Serial Ultrasonic Module: JSME007TX

We have a very cost-effective Ultrasonic Ranging Module :HC-SR04, but it need you to trigger the ranging and calculated the distance yourself. 

Here is a more easy use serial ultrasonic module JSME007TX. It will auto output the distance information via serial port after power on, you don't need to do any trigger and calculated, just need to read the serial pin and get the distance information. 

Specifications:

• power supply :5V DC
  
• quiescent current : <15mA
  
• effectual angle: <15°
  
• ranging distance : 2cm – 350 cm
  
• resolution : 0.3 cm
• Output cycle : 50ms
• Baud Rate : 9600

Output frame format （4Bytes）

• 1st Byte : 0xFF (Start bit, Fixed value)
• 2ed Byte: H_Data (High 8 bit of the distance)
• 3rd Byte: L_Date (Low 8 bit of the distance)
• 4th Byte: Check Sum (0XFF+H_DATA+L_DATA=SUM, Check SUM is the low 8 bit of the SUM)
