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

ACE asked In which direction is the best direction in which to approach engineering electronics, if any at all?

Radio Shack? Circuit board types, is there only one kind? What Do I need to learn about Transitors Resistors, compasitors ect ect...? What I need to know if I want to be serious about engineering electronics, or simply to modify an electronic component? Thanks.

And got the following answer:

Amateur Radio - aka Ham Radio - requires knowledge of basic electronics (and is a lot of fun if you are a techie who likes to get his hands dirty so to speak) Take a look at the hobby and see if it's something you might want to get into. For many electronic and electrical engineers, Ham Radio was a stepping stone into their professional careers. Once licensed - one of the many things you can do within the hobby is to build your own radios - either from scratch, or by purchasing kits. Note, Ham Radio electronic kits don't really get into surface mount components - too complicated to deal with micro sized parts, but these kits do use regular old PC boards and all the usual component parts - capacitors, resistors, inductors, relays, transistors, Integrated circiuts, etc. Browse for starters: WWW.ARRL.ORG WWW.ELECRAFT.COM WWW.EHAM.Net
