Gravity: Analog Electrical Conductivity Sensor PRO (K=1) Shipping:1 day It uses a PIC12C508 to

It uses a PIC12C508 to perform the control functions and standard 40khz piezo transducers

so we generally recommend using pulsed signals with them

Each LED and button can brought out to the side connectors

This is the tiniest little LED grid we could make

Gravity: Analog Electrical Conductivity Sensor PRO (K=1) Shipping:1 day It uses a PIC12C508 toConductivity is the reciprocal of an object's resistivity. It represents a material's ability to pass a current. In a liquid, conductivity is a measure of a solution's ability to conduct electricity and can reflect the amount of dissolved or salinity of a water source, so it's an important parameter in water quality monitoring. DFRobot Gravity: Analog Electrical Conductivity Sensor PRO(K=1) is specially used to measure the conductivity in aqueous
