Brand DYP Model DYP-ME008 Quantity 1 Color Red + green Material RF4 Features EYP-ME008 ultrasonic display modules using STC single-chip controller with an external serial port download ends two adjustable loops of switch value output three key setting select; Specification Electrical parameters: Operating voltage: DC 7~12V; Operating current: less then 50mA measuring accuracy: 1cm; Output (optional) open drain NPN PNP Power supply voltage output; Testing ranges: 0~500cm; Max. measuring distance: 500cm;Electrical parameters: Operating voltage: DC 7~12V; Operating current: less then 50mA measuring accuracy: 1cm; Output (optional) open drain NPN PNP Power supply voltage output; Testing ranges: 0~500cm; Max. measuring distance: 500cm Application Digital output module can be defined by the user specific methods are as follows: 1. Long press the S1 button for seconds or so display appears LLL 2. When press the S1 button display a number appears (100 default) for the minimum measurement limit values when the distance is less than the value measurement OUT1 output a low level (usually high) and LED light; This minimum measurement limit value allows the increase by pressing the S2 S3 reduced to change 3 When set the minimum measured value press button again display appears HHH set for maximum measurement limits press S1 to display for data (200 by default) for maximum measurement limits. When the measuring distance is less than this value output or NPN PNP power supply voltage open drain output. This maximum measurement limits enable increased by pressing S2 S3 reduced to change. When once the maximum measured value is set press S1 button save the values that you set with power off the storage function.
