Reflective high-precision 3cm qhov muag tsis pom thaj tsam ultrasonic ntau yam finder (DYP-A20)

Cov yam ntxwv ntawm A20 module suav nrog millimeter daws teeb meem, 3cm txog 300cm ntau yam, kev tsim kho thiab ntau hom kev tso tawm: PWM pulse dav tso zis, UART tswj cov zis, UART tsis siv neeg tso zis, hloov cov zis, RS485 tso zis.

Tsis tas li ntawd, Firmware filtering rau lub suab nrov zoo heev thiab tsis kam lees

mm qib daws teeb meem
On-board kub them nyiaj ua haujlwm, tsis siv neeg kho qhov sib txawv ntawm qhov kub thiab txias, ruaj khov ntawm -15 ° C txog + 60 ° C
40kHz ultrasonic sensor ntsuas qhov kev ncua deb ntawm cov khoom
Raws li RoHS
Ntau qhov tso zis interfaces xaiv tau: PWM mem tes dav, UART tswj, UART tsis siv neeg, Hloov, RS485
Tuag band 3 cm
Qhov siab tshaj plaws yog 300 cm
Ua haujlwm voltage yog 3.3-5.0V, 5.0-24.0V (RS485)
Ua haujlwm tam sim no ≤8mA, ≤15mA (RS485)
Kev siv hluav taws xob tsawg tsim, standby tam sim no ≤5uA
Kev ntsuas qhov tseeb ntawm cov khoom dav hlau: ± (1 + S * 0.3%)cm, S sawv cev rau qhov ntsuas qhov deb
Me me thiab lub teeb module
Tsim kom yooj yim kev koom ua ke rau hauv koj qhov project lossis cov khoom
Ua haujlwm kub -15 ° C rau + 60 ° C
Waterproof IP67
