Summary
AJ-SR04M-T-X ultrasonic ranging module is designed by using a waterproof stripline probe integrated with transceiver and receiver and noncontact ultrasonic detection technology. In the range of 20 cm to 800 cm, the product can accurately detect the distance between plane objects, and
in the range of 20 cm to 250 cm, it can accurately measure people.
Basic working principle
After connecting the ultrasonic ranging module with 3-5.5V power supply, the module has five working modes:
Mode 1: Common Pulse Width Square Wave
→(Minimum power consumption 2.5mA)
Mode 2: Low Power Pulse Width Square Wave
→(Minimum power consumption 40uA)
Mode 3: Automatic Serial Port
→(Minimum power consumption 2.5mA)
Mode 4: Serial port trigger
→(Minimum power consumption 20uA)
Mode 5: ASCII code output
→(Minimum power consumption 20uA)
