SW 07: Turbidity Sensor

Turn on the Turbidity sensor and read the turbidity value. The turbidity sensor can also read the temperature of the water.

Required Materials

1 x Waspmote 1 x Battery 1 x Turbidity Sensor

Notes

- The Turbidity sensor, is a digital sensor and must be used with the RS-485 module in combination with the Modbus library. The use of the Smart Water Board is no necessary with this sensor. - According to the sensor’s manufacturer specifications, the measurement of the turbidity must be done in a light tight pot, the sensor must be in a fixed position and the water container must be clean or the measure may be wrong.
