Water

Water sensors: TDS and pH sensors and meters, turbidity sensor, YF water flow sensors, float switches and water level modules for aquariums and hydroponics.

Sensors for aquariums, hydroponics, tanks and water quality projects: analog TDS sensor modules and TDS/EC meter pens, liquid pH sensor modules with electrode probe and pH test pens, a turbidity sensor kit, 0.5 inch and 1 inch YF Hall-effect flow sensors, the ZP4510 vertical float switch and a simple water level module. pH probes need calibrating with buffer solution (in Diagnostic/Testers), and the analog modules connect to an analog input.
