The
Animal Activity Monitor incorporates highly sensitive electronic capacitive
sensors to detect vibratory movements on the platform of the animal cage.
The animal is placed inside an acrylic transparent cage that rests on the
sensor platform. Testing can be conducted in complete darkness,or in bright
sunlight. Ambient illumination is not a limiting factor as in most photocell
activity monitors.It detects ambulatory movements as well as stereotypic
activity like grooming, scratching, digging, etc. Vibrations caused by
the animal activity produce proportional electrical signals. These are
electronically processed to generate trigger pulses and drive a Digital
Counter. Every count registered is accompanied by a flashing LED and beeper.
The sensitivity of the animal activity monitor is adjustable as per user’s
experimental requirements.
An optional Timer is used
to programme experiment times from 1 to 99 minutes. |
