Sensors
Sensors are essential components of electronic and automation systems that enable the measurement, detection, and conversion of physical signals into electrical data. They allow monitoring of temperature, humidity, pressure, motion, magnetic fields, proximity, and many other environmental parameters. With their help, process automation, device protection, environmental condition analysis, and real-time control become possible
How Do Sensors Work?
Sensors convert physical quantities into analog or digital signals, which can be processed by electronic circuits. With modern communication interfaces such as I²C, SPI, UART, PWM, or analog outputs, sensors can be easily integrated into embedded systems, microcontrollers (e.g., Arduino, Raspberry Pi, ESP32), and PLCs.
Key Sensor Parameters
✔ Measurement range – defines the minimum and maximum values the sensor can detect
✔ Accuracy – the higher the precision, the better the measurement quality
✔ Response time – crucial in real-time systems
✔ Communication interface – analog (voltage, current) or digital (I²C, SPI, UART)
✔ Power consumption – essential for IoT and battery-powered devices
✔ Environmental resistance – water resistance, temperature range, EMI immunity
