Reference Designs

Creating a low-power: connected: microcontroller (MCU) based smart thermostat that can securely link a variety of sensors to the cloud: which enables remote monitoring and control: is the goal of most smart thermostat designers. The TIDM-1020 reference design provides a software reference for the implementation of such a smart thermostat: using the CC3220 device as the primary MCU: with Wi-Fi® connectivity. This application note provides the details of adding Bluetooth Low Energy (BLE) connectivity for provisioning to TIDM-1020.This reference design is for thermostat end equipment developers: engineers: and system evaluators. The design provides reference code to demonstrate integration of the CC3220SF device into a variety of analog and digital sensors: cloud connectivity services: human machine interfaces (HMIs): passive infrared (PIR) sensors: and external relay controls. This reference design is also intended to showcase: low-power connection to the Internet and cloud: remote control and programming: remote monitoring of the data: and secure Over The Air (OTA) update of the device and application firmware. This design demonstrates this system using either IBM Watson or AWS Cloud Services: and provides details on how to configure Alexa Voice Services (AVS) cloud for voice control from the cloud.
