HaViMo-PS

HaViMo-PS™ is a vehicle presence measurement sensor. The product is used to substitute induction loops vehicle detectors. It provides a more robust, maintenance free and flexible solution with a full compatibility to a wide range of junction timing controllers. The device can be configured locally or remotely via HaViMo-Cockpit™. It can also be extended to report the statistics to HaViMo-Cloud™ server for later analysis and alarming.

Application

  • Smart City Management
    • Induction Loop Replacement 
    • Adaptive Junction Timing Control
    • Parking Lot Automation

Extensions

  • Optical
    • WIDE_EXT
      • Wide angle adapter: Increase the view angle of the camera with a factor of 2x. Useful for wide Highways or when the sensor can not be installed high enough.
    • TELE_EXT
      • Tele adapter: Zoom in with a factor of 2x. Useful for measuring far targets.
  •  Electrical
    • HAVIMO-2-LAN
      • HaViMo adapter to Ethernet: Allows TCP/UDP connection to the device. MODBUS-TCP connection is supported on this adapter. Can also be used for connecting to HaViMo-Cloud™ service if internet connection is available. 
    • HAVIMO-2-WLAN
      • HaViMo adapter to wireless LAN: Allows TCP/UDP connection to the device. MODBUS-TCP connection is supported on this adapter. Can also be used for connecting to HaViMo-Cloud™ service if internet connection is available. 
    • HAVIMO-2-RS485
      • Adds RS485 Physical Layer to HaViMo hardware. This allows differential data communication over long distances. Used for local configuration of the device.  
    • HaViMo-2-GPRS
      • Connects HaViMo devices to HaViMo-Cloud™ service over GPRS. A SIM card with enabled data plan is required by the adapter to function properly.
    • HaViMo-2-3G
      • Connects HaViMo devices to HaViMo-Cloud™ service over GPRS. A SIM card with enabled data plan is required by the adapter to function properly.
    • HaViMo-OUT
      • Adds 4 digital trigger outputs to the device. It can be used to connect the unit to the junction timing controller.
