nominal 3.7V at 2500mAh. Comes terminated with a standard 2-pin JST-PH connector – 2mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger.

EMF Meter

EMF measurements are measurements of ambient electromagnetic fields that are performed using particular sensors or probes, such as EMF meters. These probes can be generally considered as antennas although with different characteristics. In fact probes should not perturb the electromagnetic field and must prevent coupling and reflection as much as possible in order to obtain precise results.

EMF probes may respond to fields only on one axis. Amplified, active, probes can improve measurement precision and sensitivity but their active components may limit their speed of response.

ADXL335 Triple Axis Accelerometer

Breakout board for the 3 axis ADXL335 from Analog Devices. This is the latest in a long, proven line of analog sensors – the holy grail of accelerometers. The ADXL335 is a triple axis MEMS accelerometer with extremely low noise and power consumption – only 320uA! The sensor has a full sensing range of +/-3g.

Global Positioning System

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.

The GPS does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information. The GPS provides critical positioning capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver.

Adafruit DS3231 Precision RTC FeatherWing

A Feather board without ambition is a Feather board without FeatherWings! This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator to any Feather main board. This RTC is the most precise you can get in a small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw.

With a CR1220 12mm lithium battery plugged into the top of the FeatherWing, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time.

Momentary Pushbutton Switch

This is a standard 12mm square momentary button. What we really like is the large button head and good tactile feel (it ‘clicks’ really well). This button is great for user input on a PCB or a good, big reset button on a breadboard. Breadboard friendly!

Adafruit HUZZAH32 ESP32 Feather Board

The HUZZAH32 is our ESP32-based Feather, made with the official WROOM32 module. We packed everything you love about Feathers: built in USB-to-Serial converter, automatic bootloader reset, Lithium Ion/Polymer charger, and just about all of the GPIOs brought out so you can use it with any of our Feather Wings.

That module nestled in at the end of this Feather contains a dual-core ESP32 chip, 4 MB of SPI Flash, tuned antenna, and all the passives you need to take advantage of this powerful new processor. The ESP32 has both WiFi and Bluetooth Classic/LE support. That means it’s perfect for just about any wireless or Internet-connected project.

Adafruit SHARP Memory Display Breakout – 1.3″ 168×144 Monochrome

The 1.3″ 168×144 SHARP Memory LCD display is a cross between an eInk (e-paper) display and an LCD. It has the ultra-low power usage of eInk and the fast-refresh rates of an LCD. This model has a gray background, and pixels show up as black-on-gray for a nice e-reader type display. It does not have a backlight, but it is daylight readable. For dark/night reading you may need to illuminate the LCD area with external LEDs.
