The Triaxial Tilt Monitoring Sensor Node is an extremely high precision and exceptionally stable three axis wireless tilt monitoring sensor. Variable reporting rates, a robust design and up to a 15 year battery life means that Senceive tilt sensors are well suited for all environments. The wireless tilt monitor sensor nodes communicate reading through one of Senceive’s wireless communications networks (FlatMesh or GeoWAN) via a Gateway and on to our web-based platform called WebMonitor where you are able to monitor your results.
