SW-420 NC Type Vibration Sensor Module Vibration Switch For Arduino. If the module does not vibrate, the vibration switch was closed on state, output of low output, the green indicator light. The product vibrates, vibration switch momentary disconnect, output is driven high, the green light does not shine. The output can be directly connected with the microcontroller, which to detect high and low level, so as to detect whether the environment exist vibration, play a role in the alarm. Feature: Using SW-420 normally closed type vibration sensor Comparator output, clean signal, good waveform, strong driving ability, >15mA Working voltage 3.3V ~ 5V Output format: digital switching output (0 and 1) Using a wide voltage LM393 comparator With bolt holes for easy installation Small PCB size: 3.2 x 1.4cm Note: Power direction cannot be reversed, otherwise it is possible to burn the chip Signal LED light is output Low, signal LED OFF output is High The output level close to the input voltage Application: Various vibrations trigger: Arduino, Smart car, Earthquake alarm, Motorcycle Alarm, Theft alarm Package included: 1 x Vibration sensor module

Pre-set value is 3.3V. Just push a key to change the voltage settings and the data will be saved. When the voltage is below the set value, it will buzzer with red LED light.
W1209 Digital Temperature Control Switch is a programmable themrostat. The same module can be used in both controlling / maintaining Cold and Hot temperatures. Parameter 0 can be set to either Hot or Cold Control setting. The relay module is based on a microcontroller (MCU) and has 7 user configurable parameters accessible using 3 push button
4.1V~5V (not more than 5.1V, when using charger power supply, car charging power supply or DC-DC power supply, pay attention to the power supply voltage and ripple voltage, can string a diode)
This module is sensitive to the flame and radiation. It also can detect ordinary light source in the range of of a wavelength 760nm-1100 nm. It can be used as a flame alarm or in fire fighting robots.
