Wireless Dry Contact Sensor

Description

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.

• Reports dry contact status changes in real time and status updates every 15 minutes
• Connect to the device using push wire connection of two wires
• Solar powered using ambient room light – optimally angled to absorb light – with a battery back up for periodic low light conditions. Batteries typically last up to 10 years
• Transmits data via EnOcean wireless protocol: up to 30 meters in buildings and 300 meters in free field

More Benefits:

• Dry Contact: The term “dry contact” refers to a circuit that doesn’t carry a voltage or current.Instead, it simply detects whether a connection (contact) exists between two points. 
• Wireless Transmission: These sensors communicate wirelessly, often using technologies like LoRaWAN or Wi-Fi, to transmit data to a gateway or monitoring system. 
• Applications: Dry contact sensors are versatile and can be used in various scenarios, such as:

  • Monitoring door or window openings 
  • Tracking equipment status (e.g., a machine’s power on/off) 
  • Detecting the activation of a button or switch 
  • Monitoring float switches in HVAC systems 
  • Detecting the status of a fire alarm or security system 
• Benefits: Wireless dry contact sensors offer several advantages:

  • Remote Monitoring: Allows for real-time monitoring of devices or events from a distance. 
  • Easy Installation: Wireless connectivity simplifies installation and avoids the need for extensive wiring. 
  • Flexibility: Can be used in a wide range of applications and environments. 
  • Integration: Easily integrated into existing systems or building automation platforms. 
• Principle of Operation: The sensor typically has two wired terminals. When a connection is made (or broken) between these terminals, the sensor detects the change and transmits a signal wirelessly
