M5StickT2

SKU:K016-T2

Description

M5StickT2is an exquisite and compact infrared thermal imaging camera. It adopts the latest FLIR Lepton 3.0 long-wave infrared (LWIR) camera core with an effective resolution of 160 * 120 for a clear and stable image. As it is a large area non-contact infrared sensor, it is a good solution for temperature measurement. Its main control chip is Espressif’s ESP32, which has built-in support for Wi-Fi connections, and computing speeds of up to 240Mhz. This provides a favorable guarantee for image output with a FPS reaching 7 and above. The screen is 1.14 inches and has a resolution of 135 * 240. The device comes with a rich variety of hardware resources: An on-board 6-axis Inertial Measurement Unit, a digital microphone and a power management chip and a built-in 300mAh battery, all embedded into the device. In terms of interactive operation, two programmable buttons and a rotary encoder are provided. In order to facilitate users to connect more peripherals, a 4 Pin HY2.0 interface with I2C support is provided at the bottom. The body is 3D printed from high quality Black Nylon filament. In addition, an M3 screw hole and a 1/4" screw hole are provided underside for easy mounting.

Power switch operation:

  • Power on :Long press power button for 2 seconds

  • Power off :Short press power button for 6 seconds

Usage

Press the reset button to power on. The default display screen is RGB display mode. The left side is the temperature image, the upper right is the power display, and the lower right is the histogram and temperature range. The temperature range is automatically adjusted with the target temperature. The default bulls-eye automatically tracks the maximum temperature. Press the button on the right side of the fuselage (B button) to switch the tracking mode (minimum / center / maximum value), press the button A on the front of the fuselage to switch the image display mode (GRAY / GOLDEN / RAINBOW / IRONBLACK / RGB). Dial encoder controls the display sensitivity (adjust the display temperature and color gamut), and long press the reset button for 6 seconds to turn off.
