Bluetooth has made life easier at both home and at work. It’s no surprise that the construction community has taken advantage of the technology and implemented it into many tools that we use on the job every day. However, sometimes it is beneficial to go the “old fashioned” route and skip the Bluetooth.
Maturity testing is one aspect of our field where it really does depend on YOU and your preferences on whether Bluetooth is right for you. Maturity testing addresses the guesswork and can prove if on-site concrete has achieved required strength and whether or not formwork removal and load application are feasible.
Bluetooth provides the ease of immediate connection between electronic devices such as mobile phones, computers, and wired sensors. However, Bluetooth does have some limitations. Bluetooth uses a 2.4GHz frequency to transmit data and frequently competes with other radio waves for transmitting information to its receiving device. Other devices that operate under a similar frequency include microwaves, wireless speakers, satellite dishes, monitors, cameras, cordless phones, power lines, and power stations. Water is an additional substance that can reduce the Bluetooth signal, so weather disturbances and even humans (with a significant volume of water in our bodies) standing between the transmitter and the receiver will slow down or inhibit the connection.
Wireless Bluetooth maturity systems are typically available as one of two options: with a transmitter that is completely embedded within the concrete, or with a transmitter that sits outside of poured concrete. Both options have benefits and limitations to consider before choosing a maturity system for your project.
Here are some of the pros and cons for both of the technologies.
