Turbidity Sensor Module + Water Turbidity Sensor + CH340g USB to TTL Module

Turbidity Sensor Module + Water Turbidity Sensor + CH340g USB to TTL Module

Description:
The turbidity sensor uses optical principle to comprehensively judge the turbidity situation through the light transmittance and scattering rate in the liquid solution.

Because the turbidity value is a gradual change, it is usually detected in a dynamic environment.

The turbidity value collected by the sensor requires external control for AD conversion and conversion to obtain the turbidity situation in the corresponding environment. Therefore, the sensor also needs to make peripheral circuits to detect in the system.

Note:
- Please contact us for schematic diagram + AT instruction set + serial assistant software + user manual after purchasing. Thank you!
- The turbidity detection module measures particulate matter in water, so a turbidity calibration solution is required for calibration, instead of using a multimeter to directly measure voltage. The output voltage of each module is different. Please avoid exposure to light while using this module. Light, temperature and voltage will make the voltage of the module different. 0-4.5V is only a reference voltage.
- Each sensor has a certain error, so it needs to be calibrated in actual use.
- Do not immerse the sensor completely in water. Just soak the end with the small round head with a split into the water.
- The voltage must not exceed 5V.
- Do not use this product in a humid place, otherwise it may cause damage.

Applications:
- It can be used to measure the degree of water pollution in washing machines, dishwashers, fish tanks and other products. The degree of cleanliness of the solution is determined by measuring the degree of water fouling, and the appropriate time for changing the water is determined to reduce the energy consumption and save water.
- It can be used for river and sewage measurement, clarification tank detection and water quality research, etc.
- The sensor can also be used in electronic design, graduation design, electronic competition experiments and other occasions.

Package Included:
- 1 x Turbidity Sensor Module
- 1 x Water Turbidity Sensor
- 1 x CH340g USB to TTL Module
