When you place your finger on the board and it's authenticated, the LED ring will turn green.This is an environment detect device to collect PM2.5, PM10, temperature, humidity, CO2 and dust particle via Grove - Laser PM2.5 Sensor, Grove - CO2 & Temperature & Humidity sensor and Grove - dust Sensor respectively.
Gas Data LoggingTaking photos with the cameraUnleash the Power of Tracking with XIAO
This project shows how to log data with timestamps to a TF card using the XIAO ESP32S3 Sense. As an example, we’ll log temperature readings from the Multichannel Gas Sensor every 10 minutes. The XIAO ESP32S3 will be in deep sleep mode between each reading, and it will request the date and time using Network Time Protocol (NTP).The first project we will use the microSD card, the main task of this program is to get the camera footage every minute and then save the footage to the microSD.XIAO's low-power microcontroller, wireless connectivity, and compact size make it an ideal choice for developing cost-efficient trackers.
