  • 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.

  • Description: Description: Description: Description: RHT02 output calibrated digital signal. It apply exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability. Its sensing elements is connected with 8-bit single-chip computer. Every sensor of this model is temperature compensated and calibrated in accurate calibration chamber and the calibration-coefficient is saved in type of program in OTP memory, when the sensor is detecting, it will cite coefficient from memory. Small size & low consumption & long transmission distance(100m) enable RHT02 to be suited in all kinds of harsh application occasions.
  • The AM2302 is a wired version of the DHT22, in a large plastic body. It is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed).
  • This is a breakout board for Freescale’s MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs.

  • 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!  
  • This is an elegant and innovative protective case designed specifically for the Raspberry Pi 2 Model B. Based on the best-selling SB Components' Model B case this two-piece injection-molded ABS enclosure incorporates snap-fit mounting points that hold the Pi securely in place. It provides tough protection for the Raspberry Pi Model B along with access to all the PI consumer ports as well as DSI, camera and GPIO connectors.
