This Disk Load Cell (sometimes called the Strain Gauge) can translate up to 200kg of Pressure(Force) into a Electrical Signal. Each Load Cell is capable of measuring the electrical resistance that changes in response and proportional to the voltage (eg pressure or force) applied to the disk. With this gauge, you'll be able to tell how heavy an object is, if an object's weight changes over time, or if you simply need to feel the presence of an object by measuring the tension or load applied to a surface.

Grove's capacitive humidity sensor (corrosion resistant) is a soil moisture sensor based on changes in capacitance. Compared to resistive sensors, capacitive sensors do not require direct exposure of metal electrodes, which can significantly reduce electrode erosion.

This is a small Force Sensitive Resistor . It has an Active Detection Area of 0.16 "(4mm) in Diameter. This FSR from Interlink Electronics varies its Resistance depending on how much Pressure is being applied to the Detection Area. The stronger the Force, the lower the Resistance. When there is no Pressure Applied to the FSR, its Resistance will be greater than 1MΩ, with the Total Pressure applied to the Resistance it will be 2.5kΩ Two Pins extend from the Bottom of the Sensor, making it friendly to the Breadboard. are simple to set up and great for detecting pressure.

The Reader of Capacitive Fingerprint is a Module of Fingerprint standard designed for Secondary Development, allows a Verification of Fingerprint Fast and Stable.

Based on a STM32F105R8 High Speed ​​Digital Processor, combined with high security commercial Fingerprint Algorithm and advanced semiconductor sensor, the capacitive fingerprint reader becomes a simple yet intelligent integration module, providing features such as registration digital printing, image processing, resource location, model generation and storage, fingerprint matching and research, etc.

Piezo Vibration Sensor - Large

GY-80 BMP085 Magnetic Field, Acceleration, Gyroscope

This sensor has a piezoelectric transducer that responds to voltage changes, generating a measurable change in output voltage that is proportional to the force of vibration . In this way, it is possible to know the vibration force , as opposed to the digital vibration sensor that only counts time.

Now, it's time to add a more sophisticated interactive way to your project. The DFRobot touch kit comes with three types of touch sensors . A ipod styple touch wheel, a touch touch screen that supports backlit and a grid touch pad that can recognize something unique.

This Load Sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales. This sensor can measure up to about 110 pounds.
