StickT2

SKU: K016-T2

Description

StickT2 is a compact and exquisite infrared thermal imager. It adopts the latest FLIR Lepton 3.0 long-wave infrared (LWIR) camera core, with an effective resolution of 160 x 120, providing clear and stable imaging. It is an excellent solution for large-area non-contact infrared temperature measurement. The main control chip is the ESP32, which supports Wi-Fi connectivity and has a computing power of up to 240MHz, ensuring smooth image output with a frame rate (FPS) of 7+.

The screen is 1.14 inches with a resolution of 135 x 240. Additionally, it is equipped with rich internal hardware resources, including two programmable buttons and a rotary encoder for interactive operations. It also features an onboard 6-axis IMU (MPU6886), a microphone (SPM1423), a power management chip (AXP192), and a built-in 300mAh battery.

For easy connection to peripherals, a 4P HY2.0 interface is provided on the side. The body is made of black nylon material through 3D printing, and it includes an M3 screw hole and a 1/4 screw hole at the bottom for mounting.

In terms of firmware, it offers up to 5 color display modes, allowing users to specify the measurement of maximum, minimum, or center values, and the display temperature range is adjustable.

Power On/Off:

  • Power On: Press the reset button for at least 2 seconds
  • Power Off: Press the reset button for at least 6 seconds

Usage Introduction

Press the reset button to enter the startup screen. By default, it enters RGB display mode, with the temperature image on the left, battery level display on the top right, and a histogram and temperature range on the bottom right. The temperature range adjusts automatically based on the target temperature. The default target automatically tracks the maximum temperature. Press the button on the right side of the body (Button B) to switch tracking modes (minimum/center/maximum). Press the front button (Button A) to switch image display modes (GRAY/GOLDEN/RAINBOW/IRONBLACK/RGB). The rotary encoder controls the display sensitivity (adjusting the display temperature range). Long press the reset button for 6 seconds to power off.
