3.3-5V 3-Wire Vibration Sensor Module (3 wire vibration sensor)
This module has a component that is able to detect the vibrations. Depending on the strength of the vibrations, using the built-in comparator on its outputs gives either digital (HIGH / LOW) or analog (0V-5V) signal.
Features
When the VCC and GND are connected, the power indicator will light up.
Put the module on the desktop, adjust the blue potentiometer on the board until the on-board switch indicator lights up, and then slightly turn back the potentiometer untill the indicator light turns off. Hit the desktop with your hand so the vibration shocks the sensor, the indicator light will go on. Vibration stops, indicator light will turn off.
Features
- Comparative output, clean signal, good waveform, strong driving ability, more than 15mA.
- Working voltage: 3.3V to 5V
- Output form: digital switch output (0 and 1)
- Equipped with fixed screw hole, easy to install
- PCB board size: 32mm x 14mm
- Uses the LM393 wide voltage comparator
When the VCC and GND are connected, the power indicator will light up.
Put the module on the desktop, adjust the blue potentiometer on the board until the on-board switch indicator lights up, and then slightly turn back the potentiometer untill the indicator light turns off. Hit the desktop with your hand so the vibration shocks the sensor, the indicator light will go on. Vibration stops, indicator light will turn off.
Module connection details
1. VCC: connect power positive
2. GND: connect power negative
3. DO: digital signal output
Application
It is used for all kinds of vibration triggering, theft alarm, intelligent car, electronic building block.....

Depending on how hard your relay works, you might want to add a heat sink to it.
Q:During continuity testing with my multimeter why does my relay on the AC side not switch on?
A: The below info was found at http://www.crydom.com/en/tech/newsletters/solid statements - bench test an ssr.pdf
A multimeter determines impedance by injecting a small amount of voltage through it's probes into the circuit being tested. It then measures the current flowing through the probes and calculates resistance. Easy enough; Resistance = Voltage / Current! However, as we just discussed above, a solid state relay’s output turns on by “stealing” a bit of voltage from the AC mains in order to supply current to the gate of the SCRs. Simply put, if the AC mains is not connected to the relay then the output cannot turn on. Since the voltage and current produced by a multimeter is not sufficient enough to turn on the SCRs, the output of a solid state relay will remain in the off state; even with the input signal applied. As a result, SSRs will sometimes fail an incoming inspection because the engineer expects to see a significant change in the output impedance when they turn on the relay.The most effective way to bench test a solid state relay is to construct a simple test circuit consisting of a DC power supply or battery (a 9Vdc battery will work fine in most cases ) and a 60W or 100W light bulb.

Depending on how hard your relay works, you might want to add a heat sink to it.
Q:During continuity testing with my multimeter why does my relay on the AC side not switch on?
A: The below info was found at http://www.crydom.com/en/tech/newsletters/solid statements - bench test an ssr.pdf
A multimeter determines impedance by injecting a small amount of voltage through it's probes into the circuit being tested. It then measures the current flowing through the probes and calculates resistance. Easy enough; Resistance = Voltage / Current! However, as we just discussed above, a solid state relay’s output turns on by “stealing” a bit of voltage from the AC mains in order to supply current to the gate of the SCRs. Simply put, if the AC mains is not connected to the relay then the output cannot turn on. Since the voltage and current produced by a multimeter is not sufficient enough to turn on the SCRs, the output of a solid state relay will remain in the off state; even with the input signal applied. As a result, SSRs will sometimes fail an incoming inspection because the engineer expects to see a significant change in the output impedance when they turn on the relay.The most effective way to bench test a solid state relay is to construct a simple test circuit consisting of a DC power supply or battery (a 9Vdc battery will work fine in most cases ) and a 60W or 100W light bulb.
TCRT5000L Reflective Infrared Sensor Photoelectric Switches (infrared switch)
This Reflective IR Sensor is a simple plastic casing with two elements - an IR LED and an IR phototransistor. You can control the IR LED and turn it on to bounce IR off objects to determine their reflectivity. White & light colored stuff will bounce the light, so you can detect it.
