Problem

Millipedes require precise environmental conditions to thrive, yet maintaining consistent humidity, temperature, and nutrition in a terrarium can be labor-intensive. For hobbyists like Simar, frequent manual checks are not only time-consuming but also prone to human error, risking dehydration or cold shock that can harm or kill the colony. The lack of real-time visibility and alerting creates gaps between observations and action, making proactive care difficult.

Our team faced the challenge of delivering a reliable, remote monitoring solution that would reduce manual intervention while ensuring the wellbeing of millipedes. We needed an integrated approach that could sense multiple parameters, alert caretakers, and provide easy access to the enclosure without compromising the animals. The project required coordinating sensors, actuators, and microcontrollers into a cohesive, user-friendly system, all while keeping power and data footprints manageable.

Solution

We assembled a multifunctional IoT device—the Millipede Omnifunctional Monitor (MOM)—that links DHT11, IR, and load-cell sensors to three ESP32 microcontrollers. This architecture enables separate sensing, actuation, and data visualization pathways, allowing us to monitor humidity, temperature, and food levels in real time. The load cell detects food depletion and uses a color LED to indicate status, while the IR sensor controls a motorized lid for caretaker access. This modular design reduces manual checks and provides continuous visibility into the terrarium’s conditions.

We also built automation for safety and ease of use: the lid opens via IR-triggered actuation, a buzzer alerts on improper temperatures, and a multi-graph display showcases live sensor outputs. The IoT integration aggregates data to provide actionable insights and alerts, ensuring timely responses to varying conditions. The device is designed for local control and remote monitoring, enabling caretakers to maintain a healthier microecosystem from anywhere.
