You are to design a circuit which monitors the temperature of an electric motor. It needs to update once every two seconds and report the current temperature. If the motor exceeds 70 degrees Celsius, an alarm must be sounded. Your job is to decide which MCU is most appropriate for this task. Your choices are ESP32, MSP432, and Seeeduino XIAO (SAMD21). Find reliable information to make a decision. You do not need to code the system but estimate its cost and performance using reliable information. You must provide references for all the the data that you compare. You should estimate speed, power, and cost. What is your alarm device
