Piezo Transducer - Mini 5V Buzzer (4000Hz) (buzzer pcb 5V)

Description:

If you want to add beeps, tones or alerts to your Raspberry Pi project, you require a Piezo Buzzer! This mini transducer is small but loud, and can be driven with a 1-20V peak-to-peak square wave. To use, connect one pin to ground (either one) and the other pin to a square wave out from a timer or microcontroller. For the loudest tones, stay around 4 KHz. For extra loudness, you can connect both pins to a microcontroller and swap which pin is high or low ('differential drive') for double the volume.

This one plops perfectly into a breadboard and has short legs, so can also easily be mounted on a PCB!

Please Note. This item is externally driven, e.g. requires a microcontroller to produce a tone.

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.

Liquid Water level sensor Side Mounted Float Switch (liquid level side mounted)

The liquid level switch detects the rising level of liquid in a sump or tank. It can be connected to a micro controller. It can then be used to start/stop a pump which then pumps liquid in/out until the level of the liquid has been restored to the point where the pump is switched off again. The switch may be used in a pump station, a sensor, a tank alarm, or other devices.

TEC1-12715 12V Peltier Plate Module (Peltier 12V 40x40)

Description: Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity.

This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or other block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortably cold we could not hold our finger to it.

Note: It is imperative that a heat sink is used on the hot side of the module. Running the module without one can cause damage to this part. If it’s too hot to comfortably touch, you’re in the danger zone!
