SimpleLeak 3.0 Introduction


The SimpleLeak 3.0 is a universal Sigfox-based leak detector with a loud buzzer and the possibility to measure temperature as well. It's designed so it fits almost anywhere and the included battery can last for many years.


You can find more technical information and also all available device versions in a datasheet we have prepared for device presentation.

API 6 firmware

The SimpleLeak 3.0 uses the API 6, our universal firmware.

Please note that the SimpleLeak currently supports only one mode - Leak detector (0x0A). Changing the mode is not recommended as the device will not be able to switch back to Leak detector! Please use the downlink only for the fine-tuning settings of the Leak detector mode.

Can the sensor recognize presence of other liquids than water?

Yes, but there are limits.

Different liquids have different electrical conductivity, measured in Siemens per meter or S/m in the SI system.

The sensor is calibrated to detect water first and foremost, and liquids like gasoline or diesel have much lower conductivity by several orders of magnitude (gasoline 25 pS/m, diesel 5pS/m, compared to deionized water at 5.5 μS/m or typical drinking water at 5–50 mS/m), which means a different sensor has to be used (such as a leak-rope).

The output range is dependent on battery voltage, but in controlled lab environment, the lowest liquid conductivity detectable by the SimpleLeak is around 0.1 μS/m. This is around the worst case value, but please note other factors such as temperature play a role as well.
