Sensor-PIR The product number of Sensor-PIR is: MSDI51 Sensor-PIR is a pyroelectric infrared sensor that can detect infrared rays sent from moving human body or animals. It can output switch signals and be used in various occasions that need to detect moving human body. Introduction of Pins Pins of the sensor: PIN1: GND PIN2: VCC General signal pins: PIN3(IO1): digital/analog signal PIN4(IO2): NC(null) Special signal pins: If it is IIC: IO1/IO2 are respectively SDA/SCL. If it is soft serial port: IO1/IO2 are respectively tx/rx. Special to Sensor-PIR sensor pins PIN1: GND PIN2: VCC PIN3(IO1): Digital read PIN4(IO2): NC Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub. Features Adopt digital integrated pyroelectric infrared probe AM412. With high precision and sensitivity. Low power consumption, long service life and good stability. Digital signals Small size and easy to install. Specification Voltage 3.3V~5V working voltage Electrical specification Working current: 15uA Working temperature: -20~85℃ Output voltage: high level 5V, low level 0V Size Size of the board: 23.5mm*13mm 1.27mm-spacing 4Pin itnerface connected to sensorhub The CAD drawing of the sensor: File:Sensor CAD.zip Technical parameters Output delay（high level）: about 2.3~3s Induction angle: 100° Induction distance: 7m Connection This sensor can be connected to the following interfaces of core: D2~D13,A0~A7 Document Schematic diagram: File:Sensor-PIR.Zip Main chip: File:HS612 datasheet.pdf Development Program Download Download and unzip the program File:Sensor-PIR Test.zip Programming Follow the Software Getting Started Guide. Select the Board, Processor and Port. Click [File]->[Open], browse to the project program address, and click "Sensor-PIR Test.ino" to open the program. After confirming all these items are correct, click "→" to download the program to the development board. Hardware Setup Referring to the following diagram, connect the Sensor-PIR to the digital pin D6 of Microduino-Sensorhub. Result After download, open the serial monitor. The static sensor signal is LOW. After detect the IR emitted by living things within measurement range, it changes into HIGH. Application Intrusion alarm Non-contact infrared automatic switch Project History Gallery File:Microduino-Passive Infrared-F1.JPG Sensor-PIR Front File:Microduino-Passive Infrared-b1.JPG Sensor-PIR Back
