TOSR02-T - USB / Wireless 5V 2-channel Relay Module Support for temperature sensor

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

A Module with GPRS Antenna, operation Wireless and SIM Card.

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.

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.

Can be used to monitor the heart rate of the patient and athlete. The result can be displayed on a screen via the serial port and can be saved for analysis.

Carbon monoxide detector with alarm - orno

This relay shield is capable of controlling 4 relays . The maximum switching power can be 360VA / 90W . It can be controlled directly by the Arduino by means of digital IOs digital with external power of 9v . With integrated xbee socket and APC220 socket, it can be controlled wirelessly via Xbee / bluetooth / APC220 . Make it an ideal solution for home automation and robotics.

DFRobot Relay Shield  V2.1 is a completely new design which is capable of controlling 4 relays at a time.

SparkFun humidity sensor - HIH-4030

The Kit Set of Torix Connectors is widely used in building wiring. By selecting the best insulation material, it is durable, corrosion free, anti-aging, pressure 4kv and against electric shock. It breaks the disadvantage of the traditional wiring method which is problematic in wiring, easy to leak, and easy to corrode.
