14.1. Introduction

Mopeka Pro Check-Water and Pro Check-Sensor LPG support has been added to Venus OS. These ultrasonic sensors use BLE (Bluetooth Low Energy), a wireless technology that allows devices to be networked within a range of about 10 meters, while consuming significantly less power compared to ordinary Bluetooth technology.

The Mopeka Pro sensors feature ultrasonic sensing for water and LPG tanks in horizontal or vertical cylinders and mount to the bottom of those tanks by magnets. The liquid level, temperature and sensor battery voltage is streamed wirelessly to the GX device.

Note that the Cerbo GX & Cerbo-S GX built-in Bluetooth connection is disabled when the internal CPU temperature exceeds 53 degrees C (influenced by load and/or ambient temperature). For reliable operation it is necessary to use a USB Bluetooth adapter.

USB Bluetooth adapters that have been tested and known to work:

  • Insignia (NS-PCY5BMA2)

  • Logilink BT0037

  • TP-Link UB400(UN)

  • Ewent EW1085R4

  • Laird BT820

  • Laird BT851

  • Kinivo BTD-400

  • Ideapro USB bluetooth adapter 4.0

A list of additional adapters that are also being tested, as well as adapters that have been tested and are known not to work, is available here:
