Zilogs

Zilogs are a class of compact, modular data-logging devices commonly used in field research, environmental monitoring, and small-scale automation projects. They are designed to chronicle sensor measurements with accurate timestamps and to operate in environments where power and connectivity are limited. A typical Zilogs system combines a low-power microcontroller, expandable sensor interfaces, local storage, and a wireless or wired communication option for data offload. Many designs emphasize modularity, allowing users to attach different sensor cartridges, power sources, and radios without redesigning the core hardware.

Key features often include low-power operation, real-time clock timing, multi-sensor support (I2C, SPI), removable storage such as SD cards or flash memory, and straightforward firmware that can log data at chosen intervals. Software ecosystems around Zilogs commonly support scripting or config-based setups, export data in common formats (CSV, JSON), and provide simple tools for data retrieval and calibration.

Applications include environmental sensing (air and water quality, temperature and humidity, soil moisture), agricultural automation, wildlife monitoring, weather stations, and industrial process logging. In education and hobbyist contexts, Zilogs serve as accessible platforms for learning about data collection and embedded systems.

Development and availability: Zilogs originated in open-hardware and maker communities as affordable, customizable logging platforms. Numerous community designs and commercial variants exist, varying in processor family, storage capacity, and sensor options.
