M5Stick T-Lite Thermal Camera Dev Kit MLX90640

The M5Stick T-Lite is a compact, fully integrated thermal camera kit with online detection functionality, consisting of the M5StickC-Plus and the HAT THERMAL. The Melexis MLX90640-BAA infrared sensor is used, with a resolution of 32 × 24 pixels, a measurement range of -40 to 300 °C, and an accuracy of ±1.5 °C. The 1.14-inch TFT display shows the thermal image and temperature data in real-time, while the integrated Wi-Fi enables streaming over LAN and cloud.

Features:

• MLX90640-BAA infrared sensor with 32 × 24 px resolution, 110° × 75° field of view, and a measurement range of -40 to 300 °C with ±1.5 °C accuracy
• ESP32-PICO-D4 dual-core 240 MHz with Wi-Fi enables real-time streaming of the thermal image over LAN and cloud, as well as API access via EZData
• 1.14-inch TFT color display (240 × 135 px) for direct visualization of the thermal image and temperature data without external display
• Configurable high-temperature warning function – alarmed via buzzer or network when exceeding a threshold
• Compact all-in-one design with 160 mAh battery, USB-C charging port, Grove I2C port, and programmable button
• Support for UIFlow (Blockly/Python), MicroPython, and Arduino IDE for flexible firmware development

Application Examples:

• Contactless temperature monitoring of electronic components, motors, or control cabinets for overheating
• Building thermography – making thermal bridges, insulation deficiencies, and heating patterns in walls visible
• Person and motion detection through thermal detection for simple presence sensors
• Industrial process monitoring with real-time streaming via Wi-Fi and cloud integration through EZData
• Educational projects and prototypes for infrared thermometry, edge-AI, and IoT sensor applications
