Freenove ESP32-S3 CAM
Start by confirming the basic periodic capture behavior with a camera-equipped ESP32-S3 board.
Beehive Monitoring Module
Beehive MonitoringModule
A monitoring module for periodically photographing a beehive area and reviewing bee visits or surrounding changes later. Development starts with a Freenove ESP32-S3 CAM saving photos to an SD card.
The goal is to check whether bees are visiting the hive and whether the surrounding environment has changed without needing to visit the site each time.In the first stage, reliable photo capture and SD card storage are more important than communication features.
Overview
Turn changes around the hive into a record that can be reviewed later.
The module periodically photographs the beehive entrance and surrounding area, then stores the images as a time-based observation log. The intent is to review not only whether the hive was occupied, but also the location, box shape, and installation conditions.
SD card storage
Prioritize saving captured images locally before adding communication features.
Outdoor operation later
After the basic behavior works, move on to solar power, battery operation, and a 3D printed enclosure.
System
Start with USB power, then expand toward outdoor power.
The first prototype runs from USB power and saves photos from the ESP32-S3 CAM to an SD card at set intervals. After that, sleep behavior and power consumption will be checked before moving to solar charging and battery-powered outdoor use.
Freenove ESP32-S3 CAM board
The camera-equipped ESP32-S3 board is the center of the first capture and SD storage program.
Onboard camera and SD card
Captured images are saved to an SD card so visits and surrounding changes can be reviewed later.
Solar panel and battery
Once the basic behavior is stable, charging, supply, and power budget will be balanced.
3D printed enclosure
After the power layout and part placement are fixed, an outdoor enclosure will be designed.
Operation
Begin with SD storage, then move step by step toward field use.
The first version does not try to include every feature at once. Capture, storage, power, and enclosure design are checked in order so the device can eventually work outdoors.
01
Take photos with the ESP32-S3 CAM
Run the board from USB power and capture photos at a fixed interval.
02
Save images to SD
Save captured images to the SD card as a record that can be reviewed later.
03
Check sleep behavior and power draw
Review capture interval and standby consumption for longer outdoor operation.
04
Move to solar power and enclosure design
Combine the solar panel, battery, and power control parts, then 3D print an enclosure around the final layout.
Observation
Use failed attempts as information for the next placement.
A failed hive placement is hard to interpret from the final result alone. Image records can show whether scout bees came at all, how often they visited, and what installation conditions should be reviewed.
No scout bees visited
This may point to the location or surrounding environment not being discovered.
Visited but not chosen
This suggests reviewing the box shape, entrance, scent, height, direction, or placement.
Time and weather patterns
Images can help reveal when visits happen and how they relate to conditions.
Installation comparison
Multiple locations or boxes can be compared for future placement decisions.
