Company DFRobot probably don't need to imagine because it is always present in the world of developers and designers. It is engaged in the production of high quality plates, modules and other equipment working with the Arduino. Gravity is a series of sensors on these compounds, which is compatible in particular with Gravity DFRobot IO Expansion Shield for Arduino. Want to know more? We invite you to familiarize yourself with a ready-made range or contact our specialists.
Module with 12-bit analog-to-digital MCP4725 converter with EEPROM memory. It can precisely convert the digital signal into corresponding analog voltage signal. The analog signal can be also generated using the PWM in modules such as Arduino or Raspberry Pi. Working voltage is from 3.3 V to 5 V.
Monochrome matrix 8 x 16 LED with RGB diodes, it can display 7 colors and 20 standard images, supports image identified by the user. It can display numbers, letters and symbols. It is controlled using the I2C interface.
Module from the Gravity series enables the processing of the current signal from 0 mA to 25 mA into a voltage signal from 0 V to 3V. The sensor may be connected to the Gravity expansion module of pins V7.1. It is supplied with the voltage from 3.3 V to 5 V.
It allows for turning on and off devices that require power from 5V to 15V with a digital signal. Switching frequency up to 5 MHz. It has two mounting holes, two ARK connectors and a standard Grove series connector. The kit also includes a Grove cable. It is compatible with Arduino and other minikomputerami.
Digital isolator of signal I2C ffrom series Gravity. It protects the sensors from electrical interferences causing a read error through the isolation of I2C signal and providing isolated power to the sensor.
Module with multiplexer that allows you to connect 8 different digital I2C buses to one interface, for each, there are separate pins SDA (bus of data line) and SCL (clock line of the bus). The device operates with a supply voltage from 3 V to 5 V.
Module EEPROM from series Gravity, allows for memory expansion on the data with 256 KB in Arduino. Communication via the I2S interface. It saves data during a power outage. The EEPROM is characterized by an almost infinite number of read cycles, and very low energy consumption.
Module digital sensor of humidity and temperature DHT22 DFrobot company, provides precision measurement and has a fast response time combined with high reliability and resistance to interference. The sensor is very small, and its introduction into the system easily and quickly, making it a very good choice for any project that uses the sensors of...
Sensor module that combines the function of gesture recognition and touch. Allows to detect gestures from a distance of 0 to 30 cm, this distance may be adjustable in the above-mentioned range. Device connected to minikomputera allows you to identify by touch with 5 points and diagnostics 7 types of gestures.
In this category are as basic (for example, temperature sensors or liquid level in the tank), as well as additional modules (e.g., modules for increasing memory, or magnetic field sensors based on Hall effect). Thanks to them, not only in connection with the preservation capabilities of its platform and raise the level of computing power, but with us you will create a stunning design characterized by pure and efficient work. You should use your skills and experience to deal with other problems, such as the development of designs based on the heart rate sensors of the human heart.
Sensors gravity Arduino is just a tool that provides You with wonderful opportunities. However, it all depends on Your creativity, imagination and goals. If you need assistance in the selection order, we will gladly help you in the Assembly kit.
Automation of simple actions and system wyręczające us in duties is almost standard, which uses the sensors of Gravity. Although it may seem that the humidity sensors, temperature or even the pH of the soil suitable for use in home gardens and stations of weather conditions, often they can improve their work large farms. Manufacturers can continuously monitor the parameters of the earth, the weather or the situation, intervening when necessary.
Gravity Arduino is also suitable for private, office buildings, industrial buildings and warehouses. The gas sensors or temperature can indicate a failure or problem, informing the people in the room or in the immediate vicinity that there was anomaly that may pose a threat.
The more elements and sensors, the components of the protective system, including Your property or business safer.
