The SHT 8815 is a robust active water sensor with two V4A stainless steel contacts and a potted plastic housing made of Wepuran®.
As soon as water or another conductive liquid touches the contacts, the resistance between the two wires drops from several megaohms to several hundred ohms.
➡️ This allows the sensor to be easily connected to digital inputs with an internal pull-up or pull-down resistor .
The SHT 8800 is not suitable for direct connection to Schabus water detectors . Please note this during integration.
Digital inputs from home automation and building management systems
Controllers with internal pull-up or pull-down
Active water sensors like the SHT 8815 require auxiliary power (e.g., the control unit's operating voltage). They respond to water contact with measurable electrical changes – in this case:
➡️ Resistance reduction that can be reliably detected at digital inputs.
Since electrolysis occurs with DC voltage in humid environments, the sensor is designed for regularly dry environments and only occasional water sources .
The sensor cables (3 x 0.14 mm²) are flexible and can be easily extended (max. 20 meters).
LIYY cables are temporarily waterproof, flame-retardant, low-adhesion, self-extinguishing, and resistant to oils, greases, coolants, and lubricants.
