Time-lapse photography is widely used to observe slow-changing processes such as construction progress, plant growth, environmental changes, and laboratory experiments. However, most available time-lapse solutions are either bulky, power-hungry, or dependent on continuous connectivity, making them unsuitable for long-term deployment in compact, remote, or hard-to-reach locations. There is a growing need for a small, low-power, and flexible time-lapse camera system that can operate both with and without network access.
This project presents a compact time-lapse camera system built using IndusBoard Coin, designed to operate in two modes to suit different deployment scenarios.
- Wi-Fi Mode allows the device to create its own access point, enabling users to configure capture intervals and stream live images through a web interface.
- SD Card Mode enables fully standalone operation, capturing images at predefined intervals and storing them locally on a microSD card for later retrieval.
The small 3cm form factor, built-in Wi-Fi, and ample GPIO availability of IndusBoard Coin make it suitable for portable and autonomous time-lapse deployments.
Key Features
- Dual operation modes: Wi-Fi (AP-based) and SD card standalone mode
- Compact design using IndusBoard Coin with built-in Wi-Fi
- OV2640 camera module support
- Configurable capture intervals (from seconds to hours)
- Web-based interface for live streaming and interval control (Wi-Fi mode)
- Local image storage on microSD card (SD mode)
- Low-power operation suitable for long-duration monitoring
- Flexible GPIO mapping configurable through software
Applications
- Construction and infrastructure progress monitoring
- Agricultural growth and seasonal change observation
- Environmental research near rivers, forests, and coastal areas
- Laboratory experiments involving slow physical or biological changes
- Manufacturing process observation and workflow analysis
- Remote monitoring where continuous human supervision is not feasible
This time-lapse camera design demonstrates how a compact, wireless development board like IndusBoard Coin can be used to build a versatile and deployable monitoring system. By supporting both connected and standalone operation, the solution adapts to a wide range of real-world conditions, making it suitable for industrial, research, and field applications where size, reliability, and autonomy are critical.
