Description

Grove - Water Sensor detects the presence of water using exposed PCB traces. The sensor is made up of interlaced traces of Ground and Sensor signals. The sensor traces are weakly pulled up using 1 MΩ resistor. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the ground trace. This circuit will work with digital I/O pins of Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.


Application

  • Rainfall detection

  • Liquid leakage

  • Tank overflow detection


Features

  • Grove compatible interface

  • Low power consumption

  • High sensitivity

Please let me know whether the Water sensor input can be connected to my CC2530 SoC (Microcontroller) ADC pin. And also let me know how to interpret the voltage levels on the input pin. What is the maximum voltage level on the input?Do you have

The maximum voltage level of input is 5v. And we have posted the demo on the wiki for Arduino board. But i'm sorry this one can't detect the amount of water,it only can judge whether there has water or not. I'm sorry for the older confused information

The LiPo charger and 5V inverter are wired in parallel, so while there is power available the battery will be charged and the load will be supplied by the source. If the supply voltage drops too low, the battery will be discharged to provide the requir
