Seeed Studio XIAO ESP32C3 - Tiny MCU Board with Wi-Fi and BLE for IoT Controlling Scenarios. Microcontroller with Battery Charge, Power Efficient, and Rich Interface for Tiny Machine Learning.
Application 1: Smart Private Garage Materials: XIAO ESP32C3 2, Grove - Button 1, Grove - Relay1 Description: This is a peer-to- peer WiFi communication application, since two XIAOs detect each other via Wifi, the garage door will open or keep opening, and vice versa. Improvement: It is nice to add an ultrasonic distance sensor to measure the car-to-door distance and an OLED screen to check the status of the garage. If you want an onboard voice sensor to command the door to open with vocal instruction, try our XIAO BLE Sense. Application 2: Remote Forest Tracker Materials: XIAO ESP32C3 1, Grove - LoRa E5 1, Grove - GPS 1 Description: Thanks to the tiny size of the XIAO series, it is suitable to make the wearable devices, such as a small pet tracker. This wearable device can be used as a simple GPS-Tracker which will lock its current location and publish other data via LoRa. Improvement: A compass that shows direction and distance is a great added value to the tracker that you could consider. Meanwhile, publishing altitude, speed, or other parameters could bring more scenarios to this tracker. Besides, the chip ESP32-C3 allows this tracker to communicate over WiFi or BLE, and therefore, we can upload the tracker’s data or realize the Long Range-to-MQTT bridge as well.
