Analog Devices / Maxim Integrated MAX30205体温传感器
Maxim Integrated MAX30205体温传感器可准确测量体温并提供超温警报/中断/关断输出。MAX30205利用高分辨率Σ-Δ型模数转换器(ADC)将体温测量数据转换为数字形式。单次和关断模式有助于降低用电量。通过I2C兼容2线串行接口进行通信。
The I2C serial interface of the MAX30205 accepts standard write byte, read byte, send byte, and receive byte commands to read the temperature data and configure the behavior of the open-drain overtemperature shutdown output.
The MAX30205 features three select address lines with 32 available addresses. The sensor has a 2.7V to 3.3V supply voltage range, a low 600µA supply current, and a lockup-protected I2C-compatible interface that makes the device ideal for wearable fitness and medical applications.
The Analog Devices MAX30205 Human Body Temperature Sensor is available in an 8-pin TDFN package and operates over the 0°C to +50°C temperature range.
