DeepCover Embedded Security in IoT Authenticated Sensing and Notification
MAXREFDES143#
The MAXREFDES143# is an Internet of Things (IoT) embedded security reference design, built to protect an industrial sensing node by means of authentication and notification to a web server. The hardware includes a peripheral module representing a protected sensor node monitoring operating temperature and remaining life of a filter (simulated through ambient light sensing) and an mbed shield representing a controller node responsible for monitoring one or more sensor nodes. The design is hierarchical with each controller node communicating data from connected sensor nodes to a web server that maintains a centralized log and dispatches notifications as necessary. The mbed shield contains a Wi-Fi module, a DS2465 coprocessor with 1-Wire® master function, an LCD, LEDs, and pushbuttons. The protected sensor node contains a DS28E15 authenticator, a DS7505 temperature sensor, and a MAX44009 light sensor. The mbed shield communicates to a web server by the onboard Wi-Fi module and to the protected sensor node with I2C and 1-Wire. The MAXREFDES143# is equipped with a standard shield connector for immediate testing using an mbed board such as the MAX32600MBED#. The simplicity of this design enables rapid integration into any star-topology IoT network requiring the heightened security with low overhead provided by the SHA-256 symmetric-key algorithm.

SparkFun Qwiic Thermocouple Amplifier
MCP9600 (Screw Terminals)
The MCP9600 Breakout is a high accuracy Thermocouple Amplifier equipped with an I2C interface, accessed over our Qwiic system. Inside the chip are two temperature sensors, one for the thermocouple itself (the hot junction) and one for the chip itself (the cold junction). As a result, the MCP9600 can read both the ambient temperature and the temperature of whatever you're trying to measure! The MCP9600 can do both with a resolution of 0.0625°C, and an accuracy of ±1.5°C (worst-case). The MCP9600 Thermocouple Amplifier is one of our many Qwiic compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!

TMD37003 cRGB Color and Proximity Sensor
SEN-36004
Fully integrated carrier board designed to get the most out of the TMD37003 cRGB (color with IR compensation) and Proximity Sensor from AMS. This means that the board includes a 1.8V-5V input range LDO and high-speed signal voltage translation on all IO pins. In addition, we've added a high output white LED that is tuned to the light temperature range of the TMD37003 IC. This makes sensing color of close-proximity objects possible, such as in robotic color sorting operations. As on many of our boards, we've included 4-40 sized mounting holes to make installation easy. The IC functions are interfaced via a 0.1" header, which includes power (Vdd and GND), I2C interface (again, fully translated) and a 3.3V input to power the proximity (IR) LED. The on-board LED is turned on with a logic 'HIGH' applied to the LED pin and is powered with Vdd.
