Description M5Stick T-Lite is an integrated thermal imaging temperature measurement device with online detection capabilities. It is mainly composed of M5StickC-Plus and HAT THERMAL, and uses the MLX90640-BAA infrared imaging sensor. The main controller is powered by the ESP32-PICO-D4 chip and supports WiFi. It features a 1.14-inch 135 x 240 TFT screen, built-in 160mAh battery, user button, power/reset button, microphone, and passive buzzer for compact thermal imaging applications. Users can set a high-temperature warning function and view temperature images and data in real time through cloud and local network access. M5 also provides an online data API interface, allowing remote image and data access through EZData for engineering project applications.
