Turbidity sensor can detect the turbidity(clearness/murkiness) of water.

### Product Specifications

* Voltage:3V\~5V
* Port: 3pin
* Operating Temperature: 5°C\~85°C
* Weight: 30g

### Hardware Connection

Connect Pin A to a signal pin, G and V to GND and 3V.

```
Turbidity Sensor is a analog sensor, it needs to connect to an analog pin.
It is recommended to use turbidity sensor with a water temperature sensor.

#### Turbidity Sensor Programming

```
Calibrating the turbidity sensor with the water temperature can result in higher accuracy.
Note: The sensor is not waterproof, please do not submerge in water.
