Close menu

With this component the device output voltage and the current intensity can be measured simultaneously at the USB port of the computer. In this way, it is possible to check how high the current strength is in a setup with Arduino microcontrollers, in order to protect the PC from too high a current strength if necessary. It can also be used to check whether a current is flowing when a terminal device is being charged via the USB port.

Specifications:

Two-line display

Working range: current 0 ~ 2.5 A
Working range: voltage = 3 ~ 7.5 V
Resolution: voltage 10mV current 1mA
Error: voltage <± 1% current <± 2%

The tester uses a new generation of four and a half power dual-loop integral converter ICs with accurate bandgap reference, high accuracy range, high precision, stable and reliable performance and noise suppression capability.

Perfekt für schnelle, unkomplizierte Messungen

Aus meiner Sicht ideal für den Einstieg in die Welt der Arduino-Basteleien. Ermöglicht dir, schnell und einfach ein Gefühl dafür zu bekommen, was deine Schaltungen an Strom ziehen.

Ich habe es viel in Kombination mit der 8x8-LED-Matrix und dem Arduino UNO verwendet. Wollte sicher gehen, dass ich den UNO (oder gar USB-Anschluss) nicht mit den vielen LEDs überlaste. Ich konnte Programme auch durch das Messgerät hindurch auf den Arduino uploaden, ergo konnte alles permanent eingesteckt bleiben. Ich hab bei jedem Codingversuch ein paar mehr LEDs eingeschaltet und den Stromverbrauch ablesen können. Simpel und schnell.

Über die Messgenauigkeit kann ich nichts sagen, da ich keine Vergleichswerte habe. Gefühlt würde ich die exakten Werte nicht auf die Goldwaage legen. Für eine grobe Abschätzung reicht es aber auf jeden Fall locker. Und mehr brauche ich persönlich nicht.

Zum Vorkommentar: Bei mir sieht das Gerät exakt aus wie auf den Bildern (schwarz, "USB Detector", weiße Schrift). Die Kratzer habe ich, bis ich diesen Kommentar las, gar nicht wahrgenommen ... ja, gegens Licht sehe ich viele kleine Kratzer. Aber stören mich bei der Nutzung null.

Funktioniert wie es soll

Es funktioniert, jedoch entspricht das Gerät das ich bekommen hab in der Farbe nicht dem abgebildeten. Außerdem kam es bei mir verkratzt an jedoch macht es seinen Job wie es soll somit stört es mich persönlich nicht
