The SparkFun Current Sensor Breakout is a High Precision Card that uses the ACS723 for Moderate AC and DC Current Detection Applications. The ACS723 Sensor uses a Hall Effect Sensor to Emit a Voltage relative to the Current that flows through the IP + and IP- Pins on the Board. The advantage of using a Hall Effect Sensor, specifically, is that the Circuit Being Detected and the Sensor Reading Circuit are Electrically Isolated, which means that although your Arduino is Operating at 5V, the Detected Circuit may be Operating at Higher DC or AC voltages.

This Kit integrates 10 Grove Modules and a Grove connection Shield on a single PCB board. All of these Modules and the Base Shield are already connected through the Wires on the PCB. This means that you only need to connect the Arduino Sensor Kit to the Arduino UNO or a Compatible Board (For example, SeeeduinoV4,2) and connect directly to a computer, then you can start programming and programming the Arduino with all sensors, actuators and OLED screens in the Arduino Sensor Kit.

Designed to facilitate the creation of IOT projects, the Arduino Oplà is based on a Arduino MKR WiFi 1010 , on which the Arduino wrapped in a plastic box. The kit includes a round OLED Display, along with Five Touch Buttons and Multiple Sensors to Monitor Air Pressure, Humidity, Light Intensity and Temperature. However, Additional Sensors must be simple to connect, like a PIR Sensor, which the Arduino also groups.

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.
