Wireless Dry Contact Sensors & Interface Meters
Wireless Dry Contact Sensors & Interface Meters
IOT Plus Wireless Dry Contact Sensors, Resistive Bridge Meters, and Interface Sensors capture critical insights from a wide range of systems, including equipment power status, strain gauges, inclinometers, door access points, voltage signals, turnstiles, machinery, factory automation systems, production lines, and mechanical barriers. You define the operating thresholds, and if any condition is breached, authorized personnel receive instant alerts via email, text message, or phone call.
Wi-Fi and Power over Ethernet (PoE) Dry Contact Sensor options are also available to support diverse installation environments.
How These Sensors Improve Operations
IOT Plus interface sensors integrate seamlessly with buttons, switches, relays, counters, and industrial or scientific equipment, enabling the collection of data such as voltage levels, actuation counts, revolutions, and open/close events. This data provides a clear picture of equipment performance, system reliability, and facility utilization, supporting smarter maintenance and operational decisions.
Designed for rapid deployment, IOT Plus Interface Sensors can be installed and configured in as little as 15 minutes.
Explore the IOT Plus Interface Sensor lineup, including Resistive Bridge Meters and Dry Contact Sensors, to streamline processes, maintain equipment health, and gain deeper operational visibility across your facility.

Frequently Deployed Together

Open/Close
Our wireless open/closed sensors provide information on the status of doors, windows, cabinets, etc. Know if a building or area is being accessed when it should not be, or if a door or window has been left open.

Motion Detection
Our wireless motion sensors use an infrared sensing technology to accurately detect movements made by people/animals within 16.4 ft (5 m) range.

CO2 Gas
The mems based wireless carbon dioxide sensor allows you to monitor the level of carbon dioxide (CO2) gas in the surrounding air. Monnit wireless CO2 sensors have a small footprint and low cost
