PIC16F18345 Internet of Things (IoT)

Sensor Badge Demonstration

Summary

The number of connected applications is growing rapidly,

along with the need to handle multiple functions and

reduce power consumption. There are many communication

protocols used with different characteristics such as

wired, wireless, low energy and long-range connectivity.

Connected applications range from reading remote sensors

and sending the data to the cloud, to enabling remote

bootloader capability for functionality and software updates.

Offering an array of Core Independent Peripherals

(CIPs), Microchip’s 8-bit PIC®microcontrollers provide

the capabilities to handle multiple functions without the

core for low power consumption. The integrated analog,

digital and communication peripherals perform functions

autonomously, with the ability to alter system performance

based on feedback or other application needs. The multiple

on-board communication peripherals can be used with

external modules to enable Ethernet, Wi-Fi®, Bluetooth®

and long-range communications such as LoRa®.

The 20-pin PIC16F18345-based IoT Sensor Badge shows

this concept by interfacing with multiple sensors, sound

buzzer, communication module and RGB LEDs to perform

various application functions, including communication with

a smartphone application via a Bluetooth LE module.

Demonstration Highlights

The PIC16F18345 manages:

Four Modes of Operation

RGB LEDs

• The RGB LEDs light up based on the accelerometer

data. The LEDs on the axis with the most measure

force will light up. The center LEDs turns off when

the badge is tilted beyond 45 degrees.

• The RGB LEDs will light up based on a

predetermined pattern with color dimming

LEDs and buzzer

• The buzzer and LEDs are driven based on the

magnitude of the force sensed by the accelerometer.

The higher the force, the higher the pitch sound and

the brighter the LEDs.
