Wireless dry contact sensors

Get real-time alerts about the status of essential equipment

Our wireless dry contact sensors monitor the status of any equipment that has a volt-free, dry contact output, such as UPS status, security systems, fire alarms or air conditioning units. The small, energy harvesting devices use ultra-low power wireless and battery-less technology, making them easy to install and very low maintenance.

Get accurate, reliable status updates

The sensor simply connects using a push-wire and sends instant open/close updates if the contact status changes.

Solar-powered or battery-powered for easy install

The sensors use ambient room light – natural or lighting – for power, or long-life batteries, making them super easy to install and very low maintenance.
