The resistance in 25 °C is 10K (+- 1%)
It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings
the resistance of LDR will become low according to the intensity of light
Memory Size: 32K
Package Type : DIP 14
MAX30100 Pulse Oximeter Heart Rate Sensor Module cd4011 The resistance in 25 °CIntroduction : Heart Rate click carries Maxims MAX30100 integrated pulse oximetry and heart rate sensor. It is an optical sensor that derives its readings from emitting two wavelengths of light from two LEDs a red and an infrared one then measuring the absorbance of pulsing blood through a photo detector. Features : Type: Biomedical Applications: Developing algorithms for pulse oximetry and heart rate readings through the tip of a finger On board
