Tilt Sensor Module Tilt Switch Module For Robot Smart Car

ONE MODULE DESCRIPTION:

• The angle sensor can sense the change object
• Operating Voltage3.3V-5V
• Output Type Digital switching output (0And1)
• With fixed bolt hole for easy installation
• Small platesPCBSize:3cm * 1.6cm

TWO MODULE INTERFACE SPECIFICATION (3Wire )

• VCC External3.3V-5VVoltage ( directly with5vSCM and3.3vMicrocontroller is connected )
• GND ExternalGND
• DO Small board digital output interface (0And1)

Note:AOIn the mouth this is invalid , do not do any processing.

THREE INSTRUCTIONS:

• Tilt sensorMECOriginal tilt switchSW-460DHigh sensitivity, generally used to detect the object angle changes .
• Module without inclination or tilt angle of less than the threshold value,DOPort output high, when the tilt angle sensor exceeds the threshold , the moduleD0Output low.
• Small board digital outputD0Can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting an object angle changes.
• Small board digital outputDOOur relay module can directly drive , which can be composed of a tilt switch.

FOUR MODULE APPLICATIONS:

• Tire pressure monitoring system(TPMS), Bicycle lights , digital photo frame rotation, screen rotate, flip video camera , anti-theft system
• Five test instructions
• Use shop51Boards and tilt sensor module test

ConnectedVCCAndGND, Module power indicator lights

The module level light up the desktop, the module slowly rotating in one direction , the switch indicator lights , and then rotate the module in the opposite direction , back to the original state , the switch lights off. This phenomenon is explained , changing the angle sensor can trigger module , so that the switch indicator lights.

Phenomenon: change the angle of the trigger module , serial constantly sending01While the switch indicator light ;

No angle change does not trigger module , serial data is not sent , lights out.
