Description

Heartbeat sensor module – keys black. Features – 16 x 116 x 3mm (l x w x h). Ky-039 keys module. Ir emitter and receiver. 3 – 5V dc input. M2 mounting holes (centres 10mm apart). Designed to be compatible with standard 2. 54Mm sockets. Description – this component is ideally suited to adding heartbeat sensing to your project. This detection module combines a phototransistor and ir led, which when a finger is placed between will provide a varying signal. Reading this analogue signal you can interpret a change in signal as a heartbeat. As a simple module it will suit use within a large range of projects based on microcontrollers such as Arduino boards and the raspberry pi. The module has a m2 mounting hole allowing for its easy attachment to a multitude of surfaces. Pin description – s analogue output. 3 To 5v dc input. Ground. Please note this is a sensitive module and will experience noise from household lights and other sources as such
