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:
■ Badge tilt angle and temperature
■ Color mix and pattern for RGB LEDs
■ Buzzer drive and tone control
■ Bluetooth LE module
■ Remote control via smartphone/tablet application
Four Modes of Operation
■ Mode 1: PIC16F18345 with 3-axis accelerometer and
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.
■ Mode 2: PIC16F18345 with RGB LEDs
• The RGB LEDs will light up based on a
predetermined pattern with color dimming
■ Mode 3: PIC16F18345 with 3-axis accelerometer, RGB
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.
■ Mode 4: PIC16F18345 with 3-axis accelerometer, RGB
LEDs and buzzer
• Check board status with Android™ app via
Bluetooth LE
Smartphone/Tablet Application
■ View real-time tilt angle and temperature of the badge
■ View real-time status of each RGB LED
■ Change operation mode of the badge
■ Check battery voltage
