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

asked What kind of microcontroller would i need for a door lock with a keypad input?

I am creating a door lock that will use a keypad of 1-9 and i need to know where i can get a good microcontroller with a usb.

And got the following answer:

A microcontroller by itself will not accomplish what you are needing. You will need to get a microcontroller that you can program via a USB or RS232 interface. The microcontroller will need to exist on a PC circuit card with an I/O BUSS and Opto Relay. The microcontroller should have a SDK with it that you can use to connect to the microcontroller. An easier solution would be to buy a PLC. MicroLogix builds some nice PLCs and they already have optos and relays built in that you can control external items.

The usb relay interface perform very well with distinct applications which can be precise to energy distribution and protection. The relays include wide adjustment ranges having a scale that is definitely simple to read either in 3 or 4 digits according to the model. These usb relay interface assist in rising the flexibility from the applications, minimize the overall power and upkeep expenses. You will find relays which are utilized for common purposes which come in reputable designs with rapid replacement alternatives. And you will find models which might be utilised for industrial applications and heavier duty applications that work on substantial loads. These goods are made to meet the lifetime industrial handle wants with the applications.
Their latest items will be the Time counter, Timer Delay, usb relay interface, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and numerous others. The web site provides a detailed description of each and every model in numerous categories of usb relay interface couplings and sensors. These products are incredibly helpful for high-risk applications. The usb relay interface are also out there with options like many timing ranges and functions. The company is at present on the lookout for agents and dealers who can market and sell their factory created products. They are always on a lookout for building new and much more dependable solutions depending on the demands and requirements with the industry.
