Product Description:
Keep it cool with a Peltier module Thermoelectric Cooler . These unique electronic components can generate a temperature differential when powered. That is to say, apply 12V to the red (positive) and black (negative) wires and one side will get cold while the other side gets hot. For best results, you'll need to wick away that heat (otherwise the cold side will slowly get warmer). A fan and/or heatsink is ideal. This module is a 12V module, and is rated for ~72W max (up to 14V/6A) but when used with a regulated 12V output they don't draw more than 5A so we suggest our 12V/5A power adapter for use. -

ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during run time. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

Description: This Ceramic Piezo Vibration Piece Sensor buffers a piezoelectric transducer that responds to strain changes by generating a measurable output voltage change which is propotional with the strength of vibration.So you can know the extent of vibration. Different from digital vibration sensor that only accounts times, this analog one can tell extent of vibration. When the piezoelectric ceramic shocking will generate an electrical signal, Arduino Controller analog port can be perceived slight vibration signals, Also can be realized with vibration interactions related works, such as electronic drums. Marking "A" represents the module is a Analog Sensor, the other side graph represents function of the sensor. Easy identification!

The KY017 is a mercury tilt switch that allows you to detect the tilt of your object so that you can take the appropriate action. It is a nice low cost alternative to a 6 axis accelerometer. When strategically adjusted or situated, it can be very sensitive. The key to using this switch successfully is in understanding the two operational states.
