"Did you unplug it and plug it back in?" - every IT Person, ever. Field visits for simple instrument resets are a costly drain on resources. While most dataloggers have control ports that can power cycle devices and instruments, these ports are often exhausted as sensor density increases. By integrating a microcontroller, we have expanded our control capacity via multi-channel relay boards. Logic within the main datalogger verifies data transmission, validity, and connectivity before communicating with an external microcontroller that manages the power supply to individual devices and instruments. More importantly, we've moved beyond simple "On/Off" control by monitoring individual instrument's current draw in real-time. These data are passed to the primary datalogger, enabling automated notifications if hardware is drawing outside of specifications. Because the entire system can be monitored and controlled remotely, it provides a comprehensive "health check". This reduces unnecessary field visits and equips staff with additional diagnostic information needed to troubleshoot before leaving the office.
