Jargon buster
Plain-language definitions for the technical terms used above.
- IP67
- An ingress protection rating meaning the enclosure is dust-tight and can survive temporary immersion in water under specified test conditions. This matters when choosing a sensor for outdoor, wet, or wash-down environments.
- Modbus
- Modbus is an industrial communication protocol used by many meters, sensors, PLCs, and automation devices. Modbus support matters because it can make the controller easier to integrate with existing industrial equipment.
- ModBus-RTU
- ModBus-RTU is a common industrial protocol for sending sensor readings and control commands over serial links such as RS485. Knowing the sensor uses ModBus-RTU helps you choose software libraries, data loggers, or controllers that can request and interpret its readings.
- RS485
- RS485 is a robust wired serial communication standard often used in factories, farms, and buildings where cables may be long or electrically noisy. It matters because it lets this controller connect to industrial sensors, meters, and control equipment over longer distances than typical hobby serial wiring.
- Transmittance
- Transmittance describes how much light passes through the display or touch panel layers. Higher transmittance can make the screen appear brighter or clearer for the same backlight power.
