In recent years, the Internet of Things (IoT) has become a hot topic in many places around the globe. With the help of IoT sensor, an IoT device has the ability to collect data and communicate with other devices over the networks in real time, allowing efficient automation for a variety of purposes.
Due to the importance of sensors in IoT solution, not surprisingly it becomes one of fundamental elements aside from connectivity, data processing, and user interface. Learn more about sensors in the Internet of Things and enhance your insight.
What Is an IoT Sensor?
Sensors are where IoT workflow begins. They have been around for a while but IoT redefines a new generation—it helps increase the role of sensors itself. With IoT integration, the capability of sensors can be improved enormously.
Sensors can be defined as a device which detects and responds to different types of input from the surrounding. The input can be heat, motion, pressure, and other environmental phenomena. The device produces a signal output which is converted to readable display over a network.
According to the types of input, sensors can be divided into several types, among others, proximity sensors, temperature sensors, infrared sensors, and accelerometer sensors. For instance, temperature sensors can be used to maintain the right temperature and prevent overheat in multiple industries.
IoT Sensor Challenges
The increasing demand for IoT sensor comes with challenges. There are several factors that hinder IoT companies from using the sensor devices, including:
- Size
Size is currently one of the main challenges which limit the use of sensor devices. Finding a small sensor device is rather difficult nowadays because many of them are still bulky. For instance, GPS device which uses GPS tracker still has the size of a smartphone.
- Price
Many sensors are commonly high priced. This, however, also becomes one of the major challenges for the use of IoT sensor in devices. Finding a cheap sensor to reduce production cost is still difficult to realize in recent years.
- Battery Life
One of the most challenging factors to use IoT sensors is battery life. It is daunting to obtain a sensor device that offers long lasting battery life while still maintaining its small size. The reason is quite simple—size is closely related to the battery life. The bigger the battery, the longer its life.
IoT sensor unarguably plays a major role in the development of the Internet of Things. However, finding a sensor device that is small, cheap, and long lasting can be challenging. To get better in the future, the developer needs to work harder to address size, price, and battery life problem
