Fever click features a specially designed sensor, which is capable of accurate measurement of human body temperature. This Click board™ uses the MAX30205 human body temperature sensor with the accuracy rating that complies with the clinical thermometry specifications of the ASTM E1112 standard. In addition, the sensor offers an open drain programmable interrupt output and uses the industry standard I2C interface, enforced with the additional timeout feature, that prevents lockdown of the I2C bus. It includes some other features as well, such as the programmable interrupt pin polarity, improved accuracy in the range between 37.5 ℃ and 40.0 ℃, low power consumption feature, and more.

Fever click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
