Frequently Asked Questions
Q: What types of sensors are available in the Sensors & Meters collection?
A: Our Sensors & Meters collection includes pressure sensors and gauges, NTC thermistors, magnetic contact sensors, ultrasonic thickness gauge probes, piezo ceramic sensors, reflective photoelectric sensors, water level sensor modules, and more — covering a broad range of electronic measurement and sensing needs.
Q: Are these sensors compatible with Arduino and other microcontroller platforms?
A: Yes! Many of our sensors, such as the Air Pressure Water Level Sensor Modules and the QRE1113 Reflective Photoelectric Sensor Switches, are designed for easy integration with Arduino, Raspberry Pi, and similar microcontroller platforms via standard ADC or digital I/O interfaces.
Q: What is a thermistor and what are its common uses?
A: A thermistor is a type of resistor whose resistance changes significantly with temperature. Our 10K B3950 Magnetic Thermistor Sensors are commonly used in 3D printers, HVAC systems, refrigeration monitoring, and any application requiring precise temperature measurement.
Q: How do I choose the right pressure gauge for my application?
A: Consider the pressure range, connection size, and media type (fuel, oil, water, air) your application requires. For example, our 0–15 PSI Stainless Fuel & Oil Pressure Gauge uses a standard 1/8" NPT fitting and is ideal for low-pressure fuel and oil line monitoring in automotive or small engine applications.
Q: Do these sensors and meters come with any accessories or mounting hardware?
A: Accessories vary by product. Many sensors include pre-attached wiring with standard connectors (such as XH2.54-2P), while tools like the multimeter probes are sold as ready-to-use replacement sets. Check individual product pages for full details on included accessories and compatibility.
