Product descriptionThe max30100 is an integrated pulse oximetry and heartrate monitor sensor solution. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals. The max30100 operates from 1. 8v and 3. 3v power sup..
MQ131 gas ozone detection sensor module (with analog and TTL level output). When the ozone gas exists, the sensor’s conductivity gets lower along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through potentiomete..
