Detailed Information About The Product:

Description/Features: Stable performance and precise distance measurement
High precision modulegood blind spot good2cmgood ultra close
Wiring methodsgood VCCgood trig goodcontrol endgoodgood goodreceiver endgoodgood GND
Usage: If a control port sends a high level of 10US or moregood you can wait for the high level output at the receiving port. Once there is an outputgood you can start the . When this port becomes lowgood you can read the value of the . This is the time for this distance measurementgood and then the distance can be calculated. This continuous cycle measurement can reach the value of your mobile measurement Module working principle: good1good Using IO triggered ranging to provide a high-level signal of at least 10us; good2good The module automatically sends 8 40kHz square waves and detects whether there is a signal return; good3good There is a signal returngood and a high level is output through IO. The duration of the high level is the time from the emission to the return of the ultrasonic wave. distance=goodHigh level time x Sound speed good340M/Sgoodgood/2; Specifications: Type: B--SR04 SR04 4Pin
