Temperature Sensor Breakout Board

This board uses the NCT75-D temperature sensor which has a temperature accuracy of up to 1°C and temperature resolution of 0.0625°C.

The device also features an over-temperature alert pin which is highly configurable. The temperature is read via an I2C bus. Since the device has 3 address pins it is possible to connect 8 devices on the same bus, a useful feature for comparing temperatures at several locations at once.

The device can operate on either a 3V or 5V supply.

Features

• Accurate digital sensing
• Configurable over temperature alarm
