Sensors
Sensors convert physical phenomena — temperature, pressure, acceleration, magnetic fields, light, humidity, and proximity — into electrical signals that embedded systems can measure, process, and act upon. Octatronics catalogs sensor components from Honeywell, TE Connectivity, Allegro, ams-OSRAM, TDK InvenSense, and STMicroelectronics, with parametric search by measurement type, range, accuracy, output interface, and operating temperature.

Sensors are the perception layer of every smart system — from ADAS lidar modules and industrial vibration monitors to wearable health trackers and HVAC environmental controllers. The global trend toward IoT, Industry 4.0, and autonomous vehicles is driving exponential growth in sensor content per system.
This category includes magnetic sensors (Hall-effect switches, magnetoresistive), pressure sensors (absolute, differential, gauge), temperature sensors (thermistors, RTDs, digital), motion sensors (accelerometers, gyroscopes, IMUs), optical sensors (ambient light, proximity, color, spectral), and environmental sensors (humidity, gas, air quality). Key selection parameters include measurement range, resolution, accuracy, output type (analog, I²C, SPI), supply voltage, power consumption, and AEC-Q100 qualification.
On Octatronics, search sensors by measurement parameter, manufacturer, package, and interface. Compare accuracy specifications, review datasheets, and submit RFQs for both evaluation and production quantities.
