The use of multimedia wireless sensor networks (MWSN) has spread for many sensing applications. An MWSN was deployed for animal monitoring in the Amazon rainforest of Peru. Tapirduino, the developed trap camera sensor node, is composed by an Arduino-like PCB, a CMOS camera, an IR flash, a PIR sensor, a SD card, and 900-MHz radio. The challenges tackled in this project were to overcome the high attenuation of radio frequency in the middle of the jungle and to reduce energy consumption until achieving a very low level.
