5V 1-Channel Low Level Trigger Relay Module - HW-307B TCA9548A Note that the default servo

Note that the default servo pulse widths (usually 1ms to 2ms) may not give you a full 180 degrees of motion

which can resolve altitude at 0

5V power and logic voltage range

you can also read the analog output with any ADC to get the vibration condition

Higher Current-Sense Capability with External Sense Resistor (MAX472)

5V 1-Channel Low Level Trigger Relay Module - HW-307B TCA9548A Note that the default servoDetails: Equipped with high current relay 7250VAC@10A 30VDC@10A It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc Trigger current: 5mA Working voltage: 5V Module size: 50 x 26 x 18. 5mm (L x W x H) Four mounting bolts holes, diameter 3. 1mm Screw terminals (Terminal Block) provided (C, NC , NO) for quick and easy connection Flyback diode to protect your microcontroller Input Signal Pin connected to Burg stick for
