SST & Sparkfun collaborate on sensing hardware

LEDs on the Arduino can be easily programmed to indicate if the sensor is/isn’t immersed by the liquid (and thus determine if liquid level is too high/low). Using this hardware, hobbyists are provided with plenty of scope to experiment, while professional engineers have the opportunity to evaluate their prototype before moving on to a full scale design.

The Optomax devices have compact dimensions that allow them to be deployed within environments where there is only limited available space. As relatively long cabling can be supported, the sensor can be placed in close proximity to a liquid without any risk of the accompanying electronics on the Arduino being damaged.

Furthermore, as this solution is of an optical rather than a mechanical nature, issues such as the build-up of deposits, jamming, or wear and tear are avoided. A long term operational life span is thereby assured.

The liquid level switch can be supplied by SST in a robust housing with either a Polysulfone or Trogamid construction (depending on the particular application requirements). The complete solution has an operational temperature range that covers -25°C to +80°C.
