SainSmart HC-SR04 Ranging Detector Mod Distance Sensor (Blue)

  • Using IO trigger for at least 10us high level signal
  • The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back
  • IF the signal back, through high level ,time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level time velocity of sound (340M/S) /2
  • Power supply :5V DC, quiescent current : <2mA,effectualangle: <15 ranging distance : 2cm~500 cm resolution : 0.3 cm

There are 4 pins out of the module: VCC , Trig, Echo, GND . So it's a very easy interface for controller to use it ranging. The all process is : pull the Trig pin to high level for more than 10us impulse , the module start ranging ; finish ranging , If you find an object in front , Echo pin will be high level , and based on the different distance, it will take the different duration of high level. So we can calculated the distance easily :Distance = ((Duration of high level)*(Sonic :340m/s))/2

amadeus93lee asked I want to control electronics from my parallel port... How do I make a relay?

I have been interested in controlling my tv, lamps, stereo, and anything else i want to by my computers parallel port. I have no idea what it takes to build a relay though. I want to build it, not buy an assembled one, or a kit. Any ideas?

And got the following answer:

The parallel port can also be accessed with COM control in VB6 or VB.net, see link http://support.microsoft.com/kb/823179 A solid state relay is a good choice, you can also buy a mechanical relay and build a driver circuit which takes just a few components, an optoisolator, a 2n2222 transisor, a 1000 ohm resistor, and a relay.

The relays in electronics work very well with diverse applications which can be distinct to energy distribution and protection. The relays come with wide adjustment ranges using a scale that may be easy to study either in three or 4 digits based on the model. These relays in electronics support in escalating the flexibility on the applications, cut down the overall power and maintenance expenses. You can find relays which are made use of for basic purposes which are available in trustworthy designs with speedy replacement alternatives. And you will find models which are applied for industrial applications and heavier duty applications that operate on massive loads. These solutions are made to meet the lifetime industrial control requirements on the applications.
Their latest goods are the Time counter, Timer Delay, relays in electronics, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and numerous other people. The site provides a detailed description of each and every model in several categories of relays in electronics couplings and sensors. These products are particularly beneficial for high-risk applications. The relays in electronics are also accessible with capabilities like many timing ranges and functions. The enterprise is at present looking for agents and dealers who can promote and sell their factory made items. They are generally on a lookout for creating new and much more reliable solutions based on the desires and specifications of the market.
