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**.

## Datasheet

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**](https://ask.simplehw.eu/api-6/overview-for-beginners/), our universal firmware.

{% hint style="warning" %}
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.**

{% hint style="info" %}
Different liquids have different **electrical conductivity**, measured in **Siemens per meter or S/m** in the SI system.
{% endhint %}

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.
