Are you searching for a temperature sensor having high accuracy? Then, LM75A IIC I2C High Accuracy Digital Temperature Sensor is perfect for you. It uses a thermistor as a form of resistance value to alter the Vcc. The resistance of a thermistor will increase when the ambient temperature decreases. It’s this characteristic that we use to calculate the ambient temperature. Depending on the temperature measured, it supplies an analog signal from 0 to 5 Vcc. The detectable range of this sensor is -55 to 125ºC and the accuracy is ±1.5ºC.
Based on LM75A, this is digital temperature sensor module.
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.
