MAX31825ANT+

MAX31825ANT+ is a 1-Wire® temperature sensor with ±1°C accuracy. The sensor communicates over a 1-Wire® bus that, by definition, requires only one data line (and ground) for communication with a microcontroller. This sensor has a unique 64-bit serial code, which allows multiple MAX31825 ICs to reside on the same 1-Wire bus. In addition, it includes two address input pins that, using an external resistor and pin-strapping, allow one of 64 different addresses to be selected to identify each sensor's physical location. Therefore, it is simple to use one microprocessor to control many devices distributed over a large area. It is used in applications such as industrial equipment, communications equipment, data centre equipment, consumer equipment.
