Key Design Elements for IoT Sensors

Sensors from the Internet of Things (IoT) are increasingly widespread in many industries. However, when decision-makers invest in those technologies, they want to be sure that the end products are well-designed and up to their standards. IoT solutions sensor designers are primarily responsible for producing sound, secure, and economical products. Here are some crucial considerations for anyone designing sensors or trying to choose the best devices to purchase.

Key design element

  1. Power sources

Many IoT solutions sensors feature built-in rechargeable batteries or are powered by wall plugs. For some applications involving networked sensors, those options are not practical.

Believe whether or not you want to use them to track birds in a challenging location for several years. In situations like that, it’s essential to create long-lasting power sources that needn’t frequently replaced or recharged to function. Without efforts to upgrade the current power sources, research predicts that by 2025 there will be 78 million abandoned IoT platform batteries.

One alternative is to build the sensors to use energy harvesting, where the environment around them powers the parts. Some systems have energy-storage components, allowing them to function at night or in overcast weather. Making them work with sunlight is one of the most straightforward solutions.

As an alternative, many people use sensors in areas with high vibration. They might make good mechanical energy-harvesting system candidates. For instance, the vibrations of some large machines can generate up to 150 microwatts of energy per centimeter square. It is simple to understand why a sensor powered by mechanical energy would work well in a machine monitoring application.

2. Hardware Size

The downsizing of Internet of Things (IoT) goods and the sensors inside them results from innovations like higher-density circuits and smaller total component sizes. Smaller IoT platform sensors aren’t always preferable to larger ones, though.

The hardware sizes required to make the sensors function effectively will be determined by factors like desired GPS performance and antenna size and kind. Consider examples like big home appliances with IoT solutions connectivity. No need to waste time developing a sensor for an innovative washing machine as small as possible. This is so because the sensor’s primary product is already quite big.

3. Ruggedness and durability

Another crucial design component for a successful product is understanding the circumstances IoT sensors must survive during typical operations. Ingress protection ratings for many waterproof objects are available to assist users in understanding how well they keep water out. For instance, an IP67-rated product can be submerged for 30 minutes in 1 meter of water without damage. A product’s level of dust protection is also described by its IP rating.

Severe conditions that pose risks to specific IoT platform sensors under development must be considered by the professionals entrusted with creating sensors. Some goods with sensors may be exposed to the environment almost constantly. In these situations, techniques to keep fragile parts enclosed will ensure they continue functioning even if users expose them to moisture or temperature extremes.

4. Security

IoT users and owners with sensor-equipped gadgets must take basic security measures to protect them from hackers. They might employ software that guarantees that only authorized users can access linked equipment, or they might set tough passwords.

Security, however, must be a top priority while developing sensors. A communication protocol that transfers passwords or other sensitive information in unencrypted forms could be a design error. Another severe omission would be allowing access to the control interface without authenticating.

Ensuring firmware updates may only occur when the new material originates from the device manufacturer or another reliable party is one way to create an IoT device with greater security.

5. IoT Sensors with Careful Design Produce Beneficial Products

Teams are more likely to produce high-performing products when they take the time to consider the complete process and these crucial components.

Mistakes can and do occur. Even things that have been carefully thought out can have some flaws. However, those knowledge gaps can be closed by holistically considering the sensor and its function. Additionally, it helps when IoT design teams view all blunders as teaching moments. To encourage a culture of continuous development, keep a record of those and be willing to improve.


IoT (Internet of Things) sensors are becoming more common in several businesses. Designers of IoT sensors are primarily responsible for creating practical, safe, and affordable devices. Here are some crucial aspects to assume when constructing sensors or selecting the best gadgets.
