A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon.
In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are always used with other electronics.
Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into MARG sensors.
Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, robotics and many other aspects of our day-to-day life. There is a wide range of other sensors that measure chemical and physical properties of materials, including optical sensors for refractive index measurement, vibrational sensors for fluid viscosity measurement, and electro-chemical sensors for monitoring pH of fluids.
A sensor's sensitivity indicates how much its output changes when the input quantity it measures changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 °C, its sensitivity is 1 cm/°C (it is basically the slope dy/dx assuming a linear characteristic). Some sensors can also affect what they measure; for instance, a room temperature thermometer inserted into a hot cup of liquid cools the liquid while the liquid heats the thermometer. Sensors are usually designed to have a small effect on what is measured; making the sensor smaller often improves this and may introduce other advantages.Technological progress allows more and more sensors to be manufactured on a microscopic scale as microsensors using MEMS technology. In most cases, a microsensor reaches a significantly faster measurement time and higher sensitivity compared with macroscopic approaches. Due to the increasing demand for rapid, affordable and reliable information in today's world, disposable sensors—low-cost and easy‐to‐use devices for short‐term monitoring or single‐shot measurements—have recently gained growing importance. Using this class of sensors, critical analytical information can be obtained by anyone, anywhere and at any time, without the need for recalibration and worrying about contamination.
Yung proposed study ko po is Soil Sensor na may AI na makapag suggest ng pweding gawin sa current soil mo after niya ma scan, like Anong fertilizer or ilang percentage ng crop growth after niya ma scan. May prototyping na kami next month and I don't know what to buy, Anong klaseng sensor Yung...
Sa mga magaling dyan with coding, and IoT integration, pwede po bang mag ask if feasible yung project?
And can I ask nalang po suggestions in regards sa pagpili nung hardware, specifically choosing sa anong Arduino yung pipiliin, tas other sensors na lang po dun sa health monitoring na part.

I have a HWINFO64 sensor but walang option to become a widget. I played and watch on my laptop but due to high temp of our weather and my room is just a small room with a little to none airflow. I only have a dc fan 2pcs to cool my room and my laptop. I need a widget to continue monitor my temp...
mga boss, may nakasubok na ba sa inyo ng flow sensor YF-S401? inaccurate yung readings ng sensor eh. ginaya ko lang naman setup sa net same voltage din. pinalitan ko na rin yung component kasi akala ko defective. pero baka sa coding part na yung mali
Hello po. I'm new to Arduino. Kung pwede po sana makahingi ng help kasi di ko na po alam next na gagawin.
Eto po yung mechanics ng finals project ko.
Device that can play christmas songs. (1 song lang po samin na nakamedley)
Can be activated by sound and motion sensor.
No christmas lights...
