GYMCU90640 is a low-cost non-contact infrared lattice temperature measurement module. Working voltage 3-5v, small volume. Its working principle is the law of blackbody radiation. The higher the temperature of the object, the stronger the infrared radiation ability emitted. The temperature data is obtained through chip processing. This module has two ways to read data, namely serial port (TTL level) or I2C (chip itself) communication mode. The product has a large number of temperature measuring lattice and high pixels. Can distinguish the size of a person in a general environment. The baud rates of serial ports are 9600bps, 115200bps and 460800bps, and there are two modes of continuous output and inquiry output, which can adapt to different working environments. Connect with all single-chip computers and computers. The module retains the I2C interface of the MLX90640 chip itself, and connects the module PS to GND or SET spot welding. The MCU of the module itself does not work and can be directly operated and MLX90640 through I2C.
