hi,friend!welcome to my store, if you have any need and question, you can contact me any time.
if you buy products in my store,I can provide the top product and service to you.
The module performance is stable, measure the distance accurately. Can and foreign SRF05, SRF02 ultrasonic ranging modules and other comparable. Module precision, blind (2cm) super close, stable ranging success of this product according to market effectively!
the main technical parameters
1, the working voltage: DC 5V
2, the quiescent current: 2mA
3, level output: 5V High Low 0V
4: sensor angle: less than 15 degrees
5: Detection distance: 2cm-450cm
6: High: up to 0.3cm
7:Connection mode: VCC, trig (control side), echo (receiving end), GND
The product use: a control population of more than send a 10US high, you can wait for high output at the receiving port. One has to open the timer output can be, when the port goes low, the timer can be read the value of the, at this time for this distance of time, before calculate distance so the cycle of constantly measuring, you can move up the value of the measured
