Bluetooth sensors

Thanks to the Bluetooth module inside the device, there are many ways to expand the Smartbox 2 MAX with additional functions – using external sensors with Bluetooth support. You will install the accessories in vehicles, containers, or monitored objects and use external accessories to communicate with your SmartBox2 application, therefore you do not have to have an application for each sensor separately.
Note: Bluetooth sensors are available only for Smartbox 2 Max.

Supported devices

Smoke detector ES61

When the smoke concentration in the air reaches the set limit, the smoke detector emits an alarm with a high decibel immediately. IF you connect the detector via Bluetooth module with the app, an alert via a text message or a phone call will be sent to your mobile device.

  • alarm sound level: 85 db
  • sensitivity: 1% ~ 3 FT (0.14 – 0.43 dB / m)
  • ultra-low power consumption (3 years in standby mode)
  • innovative smoke chamber design with much higher sensitivity
  • size: 130 mm x 35 mm
  • options: 868 MHz / 915 MHz / Z-WAVE

CTek CTX battery monitor

The wireless car battery status monitor is from the Ctek company and is intended for connecting to a car (boat, RV,…) battery. It monitors the status of the battery. After detecting (in the application) a low battery level, you can connect the charger to the CTek connector and charge the battery immediately.

  • wireless communication via Bluetooth
  • charging the car battery through the CTek connector
  • designed for lead-acid starter batteries from 4.5 Ah (WET, MF, CA / CA, AGM and GEL)
  • Bluetooth 4.0 compatible

Water detector

Bluetooth sensor will alarm when a water leak is detected. Detection is done by measuring resistance between metal pins that are located on the base. The device can send data regarding the MAC address and low battery status reports.

  • operating temperature -20 ° C to 50 ° C
  • size 60 x 15 mm
  • sensitive detection
  • low-energy equipment, very long standby mode
  • low battery message
  • tamper detection
  • Bluetooth communication (100 m)
