MerryIoT Open/Close
  • Compliance to LoRaWAN1.0.3

  • Hall-Effect sensor with a detection range of 1 cm

  • IP40 equivalent

  • Built-in 3-axis Accelerometer to detect any shock, vibration of an abnormal movement

  • Estimate battery lifetime: 3 years(Note: Battery life is mainly determined by the reporting frequency. Other factors include moisture and high temperature.)

  • Built-in alarm buzzer with sound pressure level 80 dB(min)

  • Power on-and-play installation

  • Support coverage test by pressing the test button

The MerryIoT Open/Close fits into any interior design and is easy to install. It is composed of two parts. The main body contains the active electronics to measure magnetic fields and transmit data, if any changes, to a LoRaWAN network. The other part is a permanent magnet of sufficient field strength to be detected by the Hall-Effect sensor on the main body. Built-in 3-axis Accelerometer, allows detection of abnormal movement from the window or door, enhance security measures.
