Submersible sensors rapidly detect bacterial pollution in water Fluorescence-based devices can alert authorities to contamination after a storm by looking for an improbable marker: tryptophan.

AutomationDirect’s ProSense line of level sensors now includes SLT series submersible level transmitters designed for applications such as lift station monitoring, construction by-pass pumping, tank ...

The Model AST 4530 Liquid Level Transmitter from American Sensor Technologies, Inc. (AST) is designed to measure the level of harsh liquids such as slurries, salt water and oil in vented tanks or ...

The S8000 Modular pH Sensor Platform is available as a submersion mounted sensor system, reducing measurement costs for open tanks and vessels as part of water and wastewater treatment applications.

Capacitive soil moisture sensors are very sensitive to salt content unless the frequency is high (> 50 MHz). This design appears to operate at 0.5 MHz.

The sensor I use changes it’s capacitance a lot between drizzle and heavy rain so that’s good. But I get a feeling the value is a bit unlinear to translate to rain volume.
