Many businesses continue to accelerate because of adopting IoT (Internet of Things). IoT is essentially a term used to describe objects that are connected to the Internet. To maintain your competitive advantage, it is time that you learn more about it.
Since IoT involves a network of devices like smartphones, wearable, and other devices, you should know about iot sensors. Here’s what you need to know about sensors:
What is an IoT sensor?
You should understand that a sensor is a device that is able to perceive changes in a given environment. On its own, a sensor is useless but if it is incorporated in an electronic system, it can make a huge difference. Essentially, sensors can measure a specific phenomenon and transforms it into electric signals.
For it to be a sensor, it should meet three criteria. The first criterion is it should be sensitive to the environment that it will measure. The second criterion is it should not be sensitive to other things and the third criterion is it should not modify the measured phenomenon.
What are sensor properties?
There are many sensors that you can take advantage of. However, you should learn about the sensor properties at the onset. The properties include range, sensitivity, and resolution. Range refers to the minimum and maximum values of the physical phenomenon that the sensor can gauge.
Sensitivity, on the other hand, refers to the minimum change of the measured parameter, which can cause a detectable change of the gauged parameter and resolution is the minimum change that the sensor can detect.
What are the classifications of IoT sensors?
You should also know the classification of sensors. In general, it can be grouped as passive (sensors that do not need an external power source to monitor) or active (sensors that require a source to work), the method used and analog (sensors that generate continuous signals) or digital (sensors that produce discrete signals).
What are the common examples of IoT sensors?
The following sensors are extensively used in the IoT world:
- Temperature sensors: in the past, temperature sensors are mostly integrated into A/C control, refrigerator and similar devices. These days, it can be found in manufacturing, health and agriculture industry.
- Proximity sensors: refers to sensors that can detect the absence or presence of the closest object.
- Smoke sensor: as the name suggests, this device will sense smoke and its level.
- IR sensors: infrared sensors can measure the heat being emitted by particular objects.
- Motion detector sensors: as the name suggests, this sensor can detect the physical movement in a particular area.
- Accelerator sensors: this refers to a transducer, which can be utilised to gauge the acceleration experienced by a certain object because of the inertial forces.
It is clear that IoT has become popular and the current trend shows that it is the future. IoT helps with automation of different processes making the systems useful for businesses and regular costumers. Ultimately, IoT will help your company reach its goals faster while providing the best customer service.
