A temperature sensor, as you can probably guess, detects changes in ambient temperature. They’re a key component in any device that relies on this information, like an automated gardening system which opens or closes a window in a greenhouse depending on the temperature inside. You'll often find temperature and humidity sensors bundled within the s...
As with temperature, there are several electronic means of measuring distance. For the most part, they work in a similar way: by putting out an impulse and examining the return signal for changes, much like echolocation. These sensors use the Time of Flight (ToF) principle, and calculate distance using the following equation:
Okay, so temperature and distance are more or less self-explanatory. But what exactly is MEMS? Well, it’s an acronym that stands for Micro-ElectroMechanical System. It covers tiny, fabricated machines, some of which are smaller than a micron wide. These machines form the basis of the accelerometers, gyroscopes and magnetometers which allow your pho...
The spectrum of light is far broader than the visible portion. We measure light in frequency or wavelengths: we perceive different frequencies as different colours: We can calculate the frequency of a given beam of light using the equation below. Frequencies higher or lower than the visible spectrum are known as infra-red or ultra-violet. As such, ...
Force and touch sensors convert physical force into electrical signals. Like the other sensors we’ve mentioned, these come in several different varieties, each suited to a slightly different application. Force-sensitive sensors are found in a many devices such as mobile phones, digital scales and also in your car, as part of the airbag triggering s...
Hopefully by now you've got an idea of the sorts of Arduino sensors available and what each of them do. There's plenty more detail to get into, and there's plenty of information out there on each of the sensors we've mentioned. If you want to try to get to grips with any of them, then why not start by putting together some of the sample projects we...
Simple sensors, like the photo-resistor for measuring light, work by measuring the voltage they provide to one of the analog sockets in the Arduino. You can do this by using the analogRead function. Other sensors are a bit more involved, and they require special software libraries to work with the hardware. More often than not, however, these ...
- Soil Moisture. A soil moisture sensor is used to measure the moisture of soil around plants. The sensor has two probes which are inserted into the soil. Current is run through the probes to give the sensor a measurement of the resistance between the two probes: More resistance means dryer soil.
- Air Flow. Air flow sensors detect how fast air is flowing through the sensor, typically measured in liters per minute. These sensors typically work by measuring the change in temperature over a surface due to the flow of air over that surface.
- Color. Color sensors detect the visible color of an object, typically as a combination of red, green, and blue intensities. This matches the way a computer stores colour as a combination of red, green, and blue (RGB).
- Magnetic field (Hall Effect) Hall effect sensors detect magnetic fields using the hall effect. The Hall effect is where a voltage is realised across an electrical conductor in relation to current flowing through the conductor and a present magnetic field.
Oct 26, 2021 · Proximity Sensor. Most proximity sensors for Arduino are based on the classic infrared design. The sensor emits beams of infrared light aimed straight ahead, which are then reflected off any surfaces they hit. The sensor detects returning beams and measures the difference in time between emitting a beam and receiving it back.

Apr 30, 2019 · This list of Arduino sensors and modules are in “module” form-factor. This means they already include things like current-limiting resistors, terminal posts, and potentiometers on-board to help you save time. While this makes creating with your Arduino simple, its not entirely necessary. For example, in lieu of the two-color LED module, you ...
