Based on LM75A, this is digital temperature sensor module.
LM75A is a high-speed I2C interface temperature sensor and it can converted the temperature into a digital signal directly in the temperature range of -55 ℃ ~ + 125 ℃.
MCU can read data from its internal registers directly through the I2C bus, and operate the 4 data registers to set different operation modes.
In the bottom of the module, you can select the I2C address, so that the same bus can connect eight devices without address conflict.
The module can not only measure the temperature but you can set the over-temperature protection temperature.
