Low-Power Wireless Concrete Curing Sensor


Wireless Concrete Curing Sensor


We designed a family of products for wirelessly monitoring concrete curing and building structural integrity. These sensors were low-cost units intended to be permanently interred within the poured concrete. They could operate off internal battery power for several years initially providing hourly temperature and humidity data during the curing phase and then automatically switching to a structural monitoring mode to provide very precise tilt movement measurements.
The data was collected locally by a Gateway which transferred it to an off-site database where it could then be accessed by users via a web portal. The sensors had a signal range of up to two kilometres. A compatible wireless repeater was also designed that could extend their range effectively indefinitely.
We also designed a low-power wireless calibrated vibration sensor that could interface to the same gateways and could be used on building and mining sites to ensure that safety limits were not being exceeded.
