Wired vs Wireless

Wireless Sensors

Wireless sensors gather data about local conditions and share their findings with other components to further process the information. The major advantage that wireless sensors possess is they are very low maintenance and only require a small amount of power to be able to function. The other main attraction is that it is quick and straightforward to install. Oftentimes, it is the only option if hard wiring is difficult (which it can be in some older buildings) with construction limitations or in glass meeting rooms. It’s also easy to expand your monitoring area or add new sensors.

They are also able to support IoT applications for years before needing to be charged or have the batteries changed. Another positive of using wireless sensors is that it is likely that there is already wireless sensors in the area due to mobile phones, Wi-Fi etc. Wireless sensor technology works well to IoT applications allowing direct connection over Wi-Fi, 3G or 4G as well as local wireless networks. This makes it easy to take the opportunity to upgrade and add new technology when it becomes available

Depending on the type of wireless sensor you use there can be an extra cost with wireless sensor installation due to the extra components inside to help convert the analogue or digital signal to a wireless signal. Initial costs can be higher for wireless sensors but in the long run, can end up cheaper than wired.

Wired Sensors

Wired Sensors are known for their reliable systems as they link is directly from the sensor to the device receiving the input. As long as there is no damage to the wiring, then wired monitoring systems are less likely to fail than wireless sensors. This also means that it is more durable and will not need to be replaced very often but they do require a lot of space and can be more complicated to maintain. Additionally, they don’t interfere with any other wireless devices as they send low powered signals through cables. But data transmission can be affected by distance so they will perform better if they are near to the base.

Adding new sensors or expanding your monitoring area can cost and take time. This is because it requires reconfiguration and running of new wire to complete the set-up of the expansion.

Wired sensors can be vulnerable in the context of security systems as the wires can easily be cut and the system disabled.



Both wired and wireless have their pro’s and con’s which means you would have to assess which was better for you personally. Find out more about our WiVib Wireless Condition Monitoring
