Monitor the consumption of any appliance, electrical circuit or office equipment (lighting, sockets, security systems, heaters, air conditioning, etc.) individually with this compact device that works via Wifi so you can monitor everything through your smartphone.

This Voice Recognition Module with Microphone for Arduino can recognize up to 15 voice instructions and be suitable for most cases involving voice control. With this module, we can control cars or other electrical devices by voice.

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

Finger is a fingerprint sensor that makes fingerprint verification super simple.

The Uart protocol, compact size and ultra low power consumption make the use of MSStack series products very attractive. It performs fast fingerprint matching with the highest level of security and the ideal convenience of the user. You can program to set the level of comparison of the fingerprint recognition and the different security level. If you've ever thought about protecting your project with biometrics, don't forget to include this MSunit Finger.

This unit communicates with the M5Core by UART protocol connected via PORTC.

The Atlas Scientific pH circuit designs currently available on the Internet are outdated and use a significant number of overly complex analog components. Atlas Scientific has reinvented and refined the pH circuit of the past to a more modern and simple to use model.

Do you make time to talk to your Arduino? Maybe you should! The EasyVR Shield 3.0 is a voice recognition shield for Arduino boards integrating an EasyVR module. It includes all of the features of the EasyVR module in a shield form factor that simplifies connection to the Arduino main board and PC.

O SM5100B é um módulo GSM miniatura, quad-band 850 / EGSM 900 / DCS 1800 / PCS 1900, que pode ser integrado num grande número de projetos sem fios. Você pode usar este módulo para realizar quase qualquer coisa que um telemóvel normal pode - mensagens de texto SMS, GSM / GPRS, o TCP / IP, e muito mais!

The W5500 Ethernet Shield v1.0 can be used to provide your projects with internet connectivity.W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC and PHY embedded. The shield also have two Grove connectors and a microSD card socket to support projects which require storing large amounts of data from Grove sensor. The RJ45 port (Where the Ethernet cable is connected to) is low enough to allow you to stack more shields on top of this one if needed.

This board based on the latest SIMCOM SIM808 GSM/GPS module, it offers cellular GSM and GPRS data along with GPS technology for satellite navigation.
