OPEN-SMART Ultrasonic Sensor Module + 4-Digit Display for Arduino

About Ultrasonic Range Sensor module:- This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process.- Arduino library ready: HCSR04Ultrasonic- Model: HC-SR04P- Operating voltage: 3~5.5VDC                                   - Static current: Less than 2mA.- IO logic voltage: 5V.- Sensor angle: Not more than 15 degrees.- Detection distance: 3cm~400cm.- Accuracy: 3mm- Adopt IO trigger through supplying at least 10us sequence of high level signal- The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal- If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. About 4-Digit Display module- The module is based on a decimal point display module, it displays four digital tube (0.36 inches), only two signal lines can make MCU control four Digit 8-segment LED. Can be used to display decimal, letters and so on.- Can display the measuring distance by the ultrasonic range module.- 8 class adjustable brightness- Operating voltage: 3.3-5.25V- IO logic voltage: 3.3V or 5VGeneralBrandOPEN-SMARTModelN/AQuantity1 setForm ColorBlue + BlackMaterialPCB+Alloy+PlasticSpecificationApplicationDistance MeasuringWorking Voltage DC 3~5.5VEnglish Manual / SpecYesDownload Link https://drive.google.com/drive/folders/0B6uNNXJ2z4CxR3h5RTZsUGpiM2c?usp=sharingOther FeaturesOther FeaturesA product for Arduino that works with official Arduino boards.Packing List1 * Ultrasonic Range Sensor module1 * 4-Digit Display modulePackage Weight:0.026kg (0.057lb)Package Size:6.5cm x 6.8cm x 3.5cm (2.36in x 2.36in x 1.18in)
