TDS Sensor Module Dissolved Solids Analog Signal Soluble Solid Water Quality Detection Temperature

Output signal range: 0-2.3V Power supply voltage: 3.3- 5.0V TDS measurement range: 0-1000ppm Working current: 3-6mA TDS measurement accuracy: 5%F.S. (25) TDS probe interface: 2Pin XH-2.54 Temperature sensor interface: 3Pin XH-2.54 Signal output: 0-2.3V analog signal output, compatible with 5V and 3.3V control systems Excitation source is AC signal, effectively preventing probe polarization Waterproof: Waterproof probe can be immersed in water for long-term measurement TDS probe parameters: TDS probe is suitable for 2 points of PE pipe Pin The module is connected to TDS probe through 2PinXH-2.54 connector, and temperature sensor interface is extended to facilitate software temperature compensation design. VCC: supply voltage+ GND: supply voltage- T1: Temperature sensor signal output port (temperature compensation can be performed through software) AO: Analog signal output (output voltage range 0-2.3V) +:Temperature sensor power supply+ T: Temperature sensor signal line -: Temperature sensor power supply- 1: TDS probe lead 1 2: TDS probe lead 2 Colour:Blue Material:PCB Package Contents: 1x TDS sensor module Only above package content, other products are not included. Note: Light reflection and different displays may cause color of item in picture a little different from real thing. The measurement allowed error is +/- 1-3cm.
