Central module (commanding unit):

220x150x56 mm durable plastic box, with IP67 rating (water and dustrproof)
Micro-controller (CM2 unit) with a real-time clock (RTC) module
Sufficient memory, starting from 1 Gb
5.34 Ah Li-ion battery with the nominal voltage of 14.6 V, providing at least 30 d of working time with a single THM and a single RFID module, with the frequency of 1 Hz
Variable, module-dependent logging frequency
Optional GSM modem for the data transfer
Up to five water and dustproof (IP67) connectors (15 mm, 4 pins), compatible with all types of modules
Optional Ethernet,Usb and Serial (RS232) communication ports
Water and dustproof power connector with different number of pins (3) to prevent incorrect assembly
Water and dustproof power button, featuring two-coloured indicator LED, which, after pressing, can be used for checking status of the logger

THM module:

Two probes on each module, each containing humidity and temperature sensor
Probes have are mounted on a 5 - 10 cm long poles for a better fixation to the variety of substrates
Probes are connected to the module using inconspicuous, brown cable (2 mm wide) and the module itself connects to the central module using a grey cable (4 mm wide) with a variable lenght to suite the needs of each user
Probes and module are waterproof and dustproof (IP67), with the PTFE filter on the sensors and epoxy on electronic components.
The frequency of measurement is adjustable from 2 to 60 measurements per minute

RFID module:

Strong and flexible sensor coil in a glass-fiber casing with a variable length (10 - 20 cm), that can be placed around the nes
Inconspicuous brown coloring for better camouflage
Compatible with RFID chips of a small size (1.4 x 8 mm, ISO 11784/11785), that are embodied in the special flags on bird legs
Variable logging setting – constant or smart (just changes, saves memory and power)
Can save even incomplete readings (as “Unknown chip”)
The coil and module are waterproof and dustproof (IP67), with epoxy on electronic components.
The frequency of measurement is adjustable from 2 to 60 measurements per minute

Camera module:

Camera, able to save both photos and video footage with a variety of attachment options
HD resolution, wide 100° view angle
IR lighting for added visibility (at least 30 m) during poor light conditions
