USB Detector Current Voltage 3V-9V Tester Dual USB Dual display (USB Docter Dual)

Use the USB Charger Doctor to measure the working voltage and current output for any USB port and project. This plastic dongle plugs between a USB device, and passes the data lines through. There's a 0.05 ohm resistor in line with the power pin that is used to measure current draw. The Doctor's digital display instantly reads the numbers out for testing devices such as chargers, cables, and cell phones.

You can use this device from 3.5-7VDC input voltage (although most USB devices tend to hover around 4.75 to 5.25) and up to 3A of current. It displays both voltage and current readouts. It's a very handy tool for testing USB devices, checking load levels and debugging battery chargers and boost converters.

DC 5V WCS1800 Hall Current Detection Sensor Module 35A Precise With Overcurrent Signal LED (WCS1800 Hall Current)
Description:

The WCS1800 Hall Current sensor has two functions

  • current detection
  • over current protection (can be preset from 0.5A to 35.0A)

Features:

Operating voltage: DC 5V
Current detection range: DC +-35A, AC 25A
Linearity: K=60mV/A
Limit current range: 0.5A to 35A(for on/off value output)
Over current signal indicator LED
Sampling current conversion analog voltage signal output and it can connect ADC; TTL level signal output and it can connect MCU IO port control
Board size 37mm x 31mm
Working temperature: 25 to 85C

Interface



VCC: power positive
DOUT: TLL high/low level signal output
GND: power negative
AOUT: sampling current signal conversion voltage output port

Analog voltage signal output (AOUT)

Relationship between detection current and analog signal output is shown below:

Analog signal output: V0=Vcc*0.5±la*K (la is actual current through current detection pin, and K is linearity)

Eg: Input current is 1A, Vcc=5V and WS1800 linearity is 60mV/A
  1. When the current flows in from positive direction: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V
  2. When the current flows in from negative direction: V0=Vcc*0.5-la*K, V0=(2.5-0.06)V=2.44V
  3. If it is an AC signal: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V

The above are ideal values. There might be some precision errors.

On/Off output(DOUT)

  1. Make sure the current flows in from the positive direction. Adjust to the desired current warning level.
  2. LED will be on when current is below the setting and DOUT will be low.
  3. When the detected current is higher than your setting, the LED will turn off and the DOUT pin will go high.

Package Includes:

1 x WCS1800 Hall current detection sensor
