Its design is based on the WSP2110 whose conductivity changes with the concentration of VOC gas in air. Through the circuit, the conductivity can be converted to output signal that corresponding to the gas concentration. This sensor can detect the gas whose concentration is up to 1 ppm. It’s suitable for detecting formaldehyde, benzene, toluene and other volatile components. This product can be used to detect harmful gas in the home environment.
The Grove-Tilt Switch is the equivalent of a button, and is used as a digital input.
Inside the tilt switch is a pair of balls that make contact with the pins when the case is upright. Tilt the case over and the balls don’t touch, thus not making a connection. It is wired to the SIG line, NC is not used on this Grove module.
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.
Stencil printing is the process of depositing solder paste on the printed wiring boards to establish electrical connections. It is immediately followed by the component placement stage. The equipment and materials used in this stage are a stencil, solder paste, and a printer.
