EWS Switch Device


Global Coverage

The EWS Switch Device is a uniquely powerful datalogger and multi-communication transmitter for environmental, geotechnical and hydrological monitoring

This future proofs your assets from changing communication networks.

EWS Switch is the first smart multi communications transmitter in one compact unit, making remote monitoring easy and reliable, transmitting critical data over satellite or cellular networks. 

EWS Switch provides high quality data and performance at an affordable price. The effective, secure and continuous two-way data access across multiple communication networks allows for remote changes to the monitoring point without leaving the office.

The internal non-rechargeable battery provides extensive battery life and makes this option ideal for discreet deployments without the need for additional enclosures and extrernal power supply, i.e. inside road boxes, manholes, monuments or fixed directly to walls, posts or even trees.

Units come pre-programmed or use our App SwitchComm via Bluetooth for easy in field set up. With no laptop required for deployment, just swipe our mobile app to connect and securely transmit data instantly.

    Real-time Environmental Monitoring via the Iridium Satellite Network

    EWS Switch

    EWS Switch is the first smart multi communications transmitter in one compact unit. Switch between Satellite and Cellular easily and quickly.

    It can connect to any branded environmental sensor across a range of applications - eg any flow meter, pressure sensor, vibrating wire, water quality, pump sampler, flood warning equipment, radars, weather stations, tipping bucket rain gauges and more.

    Unlike it’s competitors, EWS Switch comes with a relay that can turn on pumps, lights and gensets - either via an alarm based schedule or manually. EWS Switch makes connecting to telemetry simple, ensuring your remote monitoring requirements are met and delivers the connectivity needed to ensure smooth long term data collection.
