Water Sensor (Grove 101020018) component
The water sensor uses a 1M ohm pull-up resistor. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace. You can use it with an analog input pin to detect the amount of water in contact between the grounded and sensor traces.

Properties |
|
VRef voltage |
| Used by the GetVoltage or GetString component macros to take an ADC reading and convert it into a Voltage. +VRef voltage x 10mV Default 500 = 5.0V | |
|
VRef option |
| Defines what is used as the ADC maximum reference. ADC Range = GND to VRef Voltage. VDD - Defines the microcontrollers power supply pin as the max reference, VREF+ Pin - Dedicated pin on the microcontroller to allow for a variable reference voltage. | |
|
|
Conversion speed |
| Clock setting to select how fast the ADC peripheral will perform an ADC conversion. The FRC setting is based on a RC time base and so will vary with temperature and pressure. Other settings are generally based on divisions of the master clock. | |
|
|
Aquisition cycles |
| Number of micro seconds to wait for the ACD input to charge before starting the analogue sample. | |
|
|
Bit Depth |
| Maximum number of digital bits the ADC can sample. 8 bit = ADC range 0 - 255 10 bit = ADC range 0 - 1023 12 bit = ADC range 0 - 4095 | |
|
Connections |
|
Channel |
| Analogue input channel - which pin is the analogue input conected to? | |
|
|
Simulations |
|
Tang Color |
| Colour of the moving part of the slider. | |
|
|
Marker Color |
| Colour of the marker line across the slider tang. | |
|
Scope Traces |
| Selects if the scope traces are automatically generated or not | |
