This is the Mini Reed Magnetic Sensor Module for Arduino! Reed switches are driven by magnets and are used in Mechanical Systems as Proximity Sensors.

This is the FeatherWing Adalogger: it adds a real-time clock with battery and micro SD card storage to any Feather mainboard. Using the Headers, you can connect a FeatherWing to the top of your board and let the board fly!

The 8 Environment Sensors Kit, M5Stack Env Kit, includes the 8 Earth, Angle, Pir, Hub, Light, Rgb, Ir and Env Sensors.

Color is a Light to Digital Color Converter with IR Filter. The TCS3472 Device provides a digital red, green, blue (RGB) return and sharp light detection values. An infrared blocking filter, integrated in the chip and located in the color-sensing photodiodes, minimizes the infrared spectral component of the received light and allows color measurements to be made accurately.

This unit communicates with the M5Core through the Grove (I2C) port. The address is 0x29.

The Earth Unit is a Sensor for measuring Humidity in Soil or Similar Materials. The Soil Moisture Sensor is quite simple to use. The two large stake-type sensors act as probes for the sensor, acting together as a variable resistance. The higher the moisture in the soil, the better the conductivity between the two, so that the sensor results in less resistance and higher GIS output.

You can read the moisture in the soil through ADC. Within this unit, there is an extra potentiometer to change the measurement range.

The Arduino WTV020-SD MP3 Module is a voice recording module with 1GB SD Card storage capacity. You can upload WAV and AD4 format files that conform to FAT formatting. It supports 6KHz to 32KHz, being 36KHz for AD4 files and 6-16KHz for voice sampling rate (Audio Sampling).

When you assign a high level to the module pin, the electro magnet can suck magnetically conductive objects. Otherwise, it will release the object.

An electro magnet is a type of magnet in which the magnetic field is produced by electric current. An electric current flowing in a wire creates a magnetic field around the wire, due to the Ampere Law. To focus the magnetic field on an electro magnet, the wire is wound into a coil with many twists of wire side by side. The Magnetic Field of All Twists of the Wire passes through the Coil Center, creating a Strong Magnetic Field there.
