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

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.

Monkmakes SSR (Monkmakes SSR)
Description:

The MonkMakes SSR is a low voltage solid state relay (no moving parts). This makes it super-easy to control loads of up to 2A at 16V from an Arduino, Raspberry Pi or other 3 or 5V microcontroller or single board computer.

This modern take on the electro-mechanical relay can even be used for low frequency PWM to control the power to its load.


Specifications:

This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a string of 12V LED lighting. The voltage needs to be kept under 16V, but the relay will automatically protect itself against too much current.

• Solid-sate relay up to 2 Amp Peak 1A continuous AC/DC
• Active LED indicator
• Resettable ‘polyfuse’ to protect against over-current
• Great for Arduino and Raspberry Pi
• Suitable for low frequency PWM

3V-5.5V HC-SR04P Ultrasonic Ranging Module (sensor ultrasonic 3V)
Description:

Ultrasonic Range finder has been very useful in many electronic project. It is low cost and teaches us the propagation of sound wave, learning about science while completing your project:) While it is popular, HC-SR04 ultrasonic sensor is 5V operated, so it is difficult to be used with 3.3V system like NodeMCU, Wemos, Raspberry pi, micro:bit or 3.3V Arduino board. No more waiting, we bring you the 3.0V to 5.5V Ultrasonic Ranging Module.

Using your echo-location abilities to detect tasty fish treats. Until genetic modifications catches up with our desires, we'll just have to make do with these handy 3V Ultrasonic Sonar Distance Sensor and a pair of flippers. These ubiquitous sensors are really common in robotics projects, but they can also be used for automation, interactive art and motion sensing. They work at about 2cm to 450cm(5V) or 400cm(3V) away, but we think 10cm-250cm will get you the best results.



These sensors are fast, fairly easy to use, and low cost. Unlike the more common HC-SR04 series, this model can be powered by 3V or 5V and the logic level will be the same. This makes this model great for use with just about any microcontroller or microcomputer. And, its HC-SR04 software compatible so just plug it in and it works the same! (Note the size is different from the HC-SR04 so you may need to make mounting adjustments)

Of course you can also use with 5V system such as Arduino UNO, Arduino Mini and Maker UNO.

Features:

  • Voltage: 3V - 5.5VDC
  • Current: 2.2mA
  • Measuring Range: 2cm - 450cm
  • Working Temperature: 0ºC to 70ºC
  • Compatible with HC-SR04 Ultrasonic Sonar Distance Sensor
  • Properly labelled pin assignment
  • Arduino and Raspberry Pi compatible
