Application 1: Smart Private Garage

Materials: XIAO ESP32C3 *2, Grove - Button *1, Grove - Relay*1

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 - Wio - 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 trackers. 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.

Probably you are worried about the wireless capability of the above application of XIAO ESP32C3, and We have a 2.4GHz Rod Antenna for XIAO ESP32C3 which increases the wireless capability of the XIAO ESP32C3, The antenna is certified TELEC and XIAO ESP32C3 is compatible with Antenna.
