Infrared IR LED Pulse Detect Sensor Module Heart Rate Detect Measuring Module Measure Finger TL Module KY-039

Original price was: ₨450.Current price is: ₨300.

Operating Voltage: 5V
Using ultra-bright infrared (IR) LED and a photosensitive transistor to detect the pulse of the finger, a red LED will flash with the pulse
Working principle: As LED and photosensitive transistor are located on two sides of the finger, the photosensitive transistor is used to obtain light flux. When blood pressure pulsation passes through the finger, the resistance of the photosensitive transistor will change slightly
Number of sensor pins: 3Pins; Color: Black
Package Contents: Finger Pulse Detect Sensor Module

Availability: In stock
