The composition of the turbidity sensor module is shown below. The module is connected to the turbidity sensor through the 3Pin XH-2.54 connector. Adjust the knob of 10K blue potentiometer to adjust the trigger threshold of digital output.
The module pin definitions are as follows:
1 VCC: Positive supply voltage, 5V cannot be used 3.3V
2 AO: analog signal output, output voltage range 0~5V
3 DO: digital signal output is less than the set value and outputs high level; greater than the set value and outputs low level
4 GND: negative supply voltage
Technical index:
Working voltage: 5.00V DC
Working current: 40mA (MAX)
Response time: Insulation resistance: 100M (Min)
output method:
Analog output: 0~4.5V;
Digital output: high/low level signal (the corresponding threshold can be selected by adjusting the potentiometer)
Operating temperature: -20℃~90℃
Module size: 38.6mm*22.1mm
