“There are plenty of maker projects out there that show you how to connect a generic PIR motion sensor to a microcontroller. For those interested in learning about PIR motion sensors, then Adafruit’s How PIRs Work tutorial is worth …
Content for imp002
The imp002 breakout board contains a 3.3V TPS62172 step-down regulator (and the inductor/capacitors supporting it). This regulator allows for input voltages anywhere between 3.3V and 17V (voltages in the upper end of that range may produce some heat). This breakout can even support up to 500mA of continuous current. Like the Imp card, the imp002 module contains an embedded ARM Cortex-M3 microprocessor, an onboard WiFi module, and an antenna. Additionally, we have broken out 12 I/O pins from the imp002 module to standard 0.1" headers. Much like the Imp card, these pins can be used for a variety of functions.
