Dry contact sensors

Get immediate alerts about the status of essential equipment

Our wireless dry contact sensor monitors 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.

Solar-powered with battery back-up for easy install

The sensors use ambient room light – natural or lighting – with a battery back-up, making them super easy to install and very low maintenance.
