As the name suggest, the Internet of Things (IoT) is all about connecting ‘things’ with the ‘internet’. Once connected, the ‘thing’ becomes an IoT device (commonly referred to as a ‘smart’ thing). An effective IoT device needs to have sensors, actuators and a Radio Frequency (RF) module that allows it to transmit and receive data / signals via the internet.
Smartphones are arguably the most versatile IoT devices. They are packed with sensors. And almost everybody has one! (81% of Americans own smartphones, up from 25% in 2011 – Pew Research center). Mobile applications running on smartphones can leverage the IoT data connectivity supported by their array of sensors to enable a variety of innovative use cases.
List of some Smart IoT Sensors
Most modern smartphones can directly capture and compile data from as many as 14 different sensors.
- Accelerometer: It informs about how fast you are moving in a linear direction.
- GPS: Global Positioning System sensors connect with satellite-based navigation systems to provide location, velocity, and timing data.
- Gyroscope: It is a three-axis sensor that determines the angle, pitch and roll in any device.
- Magnetometer: This sensor is used for measuring earth’s magnetism.
- Biometrics: For tracking and monitoring Fingerprint, Retina, Face & Voice, you have biometrics sensors.
- Camera: For image, video capture & display, you have cameras.
- Barometer: This sensor informs you about short term weather changes and is also used to estimate altitude.
- Proximity Sensors
- Bluetooth connectivity
- Barcode readers
- Touchscreen sensors
- Heart rate monitor
- ECG
- Haptic feedback sensors
Use cases where a smartphone can be used as an IoT device include Personal emergency response, fitness tracking, location based asset tracking and natural vision processing. Smartphones can be used as a Bluetooth gateway for wearable Bluetooth devices that enable many IoT monitoring apps. Identity verification, GPS based guidance, position/orientation awareness apps and games are well suited for smartphone based implementation.
When is a smartphone not a smart choice? Applications that require IoT devices to be placed in remote locations or have a long battery life are not suitable for smartphone use. Industrial monitoring/IIoT and healthcare applications that require wearable devices fall within this category. Cost is another limiting factor.
Smartphones are providing opportunities to offer new products and services that can change the way we live our lives and conduct business.
