Jargon buster
Plain-language definitions for the technical terms used above.
- 12-bit resolution
- 12-bit resolution means a value is represented with 12 binary digits, giving 4096 possible levels. For a sensor, analogue-to-digital converter or similar device, higher resolution divides the measured range into finer steps so smaller changes can be distinguished, provided the device's range and noise allow it.
- DS18B20
- The DS18B20 is a common digital temperature sensor, often supplied in a waterproof stainless-steel probe, that sends its readings to a microcontroller over a 1-Wire connection. It is a typical choice for adding temperature data to environmental or water-monitoring projects.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
