This is a reflective sensor that includes a photodiode and phototransistor. The photodiode emit IR light and reflect from objects in front of the sensor, the reflected signal trigger the...

The LM393 amplifier module can be used to compare an input voltage with a predetermined voltage level. The LM393 IC contains 2 op-amps that are completely independent. In LM393 comparator...

This Omnidirectional Microphone offers a 500 uA current rating, 4.5V operating supply voltage, and -42dB sensitivity. Omnidirectional microphones can receive sound coming at all angles.FeaturesType: Electret Condenser Output Type: Analog...

On the back, we include a small trimmer pot to adjust the gain. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp!...

Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled board comes with a electret microphone soldered on and an amplifier that amplifies sound really...

This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year's resolutions,...

This straight bar load cell (sometimes called a strain gauge) can translate up to 1kg, 5kg or 20kg of pressure (force) into an electrical signal. Each load cell is able...

PZEM-004T V3.0 is the best for the purpose of the DIY project, where we need to measure the voltage, current, and power using Arduino/ESP8266/Raspberry Pi like opensource platform. In many...

This is SCT 013 30A Non-Invasive AC Current Sensor Split Core Type Clamp Meter Sensor. SCT-013- is a Non-Invasive AC current sensor i.e. it is a current transformer which can...

This current sensor is based on a current transformer. A current transformer (CT) is used for measurement of alternating electric currents. When current in a circuit is too high to...

This is a breakout board for the fully integrated Hall Effect based linear ACS712ELCTR-20A current sensor. The sensor gives current measurement for both AC and DC signals. The ACS712 outputs...

Measuring stretch forces isn't easy - unless you have some conductive rubber cord! This cord is 2mm diameter, and 1 meter long, made of carbon-black impregnated rubber. Usually this material...

This conductive material (also known as "Velostat" or "Linqstat") is a nice addition for your wearable/sensor hacking toolkit. It's pressure-sensitive: squeezing it will reduce the resistance, so it's handy for...

These are nice little ribbon controllers (also known as 'soft potentiometers') with an adhesive backing. This shape is a circular soft potentiometer with a donut-shaped sensing region whose outer diameter...

These are nice little ribbon controllers (also known as 'soft potentiometers') with an adhesive backing. There is a nominal 10K resistance across the two outer leads. The middle pin resistance...
