MAX30205 is a high-accuracy, digital temperature sensor specifically designed for measuring human body temperature in medical and wearable applications. It’s a contact sensor, meaning it must be in physical contact with the skin to take a measurement. The sensor’s key features are its precision and low power consumption. It communicates with a microcontroller using the I²C protocol, which simplifies wiring and integration.
Description
The MAX30205 converts temperature readings into a digital format using a high-resolution sigma-delta analog-to-digital converter (ADC). It’s engineered to meet the clinical thermometry specifications of the ASTM E1112 standard, making it a reliable choice for medical devices. The sensor includes an open-drain output (OS) that can function as an over-temperature alarm, interrupt, or comparator, providing an immediate notification if a temperature threshold is exceeded. Its small form factor and low power draw make it ideal for battery-powered wearable devices.
Specifications
* Chipset: Maxim Integrated MAX30205
* Operating Voltage: 2.7V to 3.3V
* Temperature Range: Optimized for the human body temperature range of 0°C to +50°C.
* Accuracy: ±0.1°C accuracy in the critical human body temperature range of 37°C to 39°C.
