Overview
The sensor traces have a weak pull-up resistor of 1 MΩ.
The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace.
Believe it or not this circuit will work with the digital I/O pins of your Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.
Features:
- Grove compatible interface
- Low power consumption
- 2.0cm x 2.0cm Grove module
- High sensitivity
Application Ideas:
- Rainfall detecting
- Liquid leakage
- Tank overflow detector

… about the value of air quality, while simultaneously introducing them to some core STEM concepts, Arduino has you covered. The Arduino Greenhouse Kit and the Arduino Explore IoT Kit include experiments involving air quality, allowing users to build their own sensors and tracking tools to measure a range of data points like humidity, moisture, and the presence of particles like CO2. These projects both work using the Arduino MKR IoT Carrier Rev2, which has a VOC sensor. Use AI to monitor air quality [October 10, 2024 update] The Nicla family now includes the Arduino Nicla Sense Env, ready to provide real-time data on air quality – monitoring temperature and humidity and detecting TVOCs, NO2, O3, and other gasses – both indoors and outdoors, thanks to AI-ready Renesas sensors.
