ULTRASONIC SENSOR HC SR04
- Voltage : 5VDC, 15mA, 40Hz, 2cm to 255cm,
- Measuring Angle : 15degree, 45*20*15mm
- Send IO trigger pin with at least 10us active high signal.
- The module will send automatically eight 40kHz pulse from the transmitter(thats why it is called ultrasonic). Any object detected will reflect the transmitted pulse back to the receiver.
- The signal return in active high level can be detected at pin ECHO. The high level time, which is time of high output duration from sending ultrasonic and returning, resembles the distance.
- Test distance = (high level time×velocity of sound (340M/S) / 2,
- Avoid soft objects as it will absorb most of the transmitted waves

Techmakers introduces our next generation solderless connectors. Innovative, Rugged design and simple, you just need a scredriver and a fraction of time to terminate VGA connector, saving you both time and money. Optimized for use in any A/V application where VGA interface and controls are still normally used. The contacts and terminal blocks are based on the industry standard, striving to deliver reliable A/V application.
The following is the VESA standard for wire colors for a standard VGA cable:
- (V) Vertical: White (or sometimes yellow)
- (H) Horizontal: Black
- (B) Blue
- (G) Green
- (R) Red
- Remaining 5 connectors are GROUNDS for each of the above. (Please take note that some of the VGA cables do not use standard wiring coloring. So, we would suggest you to use multimeter to test the wire and the pin-outs before doing the termination.
