Application 1: Smart Private Garage

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

Description:

This
is a peer-to-peerWiFicommunicationapplication,since two XIAOs detect
each othervia Wifi, the garage door will open or keep opening, and vice
versa.

Improvement:

It is nice to add anultrasonic distance sensor to measure the car-to-door distance and an OLED screen
to check the status of the garage. If you want an onboardvoice sensor
to command the door to open with vocal instruction, try our XIAO BLE
Sense. 

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. Thiswearabledevice can be
used as a simple GPS-Tracker which willlock its
currentlocation andpublishother datavia 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,thechipESP32-C3 allowsthis tracker to communicate over
WiFi or BLE, and therefore,wecan upload the tracker’s data or realizethe
Long Range-to-MQTT bridge as well.
