Turbidity Sensor With Amplifier Module Kit

The turbidity sensor with amplifier module converts the current signal output by the sensor into a voltage signal and performs AD conversion data processing through the single-chip microcomputer. The remodelling module has analogue and digital output interfaces. The analogue quantity can be sampled and processed by the single-chip A/D converter to know the current water pollution. The digital value can be adjusted through the potentiometer on the module to adjust the trigger threshold. When the turbidity reaches the set threshold, the D1 indicator will be lit, the output of the sensor module changes from high level to low level, and the single-chip monitors the change in level To determine whether the turbidity of the water exceeds the standard, so as to warn or link other equipment. The module is inexpensive, easy to use, and has a high measurement accuracy

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:

• VCC: Positive supply voltage, 5V cannot be used 3.3V
• AO: analogue signal output, output voltage range 0~5V
• DO: digital signal output is less than the set value and outputs high level; greater than the set value and outputs low level
• GND: negative supply voltage

Package Includes:

• 1 x Turbidity Sensor With Amplifier Module Kit
