This water sensor module is part of the Twig system. This sensor works by
having a series of exposed traces connected to ground and interlaced between the
grounded traces are the sens traces. 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.

Applications Ideas
Compared with the previous version, The Shield Bot V1.1 can use the usb port
of PC to charge battery. And the charging efficiency is greatly improved after
we optimize the circuit. And you can use the Arduino/Seeeduino Vin pin to fast
charge.
Note: Compatible Arduino Board not included, try the Seeeduino.
TinkerKit Hall Sensor module creates a voltage related to the magnetic field around the sensor. This can be used to detect distance from a nearby magnet. Hall sensors can also be used to detect the magnetic field induced in a wire or coil.
TinkerKit Sensor Shield V.2 allows you to hook up the TinkerKit Sensors and Actuators directly to the Arduino without the use of the breadboard. It has 12 standard TinkerKit 3 pin connectors.
TinkerKit Tilt Sensor module can detect when it is at an angle. This module contains two contacts and a small metal ball. When the sensor is in its upright position, the ball bridges the two contacts, completing the circuit. When the board is tilted, the ball moves, and the circuit opens. When upright, the module outputs 5V and when it is tilted, it outputs 0V. When connected to an input on the Arduino using the TinkerKit Shield, you can expect to read a value of 1023 when in its upright position and 0 when it is titled.
This module is sensor. The connector is an output, which must be connected to one of the input connectors on the TinkerKit Shield.
The Goniometer can be used to measure the dynamic motion of a limb during different types of physical activity.
The Low-g Accelerometer is the best choice for most acceleration experiments, including Newton’s second law, simple harmonic motion, and the relationship between acceleration and force. It can also be used to study one-dimensional motion of a car (real and toy), an elevator, a pendulum bob, or an amusement park ride.
