Dry contact
sensors

Get immediate alerts about the status of essential equipment

A simple sensor for monitoring and controlling a range of systems

Our wireless dry contact sensor monitors the status of any equipment that has a volt-free, dry contact output, such as lighting and HVAC in smart buildings, UPS status, security systems, fire alarms or machinery in manufacturing.

Their versatile application ensures efficiency, safety, and seamless integration into a building automation system.

Make contact monitoring sensors a building block of your IoT platform.

Dry contact sensors data for increased operational excellence

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 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.

Access real-time data locally or in the cloud

Data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi through an MQTT broker or ready connections to AWS and Microsoft Azure. No subscriptions or recurring fees.
