Thermal2 Unit

SKU:U149

Description

UNIT Thermal2 is a data processing MCU-equipped MLX90640 thermal imaging acquisition unit. It has 32x24 imaging pixels, a field of view of 110°x75°, and a temperature measurement range of -40°C to 300°C. The MCU uses ESP32, which is capable of high and low temperature alarms, average, maximum and minimum values reading, and data caching via data processing. The board integrates with a buzzer, RGB indicator, function and reset buttons, and communicates with the host computer through I2C. This product can be used together with the host computer or separately, and is applicable for temperature measurement and abnormal alarms.
