Sensors What it is A sensor detects a physical quantity in the environment and converts that measurement into an electrical signal for monitoring and control. Different models measure different parameters such as temperature, pressure, light, proximity, motion, or other physical changes. Why you need it - Provides real time data to support automated decisions and safer operations - Improves visibility into processes and equipment status - Enables tighter control, energy efficiency, and predictive maintenance - Flexible integration with existing control systems and data loggers Key attributes Function Detects a physical parameter and outputs a signal suitable for monitoring and control. Output can be analog or digital depending on the model, allowing straightforward connection to controllers, PLCs, or data acquisition systems. Compatibility Designed to fit standard control architectures and common data interfaces. Supports typical electrical connections and can be selected to match your controller or data logger. Suitable for integration into automation, building management, or embedded systems. Size Compact form factors to fit into tight spaces. Various mounting options are available to suit different installation requirements. Material Housing options include plastic and metal constructions. Some models offer ruggedized builds and ingress protection for challenging environments. Performance High precision and stability over the operating range. Low drift and fast response suitable for real time monitoring. Calibrated to maintain accuracy across typical environmental conditions. Use scenarios Industrial automation Use sensors to monitor equipment temperature, vibration, or proximity in a production line. Data feeds into control systems to trigger maintenance alerts, optimize process flow, or prevent equipment faults. Smart building and energy management Deploy sensors to monitor ambient conditions, occupancy, light levels, or air quality. Use the data to adjust HVAC, lighting, and shading for comfort and energy efficiency without sacrificing performance. Consumer electronics and automotive applications Integrate sensors into devices to sense user presence, position, or environmental changes. Use signals to adapt device behavior, improve safety features, or enhance user experience. How to evaluate and select - Identify the physical parameter to measure and the required measurement range and accuracy - Choose an appropriate output interface (analog vs digital; voltage, current; I2C, SPI, UART, etc.) - Consider the installation environment and any protection needs (IP rating, enclosure type) - Confirm compatibility with existing controllers or data logging systems - Assess size constraints, mounting options, and environmental durability - Verify calibration and reported accuracy under expected operating conditions Maintenance and care - Periodically verify calibration against known references - Inspect mounting and connections for signs of wear or corrosion - Replace or recalibrate if drift or response time degrade beyond specifications - Follow manufacturer guidance for storage and handling to preserve performance
