Yes! There are several sensors and automated systems that can detect changes in plants (e.g., growth, moisture, light, movement) and trigger a camera to capture images automatically. These are commonly used in plant research, smart farming, and time-lapse photography.
1. Sensors That Detect Plant Changes
(A) Growth & Movement Sensors
-
Time-lapse cameras (e.g., Brinno, Raspberry Pi + camera module)
-
Automatically take photos at intervals to track growth.
-
-
Laser displacement sensors
-
Measure tiny changes in plant height/stem movement.
-
-
Infrared/3D imaging (e.g., PlantEye, Phenospex)
-
Captures 3D models of plant structure over time.
-
(B) Environmental Sensors (Indirect Changes)
-
Soil moisture sensors (e.g., capacitive or resistive sensors)
-
Trigger photos when water levels change.
-
-
Light sensors (PAR sensors)
-
Detect photosynthetic activity changes.
-
-
Temperature/humidity sensors
-
Useful for tracking stress responses.
-
(C) Bioelectrical & Physiological Sensors
-
Plant electrophysiology sensors
-
Measure electrical signals in plants (e.g., responses to touch, drought).
-
-
Chlorophyll fluorescence sensors
-
Detect photosynthetic efficiency changes.
-
2. How to Automate Plant Photography?
Option 1: DIY (Raspberry Pi/Arduino)
-
Hardware:
-
RPi/Arduino + camera module (e.g., Pi Camera)
-
Sensors (moisture, light, growth)
-
-
Software:
-
Python/Node-RED to trigger photos when sensors detect changes.
-
Example: Take a photo when soil moisture drops below 30%.
-
Option 2: Commercial Smart Plant Monitors
-
PlantCam (by Brinno)
-
Time-lapse camera for plant growth tracking.
-
-
Edyn Garden Sensor
-
Monitors soil/light and can integrate with cameras.
-
-
FloraPulse
-
Measures plant water stress, can link to imaging systems.
-
Option 3: Advanced Research Systems
-
Phenotyping stations (e.g., LemnaTec, WIWAM)
-
Robotic imaging systems for high-throughput plant monitoring.
-
3. Applications
Precision agriculture – Detect disease/stress early.
Scientific research – Study plant responses to stimuli.
Indoor gardening – Automate care with smart systems.
Art/education – Create time-lapse videos of plant growth.
