The BME280 Atmospheric Sensor from Whadda is the easiest way to measure barometric pressure, humidity and temperature.

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.

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.

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.

Life has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled).
