A sensor is a device that senses and responds to input from the physical environment. It produces an output signal to detect a physical phenomenon. The input can be various environmental phenomena, such as light, heat, motion, moisture, and pressure.

The output is typically a signal that can be displayed in a way that humans can understand. These are always used with other electronic devices and can be found in everyday objects such as touch-sensitive elevator buttons and lamps that can be controlled by touching the base.

Beginner Project Ideas

Motion Detector Alarm

Use a motion sensor (PIR) or an IR/ultrasonic combo to detect movement.
When motion is detected, trigger a buzzer or light.
Wiring: Motion sensor → Arduino digital pin; modules to power & ground; buzzer/LED on another pin.
Code: Read sensor pin, if HIGH then trigger alarm, else standby.

Temperature Logger

Use a temperature sensor (e.g., analog or digital) to read ambient temperature.
Log the readings to Serial Monitor or an SD card, or send to an IoT dashboard.
Wiring: Temperature sensor VCC → 5 V (or 3.3 V), GND → ground, output → analog (or digital) pin.
Code: Read analog/digital value, convert to °C, print or transmit data.

1. Where can I get a sensor module?

Sensors online shopping is now easy at Robocraze with best sensor prices with special offers and free shipping above Rs.500. Buy sensors online in bulk or smaller quantities at the best price on our website.

2. What is a sensor module?

Sensor are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter (for example: temperature, blood pressure, humidity, speed, etc.) into a signal that can be measured electrically.

3. What is the difference between a sensor and a module?

Modules (having extra electronic circuitry along with sensor) are electronic devices that detect and respond to some type of input from the physical environment. The sensor modules often contain extra components to make the sensor easy to use. Like voltage regulator and level shifter to use a 3,3V sensor with 5V, decoupling caps, current limit or pull up resistors, connection headers, etc.

4.What are the three main parts of sensor module?

Sensors, in their most general form, are systems possessing a variable number of components. Three basic components have already been identified: a sensor element, sensor packaging and connections, and sensor signal processing hardware.

5. What are the Types of Sensors?

There are different types of sensors are currently available, each with distinct capabilities and applications. Some common examples of these include photoelectric, particle, motion, metal, level, leak, humidity, gas and chemical, force, temperature, IR, ultrasonic, pressure, proximity, and touch sensors. Every sensor type is specifically designed to detect and respond to a particular physical phenomenon, such as proximity, pressure, moisture, motion, heat, or light. The selection of a particular sensor type is dependent on the application and the specific physical phenomenon that needs to be measured or detected.

6. What types of sensors are available online?

You’ll find a wide variety of sensor modules including light sensors, infrared and ultrasonic proximity/motion sensors, gas sensors (for air quality), temperature & humidity sensors, current/voltage sensors, load/force sensors, biomedical sensors and more.

7. Are these sensors compatible with Arduino & Raspberry Pi?

Yes. Many sensor modules are made to integrate easily with microcontrollers like Arduino and single-board computers like Raspberry Pi. For example, the site mentions they offer solutions “for hobbyists, students and professionals” and readily integrate with electronics/IoT boards.

8. Can I use these sensors for robotics and IoT projects?

Absolutely. The collection emphasises use in IoT, automation and electronics learning — sensors for motion detection, environmental monitoring, embedded systems and robotics are featured. So you can use these sensors in robotics arms, IoT home-automation, data-logging systems, and more.

9. Do you provide datasheets or tutorials for sensors?

While each module’s listing includes some specifications and features (input/output type, voltage, sensing range), the site also says there’s “technical guidance from experienced professionals available round-the-clock”. That implies you will find some support and likely tutorials, though you may need to check each specific product for full datasheets.

10. Are bulk discounts available for schools & labs?

Yes — the site includes a bulk-buy category (“Buy Sensors in Bulk / College Kits”) listed under the Sensors collection filters. So educational institutions, labs or groups can buy multiple units for discounts.
