Analog TDS Sensor Water Conductivity Sensor Tester Liquid Detection Water Quality Monitoring

Note TDS probes cannot be used in water above 55 C The TDS probe should not be placed too close to the edge of the container as it will affect the display The head and lead of the TDS probe are waterproof and can be immersed in water but the connection interface and the signal adapter board are not waterproof Please pay attention to use Product Features 1 Wide voltage operation 3 3 5 5V2 0 2 3V analog signal output compatible with 5V 3 3V two control systems3 The excitation source is an AC signal effectively preventing probe polarization4 Waterproof probe for long term immersion in water5 compatible easy to connect plug and play no soldering requiredTechnical specifications Signal adapter board Input voltage 3 3 5 5VOutput signal 0 2 3VWorking current 3 6mATDS measurement range 0 1000ppmTDS measurement accuracy 10 F S 25C Size 42 32mmModule interface XH2 54 3PElectrode interface XH2 54 2P TDS probe Number of probes 2Overall length 83cmConnection interface XH2 54 2Pcolor WhiteOther Waterproof probePackage includes 1 x TDS signal adapter board1 x Waterproof TDS probe1 x Analog sensor linesource code define TdsSensorPin A1 define kValue 1 8 kValue value of calibrator TDS measurement to get TDS define VREF 5 0 analog reference voltage Volt of the ADC define SCOUNT 30 sum of sample pointInt analogBuffer SCOUNT store the analog value in the array read from ADCInt analogBufferTemp SCOUNT Int analogBufferIndex 0 copyIndex
