The Triaxial Tilt Monitoring Sensor Node is an extremely precise and exceptionally stable three axis wireless tiltmeter. Variable reporting rates, a robust design and up to a 15 year battery life make this wireless tiltmeter suitable for many environments. The wireless tiltmeter nodes transmit precise readings from the site via one of our wireless communication networks (FlatMesh or GeoWAN) via a Gateway. You can visualise and interact with your data online using the WebMonitor platform.
