EMoRo Ultrasonic Distance Sensor with Transmitters, Receiver and Control Circuit
Ultrasonic distance sensor HC – SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit.
The basic principle of work:
1. Using IO trigger for at least 10us high level signal.
2. The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
3. 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.
Wire connecting direct as following:
• 5V Supply
• Trigger Pulse Input
• Echo Pulse Output
• 0V Ground
Connectors are included so soldering on EMoRo2560 board is not necessary.
UltraSonic distance sensor mounting kit contains:
1x Ultrasonic distance sensor HC – SR04
2x M3 screw
1x 25 cm wire with connectors

From our early beginning we design new electronic products. In very short period we found out that by accepting new technology and therefore shortening time to make something fully functional can make us significantly different from our competition. Usually our customers came to us with some ideas and asked us to manufacture some quantity of desired product. Of course, if we design a product, organize components and materials purchase and finally make production and testing, we also provide agreed warranty for manufactured products. According to demands of our customers we can also provide service for only a part of whole process.
