Allsen Rx – Tx Kit consists of a RF Transmitter and a Receiver. This kit is specially designed for using it in making wireless robots where one can press buttons provided on transmitter and move the robot in desired direction with a help of motors driven by motor driver circuit in receiver. Features:
- Buttons are provided in Transmitter Board to control motor directions.
- In built motor driver circuit in Receiver Board.
- DIP switch for Address Selection.
- Power and Motor Enable switches.
- On board LED for power, motor and connection indication.
- Both Transmitter and Receiver have voltage regulators.

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.

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 module allows you to detect when sound has exceeded a set point you select. Sound is detected via a microphone and fed into an LM393 op amp. The sound level set point is adjusted via an on board potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low.
