The MAX30207 is a low-power, high-accuracy digital temperature sensor with ±0.1°C accuracy from +30°C to +50°C and ±0.3°C accuracy from 0°C to +70°C. It provides a 16-bit resolution (0.005°C).

The 2mm x 2mm x 0.75mm package design has extremely low thermal mass and can be mounted on a flex PCB with only two conducting traces, allowing for minimal thermal conduction to the system PCB and accurate temperature measurements.

Data is transferred serially through the 1-Wire® protocol, which requires only one data line and a ground reference for communication. Power to the device is also provided using the same data line used for communication using parasite power circuitry inside the device. Each MAX30207 has its own unique 64-bit registration number factory programmed into the chip. This unique 64-bit registration number acts as the node address in a multidrop 1-Wire® network. In multidrop networks, optional GPIO pins may be used as address bits to identify each device's physical location.

Applications

  • Internet of Things (IoT) Sensors
  • Medical Thermometers
  • Wearable Body Temperature Monitors

Product Detail

The MAX30207 evaluation (EV) system provides a single platform to evaluate the MAX30207, a +/-0.1°C accurate temperature sensor. The EV system consists of two boards connected through headers, a MAX32630FTHR microcontroller board, and the MAX30207_INTERFACE_ EVKIT board. The EV system also includes a MAX30207_ SENSOR_FLEX_EVKIT flex module that holds the MAX30207 IC. The MAX32630FTHR contains the firmware necessary to use the PC GUI program and provides power to the MAX30207 interface board. The MAX30207 interface board ships with jumpers preinstalled to allow quick evaluation of the MAX30207.

Applications

  • Internet of Things (IoT) Sensors
  • Medical Thermometers
  • Wearable Body Temperature Monitors
