SEN0209 Gravity: Flexible Piezo Film Vibration Sensor
US$10.50
This is an Arduino compatible piezo film vibration sensor. It is made up of flexible piezo film and converter board. The sensor is able to detect vibration, flexibility, impact and touch. The film is a flexible component comprising a 28 µm thick piezoelectric PVDF polymer film with screen-printed Ag-ink electrodes, laminated to a 0.125 mm polyester substrate, and fitted with two crimped contacts. As the piezo film is displaced from the mechanical neutral axis and bending creates very high strain within the piezo polymer, high voltages (about ±90V) are generated. When the assembly is deflected by direct contact, the device acts as a flexible "switch", and the generated output is sufficient to trigger MOSFET or CMOS stages directly.

SEN0212 TCS34725 RGB Color Sensor For Arduino
US$14.75
After tens of millions of years of evolution, chameleons have formed a biological instinct where they can change the color of their skin to match their environment. This technique has enabled them to avoid detection from predators. We have taken inspiration from nature to develop the TCS34725 I2C Color Sensor. Using optical techniques, this sensor detects colors in its surrounding environment and provides a digital return of red, green, blue (RGB) values. This enables you to then recreate the detected colors using these values. The TCS34725 has a high sensitivity, wide dynamic range, and includes an IR blocking filter making it an ideal color sensing solution for use under varied lighting conditions. The sensor also includes four ultra-bright LEDs to allow the sensor to work without external light resources.

SEN0217 Gravity: Water Flow Sensor (1/2") For Arduino
US$17.50
The Gravity Water Flow sensor measures the rate of a liquid flowing through it. The YF-S201 water flow sensor consists of a plastic valve body, flow rotor and hall effect sensor. It is usually used at the inlet end to detect the amount of flow. When liquid flows through the sensor, a magnetic rotor will rotate and the rate of rotation will vary with the rate of flow. The hall effect sensor will then output a pulse width signal. Connect it to a microcontroller and you can monitor multiple devices such as your coffee maker, sprinkler or anything else, and control the water flow rate to suit your needs! The Gravity interface make it be compatible with Arduino IO Expansion Shield (DFR0265).
