Small size, non-contact, low cost
Features at a glance
The MLX90640-D55 Thermal Camera is a small size, non-contact, and low cost IR array thermal imaging camera, with 32×24 pixels. It will detect the IR distribution of objects in the field of view, turn the data into surface temperature of the objects by calculation, and then generate thermal images, for easy integration into miscellaneous industrial or intelligent control applications.
- Adopts MLX90640 far-infrared thermal sensor array, 32×24 pixels
- Communicating via I2C interface, configurable to fast mode (up to 1MHz data rate)
- Noise Equivalent Temperature Difference (NETD) 0.1K RMS@1Hz refresh rate
- Onboard voltage translator, compatible with 3.3V/5V operating voltage
- Programable frame rate 0.5～64Hz (0.25～32FPS)
- Comes with development resources and manual (examples for Raspberry Pi/Arduino(ESP32)/STM32)
Typical applications:
- High precision non-contact temperature measurements
- IR thermal imaging devices, IR thermometers
- Smart home, intelligent building, intelligent lighting
- Industrial temperature control, security & safety, intrude/movement detection
