With an optical amplifier to detect changes in blood volume and get human body's real-time heart rate. Generally, it can be worn on a finger tip, earlobe or other capillary ends. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> ==Features==<br /> *Low power consumption <br /> *High flexibility<br /> *Small and easy to install. <br /> <br /> ==Specification==<br /> *Electrical specification <br /> **Operation voltage: 1.8V-5.5V<br /> **Input device <br /> *Tech parameters<br /> **Operation temperature: -40°C-85°C<br /> **Lead free packaging, complying with ROHS standard. <br /> **Supply current: IQ = 100µA (typical)<br /> **90°phase margin(typical)<br /> **Adopt MCP6001 1MHZ low-consumption amplifier<br /> **1MHz gain bandwidth product (typical) <br /> **Adopt APDS-9008 analog input environment brightness sensor <br /> *Size 尺寸<br /> **1.27mm-pitch 4Pin interface <br /> **Size of the Switch: 5mm*5mm，<br /> **Size of the Board: 20mm*20mm<br /> <br /> *Connection method <br /> **Pin description: GND, VCC, signal output and NC(Empty). <br /> Note: This output signal is analog signal, which needs analog interface to detect(A0~A7). You can connect it to the pins--1,2,10,11 and 12 of the Sensorhub with correpsoinding pins-- IIC（A4）, IIC（A5）, A6, A2 and A0<br /> [[File: Microduino-Plush Sensor_rule1.jpg|600px|thumb|center]]<br /> [[File: Microduino-Plush Sensor_rule2.jpg|600px|thumb|center]]<br /> <br /> [[file:mCookie-sensorhub_rule.JPG|thumb|800px|center]]<br /> <br /> ==Document==<br /> *Chip: '''[[File: APDS-9008.pdf]]''' '''[[File: MCP6001.pdf]]'''<br /> *Schematic: '''[[File: Microduino_Pulse.Zip]]'''<br /> <br /> <br /> ==Development==<br /> ===Preparation===<br /> *Make sure you build Microduino development environment. If not, please refer to: [[Microduino Getting started]]<br /> *Core module selection <br /> **1.Adopt [[Microduino-CoreUSB]] or [[mCookie-CoreUSB]]. <br /> **2.Adopt [[Microduino-Core]] or [[Microduino-Core+]] together with [[Microduino-USBTTL]] for program download. <br /> <br /> ===Program===<br /> <br /> *Test Program: <br /> [https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Advanced_Tutorial/Microduino_Pulse_measurement Microduino_Pulse_measurement]<br /> <br /> ===Hardware Buildup===<br /> *All hardware needed(Except core module): [[Microduino-Cube-S1]], [[Microduino-OLED]], [[Microduino-Sensorhub]] and a USB cable as well as some connectors. <br /> *Stack all modules together, insert the pulse sensor into the A0 slot of [[Microduino-Sensorhub]] with the connector and connect [[Microduino-OLED]] with [[Microduino-Cube-S1]] board's IIC interface via an OLED wire. <br /> *Open test program, choose the right board, compile and download. <br /> *After download, you can see OLED's interaction interface. The first line shows pulse rate and the second lines displays time and calculate the total heartbeats. <br /> **The pulse sensor starts counting when you press your finger tip onto it and it will calculate heartbeats after around 10 seconds. <br /> **Move your finger away and the system will clear automatically . <br /> <br /> ==Application==<br /> Microduino-Pulse sensor can be applied in smart hand belt, detecting heartbeats during physical exercise so that you can adjust yourself. <br /> <br /> <br /> ===Project===<br /> <br /> ==Purchase==<br /> <br /> ==History==<br /> <br /> ==Pictures==<br /> <br /> *Front<br /> [[file: Microduino-Plush Sensor-F.JPG|thumb|600px|center|Microduino-Cube-Station Front]]<br /> *Back <br /> [[file: Microduino-Plush Sensor -b.JPG|thumb|600px|center|Microduino-Cube-Station Back]]<br /> |}</div>
